The Eel River forms a 7-mile (11 km) long estuary west of Fortuna, which has been identified as one of the most important and sensitive estuaries on the West Coast. The estuary consists of some 8,700 acres (3,500 ha) of tidal flats, perennial and seasonal wetlands, connected by 75 miles (121 km) of river channels and tidal sloughs . About 1,550 acres (630 ha) consist of undeveloped wetlands while 5,500 acres (2,200 ha) have been converted to agriculture. The estuary
1080-892: A run of over 30,000 fish, the largest on record since 1958. Since 2012, runs have fluctuated. While improved from the low point of 3,500 at the beginning of the decade, the runs have yet to again reach the high mark of over 30,000. From 2013 to 2014, 2016 to 2017 were between 15,000 and 25,000 while 2015, and 2018 to 2019 were between 9,000 and 15,000. The river provides wildlife habitat for preservation of rare and endangered species including warm and cold freshwater habitat for fish migration and spawning. The river and its tributaries support at least 15 species of native freshwater fish. Major species include Pacific lamprey , Entosphenus tridentatus , formerly Lampetra tridentata , Sacramento sucker , threespine stickleback , Pacific staghorn sculpin , Coastrange sculpin and prickly sculpin . At least 16 species of non-native fish have been introduced to

Waterfowl, bear, and other wildlife abound in the Clear Lake basin. Due to its surrounding hilly terrain, Lake is the only one of California's 58 counties never to have been served by a railroad line. In 2015 President Barack Obama created the Berryessa Snow Mountain National Monument , incorporating these and other areas. In
1404-574: Is 16 million short tons , or an average of 4,458 tons per square mile (1,720 tons/km ). Flooding events have a large effect on the average amount of transported sediment: high water in the years 1969, 1983 and 1998 caused an annual sediment load 27 times greater than that of normal years. Among rivers of the contiguous United States, only the Mississippi River carries more sediment to the sea (the Colorado River historically transported more than
1512-766: Is a major river, about 196 miles (315 km) long, in northwestern California . The river and its tributaries form the third-largest watershed entirely in California, draining a rugged area of 3,684 square miles (9,540 km ) in five counties. The river flows generally northward through the Coast Ranges west of the Sacramento Valley , emptying into the Pacific Ocean about 10 miles (16 km) downstream from Fortuna and just south of Humboldt Bay . The river provides groundwater recharge , recreation, and industrial, agricultural and municipal water supply. The Eel River system
1620-562: Is among the most dynamic in California because of the region's unstable geology and the influence of major Pacific storms. The discharge is highly variable; average flows in January and February are over 100 times greater than in August and September. The river also carries the highest suspended sediment load of any river of its size in the United States, in part due to the frequent landslides in
1728-653: Is directly north of the San Francisco Bay Area . Lake County is part of California's Wine Country , which also includes Napa , Sonoma , and Mendocino counties. It includes nine American Viticultural Areas and around 20 bonded wineries. Lake County has been inhabited by Pomo Native Americans for over ten thousand years. Pomos had been fishermen and hunters, known especially for their intricate basketry made from lakeshore tules and other native plants and feathers. Pomo people continue to live in Lake County. The area had European American settlers since at least
1836-679: Is diverted from the Eel River basin through a 1-mile (1.6 km) tunnel to the East Fork Russian River , in a scheme known as the Potter Valley Project . Below the dam the river turns north, flowing through a long, isolated valley, receiving Outlet Creek from the west and then the Middle Fork Eel River from the east at Dos Rios . About 20 miles (32 km) downstream, the North Fork Eel River –draining one of

In 2018 CalTrout , along with other partners, announced they had received a grant of over $ 5M to revive the degraded estuary. The site of the project is the Eel River Estuary Preserve, formerly known as Connick Ranch. The Wildlands Conservancy acquired the land in 2008 with the goal of restoring the wetland system and provide public access to
2700-499: Is the only cold water available in the basin during the dry season. During July, August and September, temperatures in the lower Eel River occasionally hit 85 °F (29 °C) or higher, creating fatal conditions for these fish. In 1983, the Federal Energy Regulatory Commission relicensed the project under the condition that more water be provided to the Eel River during the dry season and less be diverted to

3024-658: The Eel River , providing water and power to Ukiah in Mendocino County . Clear Lake is believed to be the oldest warmwater lake in North America , due to a geological fluke. The lake sits on a huge block of stone which slowly tilts in the northern direction at the same rate as the lake fills in with sediment , thus keeping the water at roughly the same depth. The geology of the county is chaotic, being based on Franciscan Assemblage hills. Numerous small faults are present in
3132-631: The Mad River , on the east by that of the Sacramento River , on the west by that of the Mattole River , and on the south by those of the Russian River and Ten Mile River . Major centers of population on the river include Willits , Garberville , Redway , Scotia, Rio Dell , Fortuna, and Ferndale . Minor communities include Laytonville , Branscomb , Cummings, Leggett , Piercey, Benbow , Phillipsville , Myers Flat , Shively , and Pepperwood . The river's relatively large estuary and delta, which includes

In the western and northern portions of the Eel River watershed, soils eroded from the Franciscan assemblage are often sticky, clayey and highly unstable, creating a high risk of landslides. This soil is often known as " blue goo " because of its gray-blue color, soft, sticky texture, and its tendency to slip when saturated. Further inland and south, soils are well drained, although landslides are nevertheless common because of
3348-550: The Pacific Gas and Electric Company's Potter Valley Project , located to the south in Mendocino County . Although the effect on the total annual flow is negligible (only about 3 percent of the total flow of the Eel River) the impact is much larger during the dry season, when the Eel's already-low natural flows are further reduced by diversions. Since 2004 the dams used by the project have been required to provide additional flow to

3456-569: The Sacramento–San Joaquin River Delta . The proposal was defeated with public initiative by the early 1970s, to protect the remaining relatively wild rivers in the state. Ronald Reagan , governor of California at the time, refused to approve the project. The proposed reservoir would have flooded the Round Valley Indian Reservation . In 1964, a severe Pineapple Express event known as "The '64 Flood" brought heavy rains to coastal northern California. The Eel River drainage area
3564-540: The Salt River tributary and related creeks, is located just one low ridge south from Humboldt Bay and 12 miles (19 km) south of Eureka , the main city in the region. Since the mid-19th century, logging activity in the watershed has loosened soil and destabilized aquifers, reducing the river's base flow , although the watershed is slowly recovering. Logging, grazing and other resource exploitation activities and their accompanying environmental changes have also increased
3672-612: The aerospace industry. Lake County's economy is largely driven by agriculture. The main crops in 2022 were: The first vineyards in Lake County were planted in the late 19th century, but Prohibition and its remoteness dealt a blow to the area's viticulture . A reemergence of the wine industry began in the 1970s, although most of the region's grapes are still trucked to neighboring Napa , Sonoma and Mendocino counties for vinification . The county saw its vineyard acreage increase from fewer than 100 acres (40 ha) in 1965 to more than 11,000 acres (4,500 ha) in 2023 The region

3888-442: The 1840s. Lake County was created in 1861 from parts of Napa and Mendocino counties. The eastern boundary of Lake County, which was not clearly specified in the 1861 act, was clarified by legislative acts passed in 1864 and 1868. A major effect of the 1868 act was to include in Lake County the entire watershed of North Fork Cache Creek , which had previously been claimed by Colusa County . The 1911 California Blue Book lists
3996-429: The 1850s, with multiple canneries on the Eel River operating into the early to mid 1900s. Between 1857 and 1921, canning operations took an estimated 93,000 fish per year, with a peak of 600,000 fish in 1877. By the 1890s, fish populations had already recorded a precipitous decline. Logging and grazing, which expose formerly forested land as bare ground, have had even greater impact on the populations of these fish. Due to
4104-546: The 1920s due to overfishing. The Eel River basin has also been a significant source of timber since the days of early settlement, and continues to support a major logging sector. The river valley was a major rail transport corridor for the Northwestern Pacific Railroad beginning in 1914 and continuing throughout the 20th century, and also forms part of the route of the Redwood Highway (US Highway 101). Since
4212-402: The 1964 flood, chinook salmon populations plunged to fewer than 10,000 per year. Anadromous fish populations have continued to decline since the 1960s; in 2010, only 3,500 salmon and steelhead returned to the river to spawn. However, with better land management practices in the watershed, salmon and steelhead runs have shown signs of recovery. In late 2012, high water in the Eel River attracted

Sediment deposits indicate the lake may have persisted for as many as several thousand years, which is highly unusual considering the easily eroded rock of the region and the unstable nature of landslide dams in general. The dam blocked access to steelhead trout spawning grounds in

Because the Eel River's twists and turns made it difficult to float the large redwood logs, the timber was cut into smaller rectangular "cants" to make them more manageable. In 1884 the Eel River and Eureka Railroad began shipping lumber from the Eel River estuary to the port at Humboldt Bay, where the logs were loaded onto ships bound for San Francisco. As part of

The federal United Western Investigation study in 1951 proposed multiple large dams on the wild North Coast rivers of California, including the Eel River. These dams would have been far bigger than those of

Collier's bill was supported by powerful agricultural interests in the Central Valley on the then-"dubious claim" that they would need the water from these rivers in the future. After the state legislature approved both bills,

The Army Corps of Engineers and Bureau of Reclamation both sought to build dams in the Eel River system which, starting in the 1960s was targeted as a potential new source for the California State Water Project. Major dams proposed in the watershed included ones at English Ridge, Bell Springs and Sequoia (Alderpoint) on
6156-468: The Potter Valley or Eel River Project, a pair of dams were built across the upper reaches of the Eel beginning in 1906 to divert water to the more populous but smaller Russian River drainage area to the south, resulting in a much higher flow in the smaller river and a decreased flow in the upper Eel during certain seasons. Although located near the headwaters, these dams can cause a significant reduction of

During the 1950s and 1960s, there was great interest in building much larger dams in the Eel River system, in order to provide water for the State Water Project . Although the damming would have relieved pressure on greater California's overburdened water systems, it stirred up decades of controversy, as some of

Wilson calculated that Dos Rios would have reduced the 35-foot (11 m) flood crest of the 1964 flood at Fort Seward by less than a foot (0.3 m). Governor Ronald Reagan formally refused to authorize
7560-419: The flow of the lower Eel River because much of the river's summer flow originates from the mountains above Lake Pillsbury. In 1910 noted American engineer John B. Leonard designed Fernbridge , a 1,320 feet (400 m) all-concrete arched bridge at the site of the earlier Singley's Ferry crossing. Completed in 1911, and now listed on the National Historic Register, Fernbridge is the last major crossing before
7668-416: The golden spike at Cain Rock was delayed by flooding and subsequent landslide damage to the rail line in October 1914. In the 1950s, interest grew in damming the Eel River system to provide water for central and southern California. After a damaging flood in 1955, these dams also received support for potential flood-control benefits. The U.S. Bureau of Reclamation and U.S. Army Corps of Engineers proposed
7776-543: The high rainfall and steep slopes. Because of the mountainous topography, the only flat land in the Eel River watershed is along the larger river valleys, where stream terraces have been formed, and in the estuary region near the mouth of the river. Terraces were formed due to a combination of the high sediment load of the river system, and the rapid regional rate of geologic uplift (up to 13 feet (4.0 m) per 1000 years, as measured at Scotia Bluffs). The Eel's behavior of downcutting its own sediments has caused it to flow in
7884-421: The huge amount of sediment and debris swept down the river, including millions of board feet of timber. The deepest flood waters were nearly 70 feet (21 m) above the normal river level. Several thousand people were left homeless by the floods and over 4,000 head of livestock died. The large storms of the mid-20th century, along with the ecological changes from logging and grazing activities, almost wiped out
7992-550: The intensity of flood and drought. Prior to 2011, the Eel River basin consisted of 65.1% forest, 12.2% shrubland , and 19.2% grassland , with just 1.9% agricultural and 0.2% developed urban. The human population of the watershed is about 32,000–less than 10 people per square mile (26/km ). In the 20th century, much of the watershed area was included under state parks and national forest, including Six Rivers National Forest , Yolla Bolly-Middle Eel Wilderness , and Humboldt Redwoods State Park . A total of 398 miles (641 km) of
8100-438: The largest peaks recorded in the world relative to the size of its drainage basin. In contrast, during the dry months of July through September, the river achieves nearly zero flow. The lowermost United States Geological Survey (USGS) stream gauge on the Eel where flow volume is measured is at Scotia , where an annual mean of 7,309 cubic feet per second (207.0 m /s), or 5.3 million acre-feet (6.5 km ) per year,
8208-694: The largest such trees in California. In the Eel River basin, redwoods can be found further inland than other parts of the northern California coast because of the wide lower valley of the river, which acts as a funnel conducting moist air eastward from the coast. However, redwood groves are still most common in the drainage area of the South Fork Eel River, which lies closest to the Pacific. Aquatic mammals include beaver , muskrat , raccoon , river otter and mink . Beavers are confirmed in Outlet Creek (tributary to main stem Eel north of Willits), but may occur in other areas as well. That beaver were once native to
8316-432: The late 19th century, the worldwide popularity of mineral water for the relief of myriad physical ailments resulted in the development of mineral resorts around Clear Lake. Lake County has a mediterranean climate with hot summer daytime temperatures in its lower elevations. Nighttime temperatures remain cool year-round, somewhat moderating average temperatures and relieving the summer heat. Lake County has been ranked by
8424-439: The main stem, and the infamous Dos Rios on the Middle Fork. Dos Rios Dam would have flooded 110,000 acres (45,000 ha) of Mendocino County, creating a reservoir of 7.5 million acre-feet (9.3 km )–the largest in California, at nearly twice the size of Shasta Lake . Water would have been diverted from English Ridge north to Dos Rios and through a 40-mile (64 km) tunnel to the offstream Glenn-Colusa reservoir in
8532-428: The major crops as Bartlett pears and beans. Other crops include grain, alfalfa, hay, prunes, peaches, apples, grapes and walnuts. Stockraising included goats, hogs, turkeys and dairying. Some vineyards were planted in the 1870s by European Americans, but the first in the state were established in the 18th century by Spanish missionaries. By the early 20th century, the area was earning a reputation for producing some of
8640-482: The major species. In its natural state, it was the third-largest salmon- and steelhead-producing river system in California, with over a million fish spawning annually, after the Sacramento and Klamath rivers . The annual chinook salmon run was estimated at 100,000–800,000, coho at 50,000–100,000, and steelhead may have numbered as high as 100,000–150,000. About 22,000 years ago, a massive landslide off Nefus Peak dammed
8748-457: The most rugged and remote portions of the watershed–joins from the east. Between the North and Middle Forks the Round Valley Indian Reservation lies east of the Eel River. After this confluence the Eel flows briefly through southwestern Trinity County , past Island Mountain , before entering Humboldt County near Alderpoint . The river cuts in a northwesterly direction across Humboldt County, past
8856-401: The mountainous terrain and heavy precipitation in the Eel River watershed, erosion rates are particularly high. Much of the anadromous fish spawning habitat in the river system was covered by sediment or blocked by debris jams. Record flooding in 1955 and 1964, which destroyed or damaged large amounts of habitat along the Eel and its tributaries, was generally regarded as the final blow. After
8964-404: The project. Despite Reagan's veto, the door to Eel River dams technically remained open. In early 1972, California state senator Peter H. Behr introduced a measure to create a state wild and scenic rivers system, which would protect many undeveloped North Coast rivers, including the Eel, from future damming. In the same year, senator Randolph Collier proposed a measure that would block dams in
9072-403: The proposals made little economic sense and would have been detrimental to an ailing salmon run. The Eel was granted federal Wild and Scenic River status in 1981, formally making it off-limits to new dams. Nevertheless, logging, grazing, road-building, a burgeoning cannabis industry, and other human activities continue to significantly affect the watershed's ecology. The Eel River originates on
9180-407: The protection of California's remaining wild rivers. The great floods of 1955 and 1964 brought renewed interest in building large dams on the Eel River, especially in the case of the Army Corps of Engineers, which attempted to justify the construction of Dos Rios for flood control. However, among all the proposed dams on the Eel River, Dos Rios would have the lowest impact on flood control–a fact that
9288-428: The rediscovery of Humboldt Bay by land. The bay had been seen by earlier Spanish and Russian explorers but never settled. After camping and restocking at Humboldt Bay, they traveled to San Francisco to report their discovery. They crossed the Eel River on their way south where they traded a broken frying pan to the local fishermen in exchange for a large number of Pacific lamprey, which they mistook for eels. They named
9396-622: The region. However, the river basin also supports abundant forests – including some of the world's largest trees in Sequoia sempervirens (Coastal redwood) groves–and, historically, one of California's major salmon and steelhead trout runs. The river basin was lightly populated by Native Americans before, and for decades after, the European settlement of California. The region remained little traveled until 1849, when Josiah Gregg and his exploring party arrived in search of land for settlement. The river
9504-526: The rest of the nation in that year. In 2005, the American Community Survey reported that 14.4% of Lake County's owner-occupied dwellings are valued over a half a million dollars. In the county, the population was spread out, with 24.1% under the age of 18, 6.0% from 18 to 24, 23.6% from 25 to 44, 26.8% from 45 to 64, and 19.5% who were 65 years of age or older. The median age was 43 years. For every 100 females there were 97.6 males. For every 100 females age 18 and over, there were 94.7 males. The median income for
9612-470: The river system. The non-native Sacramento pikeminnow is present; it competes with and preys on young salmonids. The Eel River has never contained true eels, but is named for the Pacific lamprey, an eel-shaped parasite that attaches itself to other fish during its ocean life-cycle. Like salmon and steelhead, lampreys are anadromous , meaning they live part of their life in the ocean but return to fresh water to spawn. They are Cyclostomes (Circle mouths),
9720-422: The river's salmon run. Due to huge earth-flows caused by the record rain in 1964, 105 million tons of sediment were carried down the Eel River between December 21–23 as measured at Scotia–more than in the previous eight years combined. This sediment scoured away or buried spawning grounds for salmon and steelhead trout, causing the populations of these fish to drop to dangerous levels by the mid-1970s. The flooding
9828-449: The scenic area. There are two hydroelectric dams on the Eel: 130-foot (40 m) Scott Dam, which forms Lake Pillsbury, and 50-foot (15 m) Cape Horn Dam , which forms Van Arsdale Reservoir just north of Potter Valley . At Cape Horn Dam, the majority of the water is diverted through a tunnel and hydroelectric plant, and then to the headwaters of the Russian River in Potter Valley and
9936-462: The settlers also faced conflict as they pushed deeper into Native American lands. American negotiator Colonel Reddick McKee 's treaty would have given the Indians a large reservation around the mouth of the Eel, but the treaties were never ratified. American settlements were made along the flat terraces of the Eel, near the confluence with the Van Duzen River and toward the mouth of the river where there
10044-407: The sometimes-mighty river to slow to a trickle. At its mouth, the Eel River produces an estimated annual runoff of 6.9 million acre-feet (8.5 km ) per year, or about 9,500 cu ft/s (270 m /s). The Eel's maximum recorded flow of 936,000 cu ft/s (26,500 m /s) on December 23, 1964, was the largest peak discharge of any California river in recorded history, and one of
10152-456: The south end of the lake as well as many old volcanoes , the largest being Cobb Mountain . The geologic history of the county shows events of great violence, such as the eruption of Mount Konocti and Mount St. Helena and the collapse of Cow Mountain , which created the hills around the county seat of Lakeport . Blue Lakes , Lake Pillsbury, and Indian Valley Reservoir are the county's other major bodies of water. Lake County has habitats for
10260-627: The southern flank of 6,740-foot (2,050 m) Bald Mountain, in the Upper Lake Ranger District of the Mendocino National Forest in Mendocino County. The river flows south through a narrow canyon in Lake County before entering Lake Pillsbury , the reservoir created by Scott Dam. Below the dam the river flows west, re-entering Mendocino County. At the small Cape Horn Dam about 15 miles (24 km) east of Willits , water
10368-464: The upper Eel River, causing the summer and winter runs to interbreed. Thus, there is an unusually high genetic similarity between summer-run and winter-run steelhead in the Eel River system, in contrast to other rivers in the Western United States . Human impacts have led to a dramatic decline of salmon and steelhead populations in the Eel River system. Large-scale commercial fishing began in
10476-582: The vote. On November 4, 2008, Lake County voted 52.6% for Proposition 8, which amended the California Constitution to ban same-sex marriages. In 2022, the county was won by Republicans in several statewide races. Lake County is in California's 4th congressional district , represented by Mike Thompson ( D – St. Helena ). In the state legislature , Lake is in the 4th Assembly District , represented by Democrat Cecilia Aguiar-Curry , and
10584-403: The watershed is located within Mendocino and Humboldt Counties. The Eel's major tributaries–the North Fork, Middle Fork, South Fork and Van Duzen Rivers, drain 286 square miles (740 km ), 753 square miles (1,950 km ), 689 square miles (1,780 km ), and 420 square miles (1,100 km ), respectively. The Middle Fork drains the greatest area of all the tributaries, but the South Fork
10692-417: The world's greatest wines. However, in 1920, national prohibition essentially ended Lake County's wine production. With authorized cultivation limited to sacramental purposes, most of the vineyards were ripped out and replanted with walnut and pear orchards. According to the U.S. Census Bureau , the county has a total area of 1,329 square miles (3,440 km ), of which 1,256 square miles (3,250 km )
10800-581: Was 68,163. The county seat is Lakeport . The county takes its name from Clear Lake , the dominant geographic feature in the county and the largest non-extinct natural lake wholly within California. ( Lake Tahoe is partially in Nevada ; the Salton Sea was formed by flooding; Tulare Lake was drained by the agricultural industry.) Lake County forms the Clearlake, California micropolitan statistical area . It
10908-462: Was also abandoned. ★ As of 2022, the U.S. Census continues to use the community's former name of Clear Lake Riviera . The population ranking of the following table is based on the 2010 census of Lake County. † county seat 39°05′N 122°46′W / 39.09°N 122.76°W / 39.09; -122.76 Eel River (California) The Eel River ( Wiyot : Wiya't ; Cahto : Taanchow ; Northern Pomo : ch'idiyu )
11016-489: Was also deleterious to rail service through the Eel River canyon. After the 1964 flood, much of the topography in the Eel River drainage has been permanently transfigured, and landslides occur more often, frequently damaging local road and rail infrastructure. In 1998, after another large flood in the winter of 1996–1997 washed out sections of the line, the Northwestern Pacific became the first railroad to be shut down by
11124-405: Was directly in the storm's path. With no major dams to control its flow, the main Eel reached a peak of 936,000 cu ft/s (26,500 m /s), with 200,000 cu ft/s (5,700 m /s) from the South Fork alone. Ten towns were obliterated with dozens of others damaged; at least 20 bridges were destroyed, and some were never rebuilt. The heavy damage was due not only to the water, but to
11232-427: Was more arable land than the steep upper canyons. Most of these areas were appropriated for agriculture and grazing land. Salmon canneries flourished on the lower Eel between the 1870s and the 1920s, and declined thereafter because of decreasing runs caused by overfishing and other manmade environmental changes. Logging companies also took hundreds of millions of board feet of timber from the basin, which were floated down
11340-485: Was named after they traded a frying pan to a group of Wiyot fishermen in exchange for a large number of Pacific lampreys , which the explorers mistook for eels. Explorers' reports of the fertile and heavily timbered region attracted settlers to Humboldt Bay and the Eel River Valley beginning in 1850. Starting in the late 19th century the Eel River supported a large salmon-canning industry which began to decline by
11448-552: Was named in 1849 at the dawn of the California Gold Rush by an exploring party led by Josiah Gregg . Except for Gregg, who was a physician, naturalist and explorer, the remainder of the party were miners from a temporary camp on the Trinity River at Helena . The party took months to travel overland by an extremely arduous route from Helena to the Pacific Ocean between November and December 1849, when they are credited with
11556-453: Was recorded between 1910 and 2012. This station measures runoff from an area of 3,113 square miles (8,060 km ), or 85 percent of the basin; however it does not include the flow of the Van Duzen River, which joins several miles downstream. Monthly average flows at Scotia range from 19,700 cu ft/s (560 m /s) in January to 138 cu ft/s (3.9 m /s) in September –
11664-547: Was won by just four Democratic nominees – Franklin D. Roosevelt in 1932 and 1936, Lyndon B. Johnson in 1964 and Jimmy Carter in 1976. Ronald Reagan in 1984 remains the last Republican to win a majority in the county, which has reverted to leaning Democratic. In 2016, Republicans broke 40% of the vote for the first time since 2004, and Democrats failed to win 50% of the vote for the first time since 1996. Democrats broke 50% again in 2020, increasing their margin of victory, although Republicans still increased their percentage of
