Shark River Slough (SRS) is a low-lying area of land that channels water through the Florida Everglades, beginning in Water Conservation Area 3, flowing through Everglades National Park, and ultimately into Florida Bay. [1] Together with Taylor Slough to the east, Shark River Slough is an essential conduit of overland freshwater to Florida Bay. Shark River Slough is also known as the "River of Grass." [2]

Water Conservation Area 3

Water Conservation Area 3 (WCA-3) is the largest existing WCA covering a total of 915 square miles within Western Dade and Broward Counties. Lying Southwest of WCA-2 and just North of Everglades National Park, WCA-3 is used primarily as an area to receive flood waters from adjacent areas and store them for beneficial municipal, urban, and agricultural uses. It was subdivided into WCA-2A and WCA-2B by way of the L-67 canal and levees as a safeguard against seepage into the aquifer.

Everglades National Park United States National Park in the US state of Florida

Everglades National Park is an American national park that protects the southern twenty percent of the original Everglades in Florida. The park is the largest tropical wilderness in the United States, and the largest wilderness of any kind east of the Mississippi River. An average of one million people visit the park each year. Everglades is the third-largest national park in the contiguous United States after Death Valley and Yellowstone. UNESCO declared the Everglades & Dry Tortugas Biosphere Reserve in 1976, and listed the park as a World Heritage Site in 1979, while the Ramsar Convention included the park on its list of Wetlands of International Importance in 1987. Everglades is one of only three locations in the world to appear on all three lists.

Florida Bay The bay between the southern end of the Florida mainland and the Florida Keys in the United States

Florida Bay is the bay located between the southern end of the Florida mainland 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 various shallow mudbanks covered with seagrass. The banks separate the bay into basins, each with their own unique physical characteristics.

Description

Shark River Slough is the dominant path for flow of water into Everglades National Park. [3] SRS is a mixture of sawgrass marshes, tree islands, sloughs, and wet prairies. [4] The SRS is bordered by marl prairies.

Everglades restoration

Historically, Shark River Slough was the primary path for water flow in the Everglades system. [5] Restoration of the historic function of the slough is essential to restoration of Everglades National Park. [6]

Tidal influence

Shark River Slough has tides from the Gulf of Mexico that reach 30 km inland. [7]

Gulf of Mexico An ocean basin and marginal sea of the Atlantic Ocean, largely surrounded by the North American continent

The Gulf of Mexico is an ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida border the Gulf on the north, which are often referred to as the "Third Coast", in comparison with the U.S. Atlantic and Pacific coasts.

Swamp A forested wetland

A swamp is a wetland that is forested. Many swamps occur along large rivers where they are critically dependent upon natural water level fluctuations. Other swamps occur on the shores of large lakes. Some swamps have hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates periodic inundation or soil saturation. The two main types of swamp are "true" or swamp forests and "transitional" or shrub swamps. In the boreal regions of Canada, the word swamp is colloquially used for what is more correctly termed a bog, fen, or muskeg. The water of a swamp may be fresh water, brackish water or seawater. Some of the world's largest swamps are found along major rivers such as the Amazon, the Mississippi, and the Congo.

Lake Okeechobee freshwater lake in the state of Florida

Lake Okeechobee, also known as Florida's Inland Sea, is the largest freshwater lake in the state of Florida. It is the ninth largest natural freshwater lake in the United States and the second largest natural freshwater lake contained entirely within the contiguous United States. Okeechobee covers 730 square miles (1,900 km2), approximately half the size of the state of Rhode Island, and is exceptionally shallow for a lake of its size, with an average depth of only 9 feet. The Kissimmee River, located directly north of Lake Okeechobee, is the lake's primary source. The lake is divided between Glades, Okeechobee, Martin, Palm Beach, and Hendry counties. All five counties meet at one point near the center of the lake.

Picayune Strand State Forest

Picayune Strand State Forest is one of 37 state forests in Florida managed by the Florida Forest Service. The 78,000-acre forest consists primarily of cypress swamps, wet pine flatwoods and wet prairies. It also features a grid of closed roads over part of it, left over from its previous land development schemes.

Mississippi River Delta plain

The Mississippi River Delta region is a 3-million-acre (12,000 km2) area of land that stretches from Vermilion Bay on the west, to the Chandeleur Islands in the Gulf of Mexico on the southeastern coast of Louisiana. It is part of the Louisiana coastal plain, one of the largest areas of coastal wetlands in the United States. The Mississippi River Delta is the 7th largest river delta on Earth (USGS) and is an important coastal region for the United States, containing more than 2.7 million acres of coastal wetlands 4,000 square miles (10,000 km2) and 37% of the estuarine marsh in the conterminous U.S. The coastal area is the nation's largest drainage basin and drains about 41% of the contiguous United States into the Gulf of Mexico at an average rate of 470,000 cubic feet per second.

Big Cypress National Preserve swamp

Big Cypress National Preserve is a United States National Preserve located in South Florida, about 45 miles west of Miami on the Atlantic coastal plain. The 720,000-acre (2,900 km2) Big Cypress, along with Big Thicket National Preserve in Texas, became the first national preserves in the United States National Park System when they were established on October 11, 1974. In 2008, Florida film producer Elam Stoltzfus featured the preserve in a PBS documentary.

Hammock (ecology) ecosystem in Southeastern United States consisting of stands of trees, usually hardwood, that form an ecological island within a contrasting ecosystem

Hammock is a term used in the southeastern United States for stands of trees, usually hardwood, that form an ecological island in a contrasting ecosystem. Hammocks grow on elevated areas, often just a few inches high, surrounded by wetlands that are too wet to support them. The term hammock is also applied to stands of hardwood trees growing on slopes between wetlands and drier uplands supporting a mixed or coniferous forest. Types of hammocks found in the United States include tropical hardwood hammocks, temperate hardwood hammocks, and maritime or coastal hammocks. Hammocks are also often classified as hydric, mesic or xeric. The types are not exclusive, but often grade into each other.

Shark Valley

Shark Valley is a geological depression at the head of the Shark River Slough in far western Miami-Dade County, Florida, United States. It is currently part of Everglades National Park. Shark Valley empties into Shark River in the Ten Thousand Islands of Monroe County. Shark Valley characteristically includes sawgrass prairie that floods during the rainy season, hence the name "river of grass"—Pa-Hay-Okee, from the Mikasuki language—for such marshes in the Everglades. Shark Valley features a Visitor Center with educational displays, a park video, an underwater camera and informational brochures. The entrance to Shark Valley is located along Tamiami Trail near the Miami-Dade–Collier County line.

St. Lucie River river in the United States of America

The St. Lucie River is a 7-mile-long (11 km) estuary linked to a coastal river system in St. Lucie and Martin counties in the Florida, United States. The St. Lucie River and St. Lucie Estuary are an "ecological jewel" of the Treasure Coast, central to the health and well-being of the surrounding communities. The river is part of the larger Indian River Lagoon system, the most diverse estuarine environment in North America with more than 4,000 plant and animal species, including manatees, oysters, dolphins, sea turtles and seahorses.

Florida Department of Environmental Protection

The Florida Department of Environmental Protection (FDEP) is the Florida government agency charged with environmental protection. It is under the nominal control of the governor.

The South Florida Water Management District (SFWMD) is a regional governmental agency that oversees water resources from Orlando to the Florida Keys. The mission of the SFWMD is to manage and protect water resources by balancing and improving water quality, flood control, natural systems and water supply, covering 16 counties in Central and Southern Florida. It is the largest water management district in the state, managing water needs for 7.7 million residents. A key initiative is the restoration of America's Everglades – the largest environmental restoration project in the nation's history. The District is also working to improve the Kissimmee River and its floodplain, Lake Okeechobee and South Florida's coastal estuaries.

The Cape Sable seaside sparrow is a subspecies of the seaside sparrow, a species of bird in the family Passerellidae native to the United States. This subspecies is endemic to southern Florida. It is designated endangered under the Endangered Species Act.

Geography and ecology of the Everglades

The geography and ecology of the Everglades involve the complex elements affecting the natural environment throughout the southern region of the U.S. state of Florida. Before drainage, the Everglades were an interwoven mesh of marshes and prairies covering 4,000 square miles (10,000 km2). The Everglades is simultaneously a vast watershed that has historically extended from Lake Okeechobee 100 miles (160 km) south to Florida Bay, and many interconnected ecosystems within a geographic boundary. It is such a unique meeting of water, land, and climate that the use of either singular or plural to refer to the Everglades is appropriate. When Marjory Stoneman Douglas wrote her definitive description of the region in 1947, she used the metaphor "River of Grass" to explain the blending of water and plant life.

Restoration of the Everglades

The restoration of the Everglades is an ongoing effort to remedy damage inflicted on the environment of southern Florida during the 20th century. It is the most expensive and comprehensive environmental repair attempt in history. The degradation of the Everglades became an issue in the United States in the early 1970s after a proposal to construct an airport in the Big Cypress Swamp. Studies indicated the airport would have destroyed the ecosystem in South Florida and Everglades National Park. After decades of destructive practices, both state and federal agencies are looking for ways to balance the needs of the natural environment in South Florida with urban and agricultural centers that have recently and rapidly grown in and near the Everglades.

Slough (hydrology) term in hydrology

A slough is a wetland, usually a swamp or shallow lake, often a backwater to a larger body of water. Water tends to be stagnant or may flow slowly on a seasonal basis.

Marl prairie

Marl prairies are wet prairies that allow for a slow seepage of overland water and exist in the Everglades, usually bordering deeper sloughs, and contain low-growth vegetation.
