Florida Bay is the bay located between the southern end of the Florida mainland (the Florida Everglades ) and the Florida Keys in the United States . It is a large, shallow estuary that while connected to the Gulf of Mexico, has limited exchange of water due to shallow mudbanks dividing the bay into many basins or lakes. The banks separate the bay into basins, each with its own unique physical characteristics.

The CDP also includes the neighboring island of Conch Key . The key was the site of a salt manufacturing operation in the 1820s & 1830s. Occupation of the island ceased after the Labor Day Hurricane of 1935 and did not resume until

The per capita income for the county was $ 26,102. About 6.80% of families and 10.20% of the population were below the poverty line , including 11.80% of those under age 18 and 8.80% of those age 65 or over. As of 2010, 77.57% spoke English as

The mud layer is thicker on islands covered by mangrovess , and in banks connecting the islands. Peat and caliche remnants from the Everglades tree islands remain under the islands and banks. As the rising sea level flooded the area that is now Florida Bay between 3,000 and 5,000 years ago, peat deposits from tree islands, shore levees , and irregularities in

Until about 1884, salinity at the location was greater than 25 ppt. From 1884 to about 1900 salinity was below 25 ppt, and below 18 ppt at times. From about 1900 to about 1910 salinity rose above 25 ppt. From 1910 to 1940, salinity

As the second most commonly caught species of fish in the Florida Bay, spotted seatrout comprise a large portion of the fishing industry and are integral to the ecosystem as well as surrounding economy. Water temperature of less than 80 °F (27 °C) and salinity levels below 37.5 parts per thousand (ppt) are ideal for seatrout spawning; however, water management stations in

Then, following the 2015 drought, extreme temperatures and heightened salinity reduced the amount of oxygen that could remain dissolved in the water, causing periods of anoxia during nighttime and thereby damaging the health of the turtlegrass in the bay. During the summer and fall of 2015, approximately 40,000 acres of seagrass died. Cyanobacterial harmful algae blooms (also known as blue-green algae) have flourished in
726-488: A series of ecological changes beginning in the late 1980s that have severely altered the ecosystem. Originally, clean freshwater flowed south through the state into the Florida Bay. To support the state's agricultural water needs, namely for sugar cultivation, the water was rerouted and no longer flows into the Bay. The flow of fresh water is believed to have caused environmental issues and loss of native wildlife. The rerouting of

The presence of remnants of the algae Halimeda in the packstone may indicate that it formed when the bay was more open. Mud mounds appear to be migrating over the basal packstone in the basins. The basal packstone in the basins has also been reworked by hurricanes. The bay's many basins that are broken up by banks serve as plentiful fishing grounds for snook ( Centropomus undecimalis ), redfish ( Sciaenops ocellatus ), spotted seatrout ( Cynoscion nebulosus) , tarpon ( Megaflops atlanticus), bonefish ( Albula vulpes) , and permit ( Trichinous falcatus) , among others.

Due to the influence of this community, Monroe County was the only county in Florida to reject 2008 Florida Amendment 2 , which banned same-sex marriage and civil unions in the state. The amendment passed in the state with 60% of the vote. Monroe County is politically divided by geography, with Key West voting reliably Democratic, Stock Island being politically variable, and

Most notably, Roseate spoonbills ( Platalea ajaja ), Reddish egrets ( Egretta rufescens ), and Great White Herons (A rdea herodias occidentalis ) have unique subpopulations that are largely restricted to Florida Bay.

Like much of the Solid South, in the first two-thirds of the 20th century, Monroe was a solidly Democratic county, supporting landslide losers like James M. Cox and John W. Davis . However, unlike most Southern Democrats, Monroe County voters tended to be far more liberal on social issues such as civil rights and later gay rights, voting powerfully for Lyndon B. Johnson in 1964 and even supporting Hubert Humphrey in 1968, one of only three counties to do so. Despite this, Richard Nixon did easily carry

The bay is open to the Gulf of Mexico to the west, but connection to the Atlantic Ocean to the east is restricted to narrow channels between the Florida Keys. The average tidal range along the western edge of the bay is 1 to 1.5 meters, but the tidal range diminishes quickly eastward in the bay due to the restricted flow of water between basins. Fresh water flow into

Tidal ranges are less than 15 centimetres (5.9 in) behind the first line of mud banks and absent in

Mounds in the inner part of the bay are smaller, and grow slowly because of low production rates of carbonate. The growth and development of mud banks is controlled by biological processes, including
2640-499: The bay is restricted to Taylor Slough and Trout Creek in the northeast corner of the bay, and is only 10% of the freshwater supply to the bay (rainfall provides the rest of the fresh water). Due to the poor circulation of water within the bay, salinity increases rapidly away from the margins of the bay, except for the northeast part of the bay where it receives fresh water from rivers. Water temperature ranges from 15 to 40 °C (59 to 104 °F) in interior bays. Cold fronts cross
2706-416: The bedrock surface served as nuclei for mud banks. The mud mounds (islands and banks) of Florida Bay, which divide the bay into many basins or lakes, are subject to various processes that degrade, move, and built the mounds.

By the mid 1930s, the three main species of wading birds in the bay (Roseate spoonbills, Reddish egrets, Great herons) were driven to near extinction by human harvesting for food and feathers. The cyanobacteria create an oxygen-free environment teaming with toxic gases, creating an unsuitable living environment for many marine and terrestrial animal species. As

There are tree islands throughout the Everglades, clusters of trees growing on slight elevations. Tree islands accumulate plant litter which becomes peat , which in turn facilitates the creation of caliche , a dense limestone crust on the limestone bedrock. As the bay flooded,

The first major die-off occurred from 1987 to 1991 as thousands of hectares of turtlegrass beds ( Thalassia testudinum ) were devastated by high levels of toxic dissolved sulfide. 10,000 acres died in the central and western bay, and almost 60,000 additional acres suffered reduced productivity and biomass as

Those conditions continued until about 1910, when the pre-1840 conditions returned, with relatively dense vegetation on the bay floor. The bay floor remains covered with vegetation, but variations in the foraminifera and mollusc species present indicate rapid oscillations in salinity levels since 1940. Around 1970, changes in species and
