Crystal River is a very short river in Citrus County, Florida, flowing into the Gulf of Mexico. It is just seven miles (eleven kilometers) long, and has a drainage basin of five square miles (thirteen square kilometers), joining Kings Bay to the Gulf of Mexico. The river's significance is in the thirty natural springs that add an average of 300 million gallons (1,135 million liters) of warm water to the river every day. These springs include Three Sisters Springs.
The warm water in the river attracts large numbers of manatees, and Kings Bay, at the head of the river and the location of 28 of the springs, harbors approximately 350 manatees during the winter. Some biologists consider Crystal River to be the most important refuge for manatees in the United States. [1]
In the first half of the 19th century Crystal River was known as Weewahiiaca (wee-wah-heye-ih-YAH-kah), believed to be from the Creek language words wewa, meaning "water", and haiyayaka, meaning "clear". The city of Crystal River is located on the river. The Crystal River Energy Complex, which consists of four coal-burning power plants and the Crystal River Nuclear Plant, is located near the mouth of the river. The Crystal River Archaeological State Park is located on the river.
Kings Bay is Crystal River's headwater, or point of origin, and is fed by a number of springs that produce a constant temperature of 72 °F all year round. The 72° water attracts hundreds upon hundreds of manatees during the winter months looking to escape the cold water of the Gulf of Mexico. The springs in Kings Bay provide a habitat for 15 to 20 percent of the overall US manatee population. [2]
Recent studies have shown the nitrate level of Crystal River and Kings Bay has been on the rise. Historical water quality data from the early 1900s show that nitrate concentrations were 20 times lower than they are now. The main source of the nitrogen and phosphorus is ground water discharge from area springs and the overuse of inorganic fertilizers.
Lyngbya, a cyanobacteria, has been a problem in Kings Bay and Crystal River. It can be toxic to manatees, can cause many health issues in humans, and harmful to Crystal Rivers tourism. So far over 1,000 tons of Lyngbya have been removed with mechanical harvesters and raking. Removing Lyngbya mats does not help the regrowth of native grasses, and if you replant the native grasses it will most likely not succeed due to grazing of manatees.
Introduced exotic aquatic plants have been an issue for Crystal River/Kings Bay since the 1960s. [3] Hydrilla and Eurasian watermilfoil have been the main concern. The plants make it difficult for boaters to navigate by getting stuck in the propeller.
A project has been underway in Kings Bay (Crystal River) since 2012 to use water hyacinth and water lettuce to improve the water quality and reduce algae growth. Even though water hyacinth is an exotic plant and has been a problem in the past, they have re-introduced them in PVC corrals where the hyacinth would filter out the toxins and kill off phytoplankton algae that are making the water green. The PVC corrals are necessary due to the fact that manatees love to graze on this aquatic plant. The Kings Bay Adaptive Management Group (KBAM) heads this project.
Manatees are large, fully aquatic, mostly herbivorous marine mammals sometimes known as sea cows. There are three accepted living species of Trichechidae, representing three of the four living species in the order Sirenia: the Amazonian manatee, the West Indian manatee, and the West African manatee. They measure up to 4.0 metres long, weigh as much as 590 kilograms (1,300 lb), and have paddle-like tails.

Tampa Bay is a large natural harbor and shallow estuary connected to the Gulf of Mexico on the west-central coast of Florida, comprising Hillsborough Bay, McKay Bay, Old Tampa Bay, Middle Tampa Bay, and Lower Tampa Bay. The largest freshwater inflow into the bay is the Hillsborough River, which flows into Hillsborough Bay in downtown Tampa. Many other smaller rivers and streams also flow into Tampa Bay, resulting in a large watershed area.
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 Nature Coast is an informal, unofficial region of the U.S. state of Florida. The broadest definition of the Nature Coast includes the eight counties that abut the Gulf of Mexico along the Big Bend Coast defined by geologists: from west to east, Wakulla, Jefferson, Taylor, Dixie, Levy, Citrus, Hernando, and Pasco counties. The name "Nature Coast" was originally devised as part of a marketing campaign to promote tourism in Levy, Citrus, Hernando, and parts of Marion and Pasco counties.
The West Indian manatee, also known as the North American manatee, is a large, aquatic mammal native to warm coastal areas of the Caribbean, from the eastern United States to northern Brazil. Living alone or in herds, it feeds on underwater plants and uses its whiskers to navigate. It is divided into two subspecies, the Florida manatee in the United States and the Antillean manatee in the Caribbean, both of which are endangered and face pressure from habitat loss, pollution, and other human activity. The West Indian manatee is the largest living member of the sirenians, a group of large aquatic mammals that includes the dugong, other manatees, and the extinct Steller's sea cow.

It is accessible by boat from a nearby public boat ramp that is located at the campground that also bears its Indian name which means "land of hanging pumpkins;" a reference to a wild variety that once grew along the banks.
The Nature Coast State Trail (NCST) is a 31.7-mile long segment of Florida's Statewide System of Greenways and Trails System built along abandoned railroad tracks, and designated by the U.S. Department of the Interior as a National Recreation Trail. It has two primary sections following unused rail lines that were originally built by the Atlantic Coast Line Railroad.
