The Kissimmee River is a river in south-central Florida, United States that forms the north part of the Everglades wetlands area. The river begins at East Lake Tohopekaliga south of Orlando, flowing south through Lake Kissimmee into the large, shallow Lake Okeechobee. Hurricane-related floods in 1947 prompted channelization of the meandering lower stretch, completed by 1970. The straightened course reduced wetland habitat and worsened pollution. In response, efforts since the 1990s have partially restored the river's original state and revitalized the ecosystem, as part of the broader restoration of the Everglades.
The Kissimmee River arises in Osceola County as the outflow from East Lake Tohopekaliga, passing through Lake Tohopekaliga, Lake Cypress, Lake Hatchineha and Lake Kissimmee. Below Lake Kissimmee, the river forms the boundary between Osceola County and Polk County, between Highlands County and Okeechobee County, and between Glades County and Okeechobee County before it flows into Lake Okeechobee. The river was originally 134 miles (216 km) in length, 103 miles (166 km) of which was between Lake Kissimmee and Lake Okeechobee. It forms the headwaters of the Kissimmee River-Lake Okeechobee-Everglades ecosystem.
The Kissimmee River watershed of 3,000 square miles (7,800 km2) is adjacent to the Eastern Continental Divide, with triple watershed points at the Miami (north), Withlacoochee (northwest), and Peace (west) rivers' watersheds and the Lake Okeechobee watershed (southwest).[ specify ] The floodplain of the river supports a diverse community of waterfowl, wading birds, fish, and other wildlife.
The 1947 Atlantic hurricane season, which included the 1947 Fort Lauderdale Hurricane and the 1947 October Hurricane, produced very heavy rainfall and flooding over most of central and southern Florida. Florida requested federal assistance in controlling future floods, and in 1954 the United States Congress authorized the canalization of the Kissimmee River. From 1962 to 1970 the United States Army Corps of Engineers dredged the C-38 Canal down the Kissimmee valley, shortening the 103-mile (166 km) distance from Lake Kissimmee to Lake Okeechobee to just 56 miles (90 km). It has since been realized that this project damaged the river, with the faster water flow leading to major environmental problems in the Kissimmee Valley and Lake Okeechobee. Efforts are currently underway to reverse the process and re-introduce the many oxbows in the river that slowed the water. [2]
After the river channel was straightened, 40,000 acres (160 km2) of floodplain below Lake Kissimmee dried out, reducing the quality of waterfowl habitat by ninety percent, and the number of herons, egrets and wood storks by two-thirds. Catches of largemouth bass in the river were consistently worse after the channelization. While the Kissimmee was not a significant source of pollution for Lake Okeechobee before channelization, in the 1970s and later the river contributed about 25% of the nitrogen and 20% of the phosphorus flowing into the lake. [2]
In protest to the canalization of the river and its resultant damage to the habitat, Florida author Piers Anthony based the plot of the tenth Xanth novel, Vale of the Vole , around the straightening of the "Kiss-Mee River," an obvious parody to "Kissimmee."
The river was mentioned in a lyric of Josh Turner's song "Alligator Stroll".
Efforts to restore the Kissimmee River to its original flow were approved by Congress in 1992, and began with modification to the headwater lakes in 1997. [3] The project was initially estimated to be completed by 2011, [4] but in 2010 the United States Army Corps of Engineers stated it hoped to complete the project in 2015. [5] Restoration was eventually completed in July 2021. [6] In all, about 44 miles (71 km) of the Kissimmee River was restored, plus 20,000 acres of wetlands. [7]
In 2006, the South Florida Water Management District had acquired enough land along the river and in the upper chain of lakes to complete restoration.
A 2009 report from the Corps of Engineers went into detail with the issues and plans for the Kissimmee River restoration. [8]
The restoration project was completed on July 29, 2021. It restored 40 miles (64.3 km) of river and almost 25,000 acres of wetlands. [9] Lake Kissimmee is expected to rise one and a half feet, restoring water sequestration functions and easing seasonal droughts. [9]
Already, wildlife is returning to the restored sections of river. When flooding began again, muck and smothering aquatic weeds were flushed out. Sandbars reemerged. Encroaching dry land trees began dying back. Once-dormant plants began to reestablish themselves. The species included pink-tipped smartweed, horsetail, sedges, rushes, arrowhead, duck potato and pickerel weed. Flooding and continuous flow increased levels of dissolved oxygen in the water, creating near perfect conditions for aquatic invertebrates such as insects, mollusks, works, crayfish and freshwater shrimp. This, in turn, boosted fish populations and it led to a rise in bird and alligator populations. The entire food chain benefitted. This is one reason that the Kissimmee River restoration is considered to be the largest true ecosystem restoration project in the world, attracting ecologists from other states and countries. [10]
The Everglades is a natural region of tropical wetlands in the southern portion of the U.S. state of Florida, comprising the southern half of a large drainage basin within the Neotropical realm. The system begins near Orlando with the Kissimmee River, which discharges into the vast but shallow Lake Okeechobee. Water leaving the lake in the wet season forms a slow-moving river 60 miles (97 km) wide and over 100 miles (160 km) long, flowing southward across a limestone shelf to Florida Bay at the southern end of the state. The Everglades experiences a wide range of weather patterns, from frequent flooding in the wet season to drought in the dry season. Throughout the 20th century, the Everglades suffered significant loss of habitat and environmental degradation.
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, and 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.
Lake Okeechobee, also known as Florida's Inland Sea, is the largest freshwater lake in the U.S. state of Florida. It is the tenth largest natural freshwater lake among the 50 states of the United States and the second-largest natural freshwater lake contained entirely within the contiguous 48 states, after Lake Michigan.
The Caloosahatchee River is a river on the southwest Gulf Coast of Florida in the United States, approximately 67 miles (108 km) long. It drains rural areas on the northern edge of the Everglades, east of Fort Myers. An important link in the Okeechobee Waterway, a manmade inland waterway system of southern Florida, the river forms a tidal estuary along most of its course and has become the subject of efforts to restore and preserve the Everglades.
The Okeechobee Waterway or Okeechobee Canal is a relatively shallow artificial waterway in the United States, stretching across Florida from Fort Myers on the west coast to Stuart on Florida's east coast. The waterway can support tows such as barges or private vessels up to 50 feet wide x 250 feet long which draw less than 10 feet, as parts of the system, especially the locks may have low water depths of just ten feet. The system of channels runs through Lake Okeechobee and consists of the Caloosahatchee River to the west of the lake and the St. Lucie Canal east of the lake.
The Herbert Hoover Dike is a dike around the waters of Lake Okeechobee in Florida.
The Belle Glade culture, or Okeechobee culture, is an archaeological culture that existed from as early as 1000 BCE until about 1700 CE in the area surrounding Lake Okeechobee and in the Kissimmee River valley in the Florida Peninsula.
The St. Lucie River is a 35-mile-long (56 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.
The Comprehensive Everglades Restoration Plan (CERP) is the plan enacted by the U.S. Congress for the restoration of the Everglades ecosystem in southern Florida.
The environment of Florida in the United States yields an array of land and marine life in a mild subtropical climate. This environment has drawn millions of people to settle in the once rural state over the last hundred years. Florida's population increases by about 1,000 residents each day. Land development and water use have transformed the state, primarily through drainage and infill of the wetlands that once covered most of the peninsula.
The South Florida Water Management District (SFWMD) is a regional governmental district 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.
Before drainage, the Everglades, a region of tropical wetlands in southern Florida, were an interwoven mesh of marshes and prairies covering 4,000 square miles (10,000 km2). The Everglades is both 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.
A national push for expansion and progress toward the latter part of the 19th century stimulated interest in draining the Everglades, a region of tropical wetlands in southern Florida, for agricultural use. According to historians, "From the middle of the nineteenth century to the middle of the twentieth century, the United States went through a period in which wetland removal was not questioned. Indeed, it was considered the proper thing to do."
An ongoing effort to remedy damage inflicted during the 20th century on the Everglades, a region of tropical wetlands in southern Florida, 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.
The Water Resources Development Act of 2000, Pub. L. 106–541 (text)(PDF), was enacted by Congress of the United States on December 11, 2000. Most of the provisions of WRDA 2000 are administered by the United States Army Corps of Engineers.
Fisheating Creek is a stream that flows into Lake Okeechobee in Florida. It is the only remaining free-flowing water course feeding into the lake, and the second-largest natural source for the lake. Most of the land surrounding the stream is either publicly owned or under conservation easements restricting development. The lower part of the stream remains in a largely natural state, and efforts are underway to restore the upper part of the stream to a more natural state.
The Everglades Headwaters National Wildlife Refuge and Conservation Area, created in 2012, the newest addition and 556th unit of the United States National Wildlife Refuge (NWR) System, began with 10 acres (4.0 ha) donated to the conservation effort as part of the Obama administration's America's Great Outdoors Initiative.
Middle Creek is a creek that drains through Rodman Slough into Clear Lake in Lake County, California. It supplies 21% of the streamflow to Clear Lake. The watershed vegetation has been drastically modified by European settlers through sheep and cattle grazing, logging and farming in the valley floors. The creek once flowed through extensive wetlands at its mouth, but these were mainly drained to create farmland, apart from Rodman Slough on the west side. There are now projects to restore the drained land to its original condition.
