Its county seat is Yreka and its highest point is Mount Shasta . It falls within the Cascadia bioregion . Siskiyou County is in the Shasta Cascade region along the Oregon border. Because of its outdoor recreation, Mt. Shasta, McCloud River, and Gold Rush-era history, it
360-473: A U.S. state or other territories of the United States which consists of a geographic area with specific boundaries and usually some level of governmental authority. The term " county " is used in 48 states, while Louisiana and Alaska have functionally equivalent subdivisions called parishes and boroughs , respectively. Counties and other local governments exist as a matter of U.S. state law , so
540-1054: A city , town , or village . A few counties directly provide public transportation themselves, usually in the form of a simple bus system. However, in most counties, public transportation is provided by one of the following: a special district that is coterminous with the county (but exists separately from the county government), a multi-county regional transit authority, or a state agency. In western and southern states, more populated counties provide many facilities, such as airports, convention centers , museums, recreation centers , beaches, harbors, zoos, clinics, law libraries , and public housing . They provide services such as child and family services, elder services, mental health services, welfare services, veterans assistance services, animal control , probation supervision, historic preservation, food safety regulation, and environmental health services. They have many additional officials like public defenders , arts commissioners, human rights commissioners, and planning commissioners. There may be
720-446: A consolidated city-county or independent city exists, a city council usually governs city/county or city affairs. In some counties, day-to-day operations are overseen by an elected county executive or by a chief administrative officer or county administrator who reports to the board, the mayor, or both. In many states, the board in charge of a county holds powers that transcend all three traditional branches of government. It has

Counties are most often named for people, often political figures or early settlers, with over 2,100 of the 3,144 total so named. The most common county name, with 31, is Washington County , for America's first president, George Washington . Up until 1871, there was a Washington County within the District of Columbia , but it
1440-658: A ford on the Umpqua River by Michel Laframboise and his Hudson's Bay Company trappers in 1832. Others claim the Six Cailloux name was appropriated by Stephen Meek , another Hudson's Bay Company trapper who discovered Scott Valley, for a crossing on the Klamath River near Hornbrook . The county is home to the Black Bear Ranch , a commune started in 1968 with the slogan "Free Land for free people." On September 4, 2013,

1980-453: A large number of counties, and many Western states were sparsely populated when counties were created by their respective state legislatures. The five counties of Rhode Island and eight of the 14 counties of Massachusetts no longer have functional county governments, but continue to exist as legal and census entities. Connecticut abolished county governments in 1960, leaving its eight counties as mere legal and census entities. In 2022,

Species that were once common but now are endangered or gone include the southwestern willow flycatcher , western yellow-billed cuckoo , least Bell's vireo , and warbling vireo . Another reason for dropping numbers are the introduction of non-native species, such as
2340-564: A large proportion of their population within a few decades of the arrival of Sutter and the following settlers, the start of the gold rush , not to mention the numerous battles fought between the settlers and native bands as well as the forced relocation of some of the tribes to Indian reservations in several places scattered around the Sacramento Valley, mainly in the Coast Ranges. In the early 1850s, several treaties were signed between
2520-571: A new state from several counties of northern California and the adjoining counties of southern Oregon. The movement has seen a revival in recent years. The origin of the word Siskiyou is not known. It may be a Chinook Jargon word for a "bob-tailed horse" (ultimately originating in Cree ), or as was argued before the State Senate in 1852, from the French Six Cailloux (six stones), a name given to
2700-637: A part in the formation of the 300-mile (480 km) Monterey Submarine Canyon when sea levels were lower during the Ice Ages. The Monterey Bay outlet of the Sacramento and San Joaquin rivers was blocked off by uplift about 2 million years ago, and runoff from the Sierra began to transform the Central Valley into a gigantic lake, called Lake Clyde . This lake stretched 500 miles (800 km) north to south and
2880-403: A plethora of massive changes to the environment beginning in the 20th century. An early project was undertaken to raise the entire city of Sacramento about 11 feet (3.4 m) above its original elevation. This was followed by much bigger engineering projects to control and store the floodwaters of the Sacramento River; the building of these public works would radically transform the river during

Beyond Red Bluff the river reaches the low floodplain of the Sacramento Valley, receiving Mill Creek from the east and Thomes Creek from the west near Los Molinos , then Deer Creek from the east near Vina . Southeast of Corning , the Sacramento forms the boundary of Tehama County to the west and Butte County to
3600-600: A total of over 3,000 cubic feet per second (85 m /s) of water to irrigate some 150,000 acres (610 km ). In 1960, construction began on the State Water Project, whose primary purpose was to deliver water to Los Angeles and the San Francisco Bay Area. Oroville Dam – the tallest dam in the U.S. – was built on the Sacramento's largest tributary, the Feather River. A series of channels were enlarged in
3780-475: A turning point in the history of the Sacramento Valley, and California as a whole. In 1841, Sutter and his men built a fortress at the confluence of the Sacramento and American Rivers and the Mexican government granted him almost 50,000 acres (200 km ) of land surrounding the two rivers. Naming it New Helvetia, he created an agricultural empire in the lower Sacramento Valley, attracting several hundred settlers to

The Sacramento is by far the largest contributor of fresh water to the Delta; in an average year, it accounts for more than 80 percent of the fresh water inflow. At Walnut Grove , the manmade Delta Cross Channel connects
4140-428: Is Lake . Words from Native American languages, as well as the names of Native American leaders and tribes, lend their names to many counties. Quite a few counties bear names of French or Spanish origin, such as Marquette County being named after French missionary Father Jacques Marquette .

The most extensive county or county equivalent is the Yukon–Koyukuk Census Area, Alaska , with a land area of 145,505 square miles (376,856 km ). All nine of the most extensive county equivalents are in Alaska. The most extensive county is San Bernardino County, California , with
4500-424: Is 43 miles (69 km) long and is maintained to a depth of 30 feet (9.1 m). The Sacramento River and its drainage basin once supported extensive riparian habitat and marshes , in both the Sacramento Valley and the Delta, home to a diverse array of flora and fauna. Due to the reclamation of land for agriculture and the regulation of seasonal flooding, the amount of water-based habitat declined greatly during
4680-635: Is an important tourist destination within the state. Siskiyou County was created on March 22, 1852, from parts of Shasta and Klamath Counties, and named after the Siskiyou mountain range . Parts of the county's territory were given to Modoc County in 1855. The county is the site of the central section of the Siskiyou Trail , which ran between California's Central Valley and the Pacific Northwest . The Siskiyou Trail followed indigenous footpaths, and

In Connecticut and parts of Massachusetts, regional councils have been established to partially fill the void left behind by the abolished county governments. The regional councils' authority is limited compared with a county government—they have authority only over infrastructure and land use planning, distribution of state and federal funds for infrastructure projects, emergency preparedness, and limited law enforcement duties.

In most Midwestern and Northeastern states, counties are further subdivided into townships or towns , which sometimes exercise local powers or administration. Throughout the United States, counties may contain other independent, self-governing municipalities . In New England, counties function at most as judicial court districts and sheriff's departments (presently, in Connecticut only as judicial court districts—and in Rhode Island , they have lost both those functions and most others but they are still used by

Furthermore, county-level trial court judges are officers of
5940-557: Is simultaneously a city, which is a municipality (municipal corporation), and a county, which is an administrative division of a state, having the powers and responsibilities of both types of entities. The city limit or jurisdiction is synonymous with the county line, as the two administrative entities become a non-dichotomous single entity. For this reason, a consolidated city-county is officially remarked as name of city – name of county (i.e., Augusta–Richmond County in Georgia). The same
6120-501: Is true of the boroughs of New York City , each of which is coextensive with a county of New York State. For those entities in which the city uses the same name as the county, city and county of name may be used (i.e., City and County of Denver in Colorado). Similarly, some of Alaska 's boroughs have merged with their principal cities, creating unified city-boroughs. Some such consolidations and mergers have created cities that rank among

A large Crystal Geyser plant is at the base of Mt. Shasta, near Weed. Substantial amounts of the county are forested within the Siskiyou and Cascade Ranges, including significant oak woodland and mixed conifer forests . Siskiyou County is the northern extent of
6480-634: The Alaska Constitutional Convention wanted to avoid the traditional county system and adopted their own unique model with different types of boroughs varying in powers and duties. In some states, these powers are partly or mostly devolved to the counties' smaller divisions usually called townships , though in New York, New England and Wisconsin they are called "towns". The county may or may not be able to override its townships on certain matters, depending on state law. The newest county in

The next visitors were Hudson's Bay Company (HBC) fur trappers exploring southwards from the disputed Oregon Country , starting in the 1820s. The first organized expedition, led by Peter Skene Ogden , arrived in the area of Mount Shasta in 1826. By this time, California

The Freeport gauge, which sits just downstream of Sacramento, provides a relatively good metric of the annual outflow from the Sacramento River Basin. The average flow between 1949 and 2013
13320-568: The Sacramento Valley is below 300 feet (91 m) in elevation; in its lower course, the Sacramento River drops only about 1 foot (0.30 m) per mile. Between the bajadas or alluvial slopes extending from the foothills of the Sierra Nevada and Coast Ranges, are the low floodplains of the Sacramento River. The river flows at an elevation somewhat higher than the surrounding terrain due to deposits of sediment over millennia that created raised banks (essentially natural levees ). The banks separate
13500-519: The Sacramento and Feather Rivers into the Yolo Bypass , which parallels the Sacramento River down the west side of the valley. Cache Creek and Putah Creek , two major tributaries which formerly joined the Sacramento River from the west, are now intercepted by the Yolo Bypass via man-made channels. The main channel of the Sacramento flows south, forming the Yolo– Sacramento County line. As
13680-658: The Sacramento are that of the Klamath in the north, the San Joaquin and Mokelumne to the south and the Eel River in the west. The Russian River also lies to the west and the endorheic (closed) Honey Lake and Eagle Lake basins to the north. On the east side are many endorheic watersheds of the Great Basin including the Truckee River and Carson River . Parts of the Sacramento watershed come very close to, but do not extend past,
13860-692: The Sacramento to the Mokelumne River channel, allowing a portion of the water to be pumped south toward Clifton Court Forebay , the receiving reservoir for the main CVP and State Water Project aqueducts which irrigate millions of acres and supply water to over 23 million people in the San Joaquin Valley , the San Francisco Bay Area and Greater Los Angeles . Although river levels are tidally influenced here and occasionally as far north as Verona,
14040-479: The Sacramento with a portion of its historic flood plain, which it would have naturally flooded had the levee system not been in place. During the Great Depression in the 1930s, the first concrete proposals for a statewide water engineering project emerged, but when the state government could not sell the necessary bonds to fund the project, the federal government took over. The Central Valley Project , one of
14220-466: The Sacramento's main tributaries, enabling the regulation of water for irrigation and hydroelectric power. Starting in the late 1950s, two major canals were extended to irrigate the western side of the Sacramento Valley – the Tehama-Colusa and Corning Canals . Starting at the Red Bluff Diversion Dam on the Sacramento, the canals are 111 and 21 mi (179 and 34 km) long respectively, and divert
14400-529: The Sierra Nevada. The watershed also has Lassen Volcanic National Park , which covers 106,000 acres (430 km ) centered on Lassen Peak, the southernmost Cascade volcano. Whiskeytown-Shasta-Trinity National Recreation Area , which is over 200,000 acres (810 km ) in size, straddles much of the upper Sacramento and Trinity Rivers, and is named for the three local reservoirs (Shasta Lake, Trinity Lake and Whiskeytown Lake ) which are popular tourist areas. Many other state parks and recreation areas lie within
14580-580: The Siskiyou County Board of Supervisors voted 4 to 1 to secede from the State of California. According to the U.S. Census Bureau , the county has a total area of 6,347 square miles (16,440 km), of which 6,278 square miles (16,260 km) is land and 69 square miles (180 km), or 1.1%, is water. It is the fifth-largest county by area in California. Siskiyou County is geographically diverse. From towering Mount Shasta (elev. 14,179 ft; 4,322 m) near
14760-644: The U.S. Census Bureau began to also count Connecticut's Councils of Governments , which took over some of the regional powers from the state's former county governments, as county equivalents. Territories of the United States do not have counties; instead, the United States Census Bureau also divides them into county equivalents. The U.S. Census Bureau counts American Samoa 's districts and atolls as county equivalents. American Samoa locally has places called "counties", but these entities are considered to be " minor civil divisions " (not true counties) by
14940-473: The U.S. Census Bureau recognized the state's nine Councils of Governments as replacement for the state's eight legacy counties for all statistical purposes; full implementation was completed in 2024. The average U.S. county population was 104,435 in 2019, while the median county, which is Nicholas County, West Virginia , had a population of 25,965 in 2019. The most populous county is Los Angeles County, California , with 10,014,009 residents in 2020. This number
15120-475: The U.S. Census Bureau treats American Samoa's three districts and two atolls as county equivalents). American Samoa's counties are treated as minor civil divisions. Most territories are directly divided into municipalities or similar units, which are treated as equivalent of counties for statistical purposes: The U.S. Census Bureau counts all of Guam as one county equivalent (with the FIPS code 66010), while
15300-683: The U.S. Census Bureau. The number of counties per state ranges from the three counties of Delaware to the 254 counties of Texas . County populations also vary widely: in 2017, according to the Census Bureau, more than half the U.S. population was concentrated in just 143 of the more than 3,000 counties, or just 4.6% of all counties; the five most populous counties, ordered from most to least, are Los Angeles County, California ; Cook County, Illinois ; Harris County, Texas ; Maricopa County, Arizona ; and San Diego County, California . As of 2022 , there are 3,144 counties and county-equivalents in
15480-613: The U.S. government and the Native Americans involving their relocation onto a reservation in the Sierra foothills; this promise was broken. Therefore, in 1863, the tribes from the area surrounding the middle Sacramento and Feather rivers , the Konkow group, were removed and marched forcibly to the Round Valley Indian Reservation near the Eel River . A total of 461 people were forced from their homes, but only 277 made it to
15660-484: The United States is the city and county of Broomfield, Colorado , established in 2001 as a consolidated city-county , previously part of four counties. The newest county equivalents are the Alaskan census areas of Chugach and Copper River , both established in 2019, and the Alaskan boroughs of Petersburg established in 2013, Wrangell established in 2008, and Skagway established in 2007. A consolidated city-county
15840-479: The United States, Sutter and other large landholders in California held on to their properties. In 1848 Sutter assigned James W. Marshall to build a sawmill on the South Fork American River at Coloma , where Marshall discovered gold. Although Sutter and Marshall originally intended to keep the find a secret, news soon broke attracting three hundred thousand hopefuls from all over North America, and even
16020-421: The Yolo Bypass in the rice field floodplains adjacent to the Sacramento River. The name comes from a form of Japanese sushi which contains a slice of fish on top of a compressed wedge of vinegared rice. Salmon migrate from the Central Valley rivers to the ocean where they increase in size for one to three years then return to rivers to spawn, if a young fish is larger when they enter the ocean, they will have more of
16200-423: The age of 18 living with them, 51.7% were married couples living together, 10.1% had a female householder with no husband present, and 34.1% were non-families. 28.6% of all households were made up of individuals, and 12.8% had someone living alone who was 65 years of age or older. The average household size was 2.35 and the average family size was 2.87. In the county, the population was spread out, with 24.0% under
16380-461: The age of 18, 6.7% from 18 to 24, 22.7% from 25 to 44, 28.4% from 45 to 64, and 18.1% who were 65 years of age or older. The median age was 43 years. For every 100 females there were 96.5 males. For every 100 females age 18 and over, there were 94.1 males. The median income for a household in the county was $ 29,530, and the median income for a family was $ 36,890. Males had a median income of $ 31,936 versus $ 22,650 for females. The per capita income for
16560-524: The ancient path of the Siskiyou Trail, in the 1880s and 1890s. Many parts of the railroad were treacherous, especially in the mountainous areas north of Dunsmuir . It was not long after Sacramento surpassed a population of 10,000, then the Great Flood of 1862 swept away much of it (and almost everything else along the Sacramento River) and put the rest under water. The flood waters were exacerbated by
16740-549: The area, and relied on Native American labor to maintain his domain. Sutter had something of a two-faced relationship with the many Native American groups in the area. He was friendly with some of the tribes, and paid their leaders handsomely for supplying workers, but others he seized by force to labor in the fields. After the Bear Flag Revolt of 1846 and the Mexican–American War , in which California became part of
16920-537: The base of the Montezuma Hills , forming the border of Solano and Sacramento Counties. This part of the river is dredged for navigation by large oceangoing vessels and averages three-quarters of a mile (1.2 km) across. North of Antioch and Pittsburg , the Sacramento and San Joaquin Rivers join at the head of Suisun Bay , marking the official end of both rivers. The combined waters flow west through Suisun Bay and
17100-402: The board. These positions may include county clerk , county treasurer , county surrogate, sheriff , and others. District attorneys or state attorneys are usually state-level as opposed to county-level officials, but in many states, counties and state judicial districts have coterminous boundaries. The site of a county's administration, and often the county courthouse , is generally called
17280-565: The border of California and Nevada . The basin's diverse geography ranges from the glacier-carved, snowcapped peaks of the Sierra Nevada to the sea-level (and often lower) marshes and farmlands of the Sacramento-San Joaquin Delta. The highest point is 14,104 feet (4,299 m) at Mount Shasta , a dormant stratovolcano near the headwaters of the Sacramento River. The Sierra Nevada peaks generally decrease in height from south to north—from over 10,000 feet (3,000 m) in
17460-430: The bypass recorded an average throughput of 4,809 cubic feet per second (136.2 m /s) between 1939 and 2013, mostly from December–March. The highest recorded flow was 374,000 cubic feet per second (10,600 m /s) on February 20, 1986. During the dry season of July through September, the bypass carries low to zero flow. Although the Sacramento River nominally begins near Mount Shasta, the true hydrological source of
17640-501: The center of an agricultural empire that provided food to feed the thousands of miners working in the hills as well as a place of financial exchange of all the gold that was mined. Sacramento was officially established in 1850 and was recognized as the state capital in 1854. As the economy of the Sacramento Valley grew, the Southern Pacific Railroad established tracks along the river to connect California with Oregon following
17820-453: The center of the county, to lakes and dense forests, as well as desert, chaparral, and memorable waterfalls, the county is home to world-famous trout-fishing rivers and streams, such as the Sacramento and McCloud rivers. The county is dotted as well with lakes and reservoirs, such as Castle Lake and Lake Siskiyou . Mount Shasta itself has a winter sports center. Pastoral Scott Valley in
18000-410: The city and the county at least nominally exist, they are properly classified as counties in their own right. Likewise, the boroughs of New York City are coextensive with counties and are therefore by definition also not county equivalents. There are technically no counties in U.S. territories. American Samoa has its own counties , but the U.S. Census Bureau does not treat them as counties (instead,
18180-563: The confluence of North, Middle and South Forks in the Trinity Mountains of Siskiyou County . It flows east into a small reservoir, Lake Siskiyou , before turning south. The river flows through a canyon for about 60 miles (97 km), past Dunsmuir and Castella , before emptying into Shasta Lake near Lakehead in Shasta County . The McCloud River rises on the east slope of Mount Shasta and flows south for 77 miles (124 km) through
18360-503: The counties. Many of the mountainous regions of the watershed are administered by the U.S. Forest Service . The Sacramento River watershed includes large areas of coniferous forests in the Mendocino and Trinity National Forests in the Coast Ranges, Shasta and Lassen National Forests in the southern Cascades and the Plumas , Tahoe and Eldorado National Forests on the western slopes of
18540-421: The county (which merely implements state law). A typical criminal defendant will be arraigned and subsequently indicted or held over for trial before a trial court in and for a particular county where the crime occurred, kept in the county jail (if he is not granted bail or cannot make bail), prosecuted by the county's district attorney, and tried before a jury selected from that county. But long-term incarceration
18720-611: The county in Medford, Oregon , Crater Lake–Klamath Regional Airport , northeast of the county in Klamath Falls, Oregon , and Redding Municipal Airport south of the county in Redding, California . Siskiyou is a strongly Republican county in Presidential and congressional elections. The last Democrat to win a majority in the county was Lyndon Johnson in 1964 ; however, Bill Clinton won
18900-617: The county is densely forested with pine , fir , incense-cedar , oak , and madrone ; Siskiyou County is also home to the rare Baker's Cypress Tree, Cupressus bakeri , which grows in only eleven scattered locations in the world, five of which are in Siskiyou County. The county's natural resources are most often used these days for skiing, snowboarding, hiking , mountain biking , camping , and wilderness recreation, as historic logging practices have been largely discontinued due to Federal and State environmental regulations. The county's water
19080-457: The county jail.) In several southern states, public school systems are organized and administered at the county level. As of 2024 , there were 2,999 counties, 64 Louisiana parishes , 19 organized boroughs and 11 census areas in Alaska, 9 Councils of Government in Connecticut, 41 independent cities , and the District of Columbia for a total of 3,144 counties and county equivalents in
19260-495: The county was $ 17,570. About 14.0% of families and 18.6% of the population were below the poverty line , including 26.6% of those under age 18 and 7.3% of those age 65 or over. The population ranking of the following table is based on the 2020 census of Siskiyou County. † county seat County (United States) In the United States , a county or county equivalent is an administrative or political subdivision of
19440-500: The delta of the Sacramento and San Joaquin Rivers. However, due to their vantage point, neither Fages nor any of his men saw the Sacramento clearly. They assumed that the San Joaquin, coming from the south, was the largest of the merging rivers they saw. In 1808, explorer Gabriel Moraga , on a journey to find suitable sites for the construction of missions, became the first foreigner to see the river clearly. Judging its huge breadth and power he named it Rio de los Sacramentos , or "River of
19620-596: The east. A few miles downstream it forms the border of Butte County and Glenn County to the west. Stony Creek joins from the west in Glenn County, near Hamilton City and about 15 miles (24 km) west of Chico . The river then forms the Glenn– Colusa County line for a short distance before crossing entirely into Colusa County. It passes by the Sutter Buttes , a group of volcanic hills that rise abruptly from
19800-536: The eastern boundary of the Yolo Bypass . The manually operated Sacramento Weir, located across from downtown Sacramento on the west side of the river, serves to relieve floodwater pressure from the American River by allowing it to drain west into the Yolo Bypass instead of continuing down the Sacramento River. Downstream of Sacramento, the river enters the Sacramento–San Joaquin River Delta ,
19980-399: The four independent municipalities within its borders: Atlantic Beach , Baldwin , Jacksonville Beach , and Neptune Beach . The term county equivalents is used by the United States Census Bureau to describe divisions that are comparable to counties but called by different names: Consolidated city-counties are not designated county equivalents for administrative purposes; since both
20160-461: The general law of the state or by a charter specific to that county. States may allow only general-law counties, only charter counties, or both. Generally, general-law local governments have less autonomy than chartered local governments. Counties are usually governed by an elected body, variously called the county commission , board of supervisors , commissioners' court , county council , county court , or county legislature . In cases in which
20340-622: The geographically largest cities in the world, though often with population densities far below those of most urban areas. There are 40 consolidated city-counties in the U.S., including Augusta–Richmond County; the City and County of Denver, Colorado; the City and County of Honolulu, Hawaii ; Indianapolis–Marion County, Indiana ; Jacksonville–Duval County, Florida ; Louisville–Jefferson County, Kentucky ; Lexington–Fayette County, Kentucky ; Kansas City–Wyandotte County, Kansas ; Nashville–Davidson County, Tennessee ; New Orleans–Orleans Parish, Louisiana ;
20520-517: The geographically similar Colusa Basin is located to the west. The Sutter Bypass begins at Colusa and runs parallel to the east side of the Sacramento River until reaching the confluence with the Feather River . The Yolo Bypass, located on the west side of the river, starts at the confluence of the Feather and rejoins the Sacramento in the Delta. Although termed "bypasses", the system essentially reconnects
20700-425: The gold fields. As the miners expanded their diggings deeper into the Sierra Nevada and Klamath Mountains, Native Americans were pushed off their land and a long series of skirmishes and fights began that continued until intervention by the state and national governments. The influx of migrants brought foreign diseases like malaria and smallpox , which American Indians had no immunity to. These diseases killed off
20880-426: The gold fields. By the late part of the century mining had ceased to be a major part of the economy, and many immigrants turned to farming and ranching. Many populous communities were established along the Sacramento River, including the state capital of Sacramento . Intensive agriculture and mining contributed to pollution in the Sacramento River, and significant changes to the river's hydrology and environment. Since
21060-597: The headwaters of the American River near Lake Tahoe , to 5,000 to 7,000 feet (1,500 to 2,100 m) in Lassen County where they adjoin the Cascade Range. On the west side, the Coast Ranges are the opposite, increasing in height to almost 10,000 feet (3,000 m) in the north. The arid volcanic plateaus in the northeast, which are characterized by alternating hills and large sedimentary basins, typically lie at elevations of 3,000 to 5,000 feet (910 to 1,520 m). Most of
21240-405: The judicial branch of the state government rather than county governments. In many states, the county controls all unincorporated lands within its boundaries. In states with a township tier, unincorporated land is controlled by the townships. Residents of unincorporated land who are dissatisfied with county-level or township-level resource allocation decisions can attempt to vote to incorporate as
21420-1038: The land in the delta to gradually sink since the late 19th century. Many of the delta islands would be underwater if not for the maintenance of the levees and pumps that keep them dry. Some of the "islands" are now up to 25 feet (7.6 m) below the adjacent channels and sloughs. The Sacramento River watershed is home to about 2.8 million people; more than two-thirds live within the Sacramento metropolitan area . Other important cities are Chico , Redding , Davis and Woodland . The Sacramento River watershed covers all or most of Shasta , Tehama , Glenn , Butte , Plumas , Yuba , Sutter , Lake and Yolo Counties. It also extends into portions of Siskiyou , Modoc , Lassen , Lake (in Oregon), Sierra , Nevada , Placer , El Dorado , Sacramento , Solano and Contra Costa Counties. The river itself flows through Siskiyou, Shasta, Tehama, Butte, Glenn, Colusa, Sutter, Yolo, Sacramento, Solano and Contra Costa, often forming boundaries between
21600-538: The land was probably submerged under the Pacific), they were worn by erosion , and the present-day range only formed about 4 million years ago. The northern part of the Sacramento watershed is more ancient, and was formed by intense volcanic activity over 25 million years ago, resulting in lava flows that covered and created the Modoc Plateau, through which the Pit River flows. Mount Shasta and Lassen Peak are among
21780-471: The land. Most of the villages were small. Although it was once commonly believed that the original natives lived as tribes , they actually lived as bands , family groups as small as twenty to thirty people. The Sacramento Valley was first settled by humans about 12,000 years ago, but permanent villages were not established until about 8,000 years ago. Historians have organized the numerous separate original native groups into several "tribes". These are known as
21960-476: The largest irrigation projects in the world, was constructed by the U.S. Bureau of Reclamation beginning in 1935. Ultimately, the system would distribute 7 million acre-feet (8.6 km ) to irrigate 3 million acres (1.2 million ha) of land in the Sacramento and San Joaquin Valleys. Construction of Shasta Dam, the principal water storage facility in the Sacramento River system, started in 1938 and
22140-550: The late 1700s. The Spanish explorer Gabriel Moraga named the river Rio de los Sacramentos in 1808, later shortened and anglicized into Sacramento . In the 19th century, gold was discovered on a tributary of the Sacramento River, starting the California Gold Rush and an enormous population influx to the state. Overland trails such as the California Trail and Siskiyou Trail guided hundreds of thousands of people to
22320-560: The least extensive county equivalent is Kingman Reef , with a land area of 0.01 square miles (0.03 km ). In some states, a municipality may be in only one county and may not annex territory in adjacent counties, but in the majority of states, the state constitution or state law allows municipalities to extend across county boundaries. At least 32 states include municipalities in multiple counties . Dallas , for example, contains portions of five counties, while numerous other cities comprise portions of four counties. New York City
22500-416: The legislative power to enact laws for the county; it has the executive power to oversee the executive operations of county government; and it has quasi-judicial power with regard to certain limited matters (such as hearing appeals from the planning commission if one exists). In many states, several important officials are elected separately from the board of commissioners or supervisors and cannot be fired by
22680-543: The lower end of Shasta Lake is Shasta Dam , which impounds the Sacramento River for flood control, irrigation and hydropower generation. Before the construction of Shasta Dam, the McCloud River emptied into the Pit River, which joined the Sacramento near the former mining town of Kennett , submerged when Shasta Lake was filled. The Pit River Bridge , which carries Interstate 5 and the Union Pacific Railroad over
22860-529: The main channel of the Sacramento. The Sacramento River and the Sutter Bypass flow parallel for over 40 miles (64 km), rejoining on the border of Sutter County and Yolo County near Knights Landing . The Feather River , the largest tributary of the Sacramento, joins from the east at Verona directly below the Sutter Bypass. A second flood control structure, the Fremont Weir, diverts flood waters from both
23040-674: The matter to the states. Subsequently, state constitutions conceptualized county governments as arms of the state. Louisiana instead adopted the local divisions called parishes that dated back to both the Spanish colonial and French colonial periods when the land was dominated by the Catholic Church . In the twentieth century, the role of local governments strengthened and counties began providing more services, acquiring home rule and county commissions to pass local ordinances pertaining to their unincorporated areas . In 1955, delegates to
23220-614: The middle of the Sacramento Valley, where it receives Butte Creek from the east at Colusa . Below Colusa the river flows south-southeast, forming the border of Colusa County and Sutter County to the east. About 20 miles (32 km) further downstream, the Sacramento River reaches the Tisdale Weir. During floods, water overtops the weir and flows east into the Sutter Bypass , the first of two major bypass channels that temporarily store and move floodwaters downstream to reduce pressure on
23400-515: The most productive agricultural area in the nation, these changes have left the Sacramento greatly modified from its natural state and have caused the decline of its once-abundant fisheries. The Sacramento River originates in the mountains and plateaus of far northern California as three major waterways that flow into Shasta Lake : the Upper Sacramento River, McCloud River and Pit River . The Upper Sacramento begins near Mount Shasta , at
23580-413: The most recent being the Great Flood of 1862 . Dams, levees and floodways constructed during the 20th century have thus far prevented this phenomenon from re-occurring. The Sacramento River and its valley were one of the major Native American population centers of California. The river's abundant flow and the valley's fertile soil and mild climate provided enough resources for hundreds of groups to share
23760-514: The next most common source of county names are geographic features and locations, with some counties even being named after counties in other states, or for places in other countries, such as the United Kingdom (the latter is most common in the area of the original Thirteen Colonies in the case of the United Kingdom, or in places which had a large number of immigrants from a particular area for other countries). The most common geographic county name
23940-576: The numerous Cascade Range volcanoes that still stand in the area. As the Sierra rose, water erosion and glaciation carved deep canyons, depositing massive amounts of sediment to form a coastal plain between the mountains and the Pacific Ocean. About 3 million years ago, multiple terranes were formed and smashed into the North American Plate from the Pacific Plate, causing the uplift of
24120-424: The official record of all real estate transactions. Other key county officials include the coroner / medical examiner , treasurer , assessor , auditor , comptroller , and district attorney . In most states, the county sheriff is the chief law enforcement officer in the county. However, except in major emergencies where clear chains of command are essential, the county sheriff normally does not directly control
24300-462: The one hand, and to ensure a consistent supply of water on the other. The U.S. Army Corps of Engineers and the State of California completed reports as early as the 1870s and 1880s which outlined future development of the Sacramento, Feather, Yuba and Bear rivers. In 1873, Colonel B.S. Alexander of the Army Corps of Engineers surveyed the Central Valley's hydrology and irrigation systems and proposed
24480-626: The parasitic cowbird , which lays its eggs in the nests of other bird species causing its hatchlings to compete with the others for food. There were once 9 species of amphibians that used the Sacramento River, but some have become extinct and most other populations are declining due to habitat loss caused by agriculture and urban development. Amphibians originally thrived in the marshes, sloughs, side-channels and oxbow lakes because of their warmer water, abundance of vegetation and nutrients, lower predator populations and slower current. This population once included several species of frogs and salamanders;
24660-410: The period 1945–2013. The McCloud River had an average discharge of 775 cu ft/s (21.9 m /s) for the 1967–2013 period. Since the 1960s, the McCloud River flow has been reduced and the Pit River flow increased due to diversion of water for hydropower generation; however the total volume of water entering Shasta Lake remains the same. Before Shasta Dam was built, the volcanic springs feeding
24840-448: The police departments of city governments, but merely cooperates with them (e.g., under mutual aid pacts). Thus, the most common interaction between county and city law enforcement personnel is when city police officers deliver suspects to sheriff's deputies for detention or incarceration in the county jail. In most states, the state courts and local law enforcement are organized and implemented along county boundaries, but nearly all of
25020-454: The population were Hispanic or Latino of any race. 13.5% were of German , 12.0% English , 9.8% Irish , 9.5% American and 7.1% Italian ancestry according to Census 2000 . 91.7% spoke English and 5.7% Spanish as their first language. As of March 2012, the largest self-reported ancestry groups in Siskiyou County are 15% German , 13% English , 12% Irish and 6% Italian . There were 18,556 households, out of which 27.6% had children under
25200-411: The precipitation." The topography of the Sacramento River watershed makes it particularly prone to flooding. Storm water runs quickly off the steep mountains flanking the Sacramento Valley, but with few exceptions the alluvial valley floor is strikingly flat, slowing down the runoff and causing it to overflow the river banks. Before flood control works were built, the winter floods frequently transformed
25380-478: The pressure of floodwaters on the main channel. The bypasses are then allowed to drain slowly once flood crests have passed. For most of the year, the bypasses remain dry and are used for annual crops such as rice. Some of the principal features are the Butte Basin, Colusa Basin, Sutter Bypass and the Yolo Bypass. The Butte Basin is a large lowland area on the east side of the river between Hamilton City and Colusa ;
25560-479: The principal river of Northern California in the United States and is the largest river in California. Rising in the Klamath Mountains , the river flows south for 400 miles (640 km) before reaching the Sacramento–San Joaquin River Delta and San Francisco Bay . The river drains about 26,500 square miles (69,000 km ) in 19 California counties , mostly within the fertile agricultural region bounded by
25740-694: The range for California Buckeye , a widespread California endemic. The Klamath National Forest occupies 1,700,000 acres (6,900 km) of land which includes elements in Siskiyou County as well as Jackson County, Oregon . Siskiyou Transit And General Express (STAGE) operates buses connecting the more populated areas of the county. Amtrak trains stop in Dunsmuir . Amtrak Thruway formerly operated between Sacramento and Medford, OR, with stops in Yreka, Weed, Mount Shasta, and Dunsmuir, for passengers connecting to and from Amtrak trains in Sacramento or Stockton; this service
25920-462: The rate per 1,000 persons for each type of offense. The 2010 United States Census reported Siskiyou County had a population of 44,900. The racial makeup of Siskiyou County was 38,030 (84.7%) White , 571 (1.3%) African American , 1,814 (4.0%) Native American , 540 (1.2%) Asian , 80 (0.2%) Pacific Islander , 1,491 (3.3%) from other races , and 2,374 (5.3%) from two or more races. Hispanic or Latino of any race were 4,615 persons (10.3%). As of
26100-578: The relationship between counties and incorporated cities. The powers of counties arise from state law and vary widely. In Connecticut and Rhode Island , counties are geographic entities, but not governmental jurisdictions. At the other extreme, Maryland counties and the county equivalent City of Baltimore handle almost all services, including public education , although the state retains an active oversight authority with many of these services. Counties in Hawaii also handle almost all services since there
26280-436: The reservation; the others perished of disease, starvation or exhaustion. As mining developed from simple methods such as panning and sluicing to a new form of commercialized extraction, hydraulic mining , profits from the petering gold rush made a second leap, earning more profits than placer miners in the early years had ever made. The city of Sacramento , founded on the original site of Sutter's fort, began to flourish as
26460-550: The reservoir, is structurally the highest double-decked bridge in the United States (although most of the bridge piers are submerged under Shasta Lake when the reservoir is full). The Upper Sacramento River canyon also provides the route for I-5 and the railroad between Lakehead and Mount Shasta. Below Shasta Dam the Sacramento River enters the foothills region of the northern Sacramento Valley. It flows through Keswick Dam , where it receives about 1,200,000 acre⋅ft (1.5 × 10 million km ) of water per year diverted from
26640-473: The rice fields under the Yolo Bypass next to Sacramento River can serve as an important floodplain habitat and feeding ground for juvenile or endangered fish. UC Davis noted juveniles grew much bigger and faster within the flooded rice fields when compared to those released in the Sacramento River. Public agencies, conservation groups and landowners have all been working together and conducting experiments since 2011. Experiments conducted on rice fields took place at
26820-491: The rich valley bottom and marsh lands. Before European contact, the indigenous population of the Sacramento Valley has been estimated at 76,000 people. The first outsiders to see the river were probably the members of a Spanish colonial-exploratory venture to Northern California in 1772, led by Captain Pedro Fages . The group ascended a mountain, likely in the hills north of Suisun Bay , and found themselves looking down at
27000-403: The river after use) are about 4.72 million acre-feet (5.82 km ) for irrigation and 491,000 acre-feet (0.606 km ) for urban use. An additional 7.61 million acre-feet (9.39 km ) is reserved for environmental uses, primarily to maintain a minimum fresh water outflow in the Delta to combat salinity. The U.S. Geological Survey (USGS) has stream gauges on 25 locations along
27180-500: The river continues south it approaches the Sacramento metro area, the largest population center in the watershed. Sacramento International Airport is located on the east bank of the river near Fremont. Near downtown Sacramento it receives the American River from the east, then passes under the historic Tower Bridge and Interstate 80 Business . The California State Capitol sits less than zero point five miles (0.80 km) east of
27360-463: The river flooded up to 650,000 cubic feet per second (18,000 m /s) during the rainy season, equal to the flow of the Mississippi River . Late summers of particularly dry years could see flows drop below 1,000 cubic feet per second (28 m /s). Large volumes of water are withdrawn from the Sacramento River for irrigation, industry and urban supplies. Annual depletions (water not returned to
27540-415: The river from the lowlands to the east and west that once served as vast overflow basins during winter storms, creating large areas of seasonal wetlands . Since the 19th century, artificial levee systems have been constructed to enable farming in the fertile flood plain. Today there are 2,000,000 acres (8,100 km ) of irrigated farmland in the Sacramento Valley. Due to the reduction of the floodplain area,
27720-521: The river where the Tower Bridge crosses it. Shortly downstream, the Port of Sacramento is located on the west side of the Sacramento, connected to the river by a lock. The Sacramento River Deep Water Ship Channel provides access to the port from the Pacific, bypassing about 42 miles (68 km) of the winding lower Sacramento. The channel runs parallel to the Sacramento several miles to the west, and also forms
27900-493: The sediments washed down by the millions of tons by hydraulic mining, which filled the beds of the Sacramento, Feather and American rivers up to 7 feet (2.1 m) in Sacramento and also covered thousands of acres of Central Valley lands. A flood in 1875 covered the city of Marysville and when it subsided the town's streets were filled with debris and rocks washed down from the "hydraulicking" going on upstream. Repeated floods and increased demand for Sacramento River water saw
28080-597: The southern Cascade Range , roughly parallel to the Upper Sacramento, eventually to reach the McCloud Arm of Shasta Lake. The Pit River, by far the largest of the three, begins in Modoc County in the northeastern corner of California. Draining a vast and remote volcanic highlands area, it flows southwest for nearly 300 miles (480 km) before emptying into Shasta Lake near Montgomery Creek . Goose Lake , straddling
28260-509: The southernmost large runs of chinook salmon in North America. For about 12,000 years, humans have depended on the vast natural resources of the watershed, which had one of the densest Native American populations in California. The river has provided a route for trade and travel since ancient times. Hundreds of tribes sharing regional customs and traditions have inhabited the Sacramento Valley, first coming into contact with European explorers in
28440-796: The specific governmental powers of counties may vary widely between the states, with many providing some level of services to civil townships , municipalities , and unincorporated areas . Certain municipalities are in multiple counties ; New York City is uniquely partitioned into five counties, referred to at the city government level as boroughs . Some municipalities have been consolidated with their county government to form consolidated city-counties , or have been legally separated from counties altogether to form independent cities . Conversely, counties in Connecticut and Rhode Island , eight of Massachusetts's 14 counties , and Alaska's Unorganized Borough have no government power, existing only as geographic distinctions. The United States Census Bureau uses
28620-499: The speed of flood flow in the Sacramento River has increased, creating a significant hazard for the farms and towns along its course. By the early 20th century engineers had realized not all the floodplains could be safely reclaimed, leading to the intentional creation of flood bypasses where development is limited to annual crops and recreational uses. Further south, much of the delta region is actually below sea level: subsidence caused by wind erosion and intensive farming have caused
28800-541: The state's French and Spanish colonial periods. Before the Louisiana Purchase and granting of statehood, government was often administered in towns where major church parishes were located. Of the original 19 civil parishes of Louisiana that date from statehood in 1807, nine were named after the Roman Catholic parishes from which they were governed. The structure and powers of a county government may be defined by
28980-421: The substantive and procedural law adjudicated in state trial courts originates from the state legislature and state appellate courts. In other words, most criminal defendants are prosecuted for violations of state law, not local ordinances, and if they, the district attorney, or police seek reforms to the criminal justice system, they will usually have to direct their efforts towards the state legislature rather than
29160-399: The term "county equivalent" to describe places that are comparable to counties, but called by different names. Louisiana parishes, the organized boroughs of Alaska, independent cities, and the District of Columbia are equivalent to counties for administrative purposes. Alaska's Unorganized Borough is further divided into 11 census areas that are statistically equivalent to counties. In 2024,
29340-418: The valley into an inland sea. In 1880 State Engineer William H. Hall developed the first flood control plan for the Sacramento River. Hall recognized that with the combination of flat topography and extremely heavy winter runoff volumes, a system of levees alone could not hope to contain flooding, as had been proven time and again in the flood prone city of Sacramento. The Sacramento River Flood Control Project
29520-480: The water stays fresh in all but the driest years. Saltwater intrusion from the Pacific Ocean was one of the main reasons for the construction of the federal Central Valley Project (CVP), whose dams maintain a minimum flow in the Sacramento River to keep seawater at bay. Below Rio Vista , the lower Sacramento River is rejoined by the Deep Water Ship Channel and the Yolo Bypass and curves southwest along
29700-634: The watershed. By geologic standards, the Sacramento is a fairly young river; the borders of its watershed began to form only a few million years ago as magma welling up below the Earth's crust pushed up by the Pacific Plate colliding with the North American Plate caused the formation of the Sierra Nevada . Although mountains had existed as early as 100 million years ago in this region (before then
29880-422: The western part of the county has many wide, tree-lined meadows, supporting large cattle ranches. The basins of northeastern Siskiyou County, including Butte Valley, Lower Klamath and Tule Lake basins, have some of the deepest and richest soils in the state, producing alfalfa, potatoes, horseradish, and brewing barley. Butte Valley nurseries are the leading source of premium strawberry plants in North America. Much of
30060-517: The world, to the Sacramento River in search of fortunes, kicking off the California Gold Rush . People flocked to the region by the Oregon Trail -Siskiyou Trail, California Trail , Southern Emigrant Trail and various land and/or sea routes through the Isthmus of Panama and around southern South America by ship. Steamboats traveled up and down the Sacramento River carrying miners from San Francisco to
30240-431: The years to come, this path, which eventually extended from San Francisco to Portland, Oregon following parts of the Sacramento, Willamette , Klamath , Rogue , and other rivers would become an important trade and travel route. Although just one of thousands of American emigrants that poured into California over the next few years when California became part of the United States, John Augustus Sutter 's arrival marked
30420-473: Was 23,330 cubic feet per second (661 m /s). The maximum recorded flow was 115,000 cubic feet per second (3,300 m /s) on February 19, 1986; the lowest was 3,970 cubic feet per second (112 m /s) on October 15, 1977. Flow in the Yolo Bypass , a relief channel designed to carry a portion of the flood waters in order to protect the Sacramento area, is not measured by the Freeport gauge. A separate gauge on
30600-522: Was at least 1,000 feet (300 m) deep. About 650,000 years ago the lake catastrophically overflowed, draining into San Francisco Bay and creating the Carquinez Strait , the only major break for hundreds of miles in the Coast Ranges. The narrow outlet trapped some of the sediments of the rivers in the Central Valley, forming the inland Sacramento-San Joaquin River Delta . Since then, this inland sea has periodically reformed during times of intense flooding,
30780-416: Was authorized by the federal government in 1917. While it intended to contain minor floods in the river banks by strengthening the existing levee system, the main feature was a series of bypasses, or sections of the valley intentionally designed to flood during high water. Weirs placed at strategic points along the Sacramento River release water into the bypasses when the river reaches a certain stage, relieving
30960-465: Was completed in 1945. Controlling runoff from the upper 6,600 square miles (17,000 km ) of the Sacramento River watershed, Shasta greatly reduces flood peaks on the middle and lower parts of the Sacramento River. Flood waters are stored for irrigation in dry years as well as navigation and electricity generation. In the following decades, more huge reservoirs – capable of storing a combined 13 × 10 acre-feet (16 km ) of water – were constructed on
31140-400: Was completed in 1963, and was built to facilitate navigation of large oceangoing ships from the Delta to the port of Sacramento. The channel bypasses the winding lower part of the Sacramento River between the state capital and the Delta thus reducing water travel times. It also serves to discharge floodwaters from the lower end of the Yolo Bypass . Built by the Army Corps of Engineers, the canal
31320-434: Was crucial to the renewal of existing wetlands and the creation of new ones. Since the late 19th century the river has been mostly locked in a fixed channel, which once could shift hundreds of feet or even several miles in a year because of floods. In 2010, about 100 miles (160 km) of the river's riparian forests were undergoing restoration. UC Davis initiated a project known as The Nigiri Project which takes place under
31500-498: Was discontinued in 2009. Greyhound buses pass through the county on Interstate 5 with a stop in Weed. Siskiyou County owns and operates Butte Valley Airport , Happy Camp Airport , Scott Valley Airport , Siskiyou County Airport and Weed Airport (all general aviation). Dunsmuir Municipal-Mott Airport and Montague-Yreka Rohrer Field are also within the county. The closest airports for commercial domestic plane departures are Rogue Valley International-Medford Airport north of
31680-440: Was dissolved by the District of Columbia Organic Act . Jefferson County , for Thomas Jefferson , is next with 26. The most recent president to have a county named for him was Warren G. Harding , reflecting the slowing rate of county creation since New Mexico and Arizona became states in 1912. The most common names for counties not named after a president are Franklin (25), Clay (18), and Montgomery (18). After people,
31860-417: Was extended by Hudson's Bay Company trappers in the 1830s. Its length was increased by " Forty-Niners " during the California gold rush . After the discovery of an important gold strike near today's Yreka, California , in 1851, prospectors flooded the area. This was described in detail by Joaquin Miller in his semi-autobiographical novel Life Amongst the Modocs. In the mid-1880s, the construction of
32040-643: Was practiced in a few areas. Settlement size ranged from small camps to villages of 30–50 permanent structures. Acorns were a staple food , and the Sacramento Valley's riparian zones, which supported seven species of native oaks, provided these in abundance. Native Americans pounded the acorns into flour, which they used to make bread and cakes. Abundant salmon and steelhead runs in the Sacramento River and its tributaries were harvested using fishing weirs, platforms, baskets and nets. The river also provided shellfish, sturgeon, eel and suckerfish They also hunted waterfowl, antelope and deer which all existed in huge numbers in
32220-404: Was the Trinity River Project (which would become part of the CVP), sending over 90 percent of the flow of that river into the Sacramento via a tunnel under the Klamath Mountains. Due to environmental damage and fish kills in the Trinity River, the volume of diverted water has been limited by law since the 1990s. Other, larger projects ultimately failed to take root. One of the most notorious,
32400-407: Was under the control of Mexico , although few Mexican settlers had come to what would later become the state, mostly settling in the small pueblos and ranchos along the south and central coast. The HBC mountain men created the Siskiyou Trail out of several Native American paths that ran through the mountains between Oregon's Willamette Valley and the northern part of the Sacramento Valley.
