The Ichetucknee River is a spring-fed, pristine river in North Central Florida. The entire 6 miles (9.7 km) of the river average 20 feet (6.1 m) wide, 5 feet (1.5 m) deep and most of the 6 miles lie within the boundaries of the Ichetucknee Springs State Park while the rest is to the south of US Highway 27. Three Rivers Estates Property Owners (TREPO) is the property owner association that manages the area along the private side of the river as it travels & flows into the Santa Fe.
The name is derived from a Native American language, possibly Creek wa (water), echas (beaver), and toka or tomeka (because of, or caused by), meaning "beaver pond" (beaver remains are common in the riverbed). A Hitchiti informant to anthropologist John R. Swanton pronounced the name "Oetcotukni", and translated it as "where there is a pond of water", likely referring to a defunct beaver pond.
The water in the river is crystal-clear and is 72 °F (22 °C) year-round. There are nine named springs within the Ichetucknee Springs group with an average total flow of 212 million gallons per day. The group includes: Ichetucknee Springs, Cedar Head Spring, Blue Hole Spring, Roaring Springs, Singing Springs, Boiling Spring, Grassy Hole Springs, Mill Pond Spring, and Coffee Spring. The Ichetucknee is a tributary of the Santa Fe River, which in turn flows into the Suwannee River before emptying into the Gulf of Mexico.
The park restricts launch and end points along the river, permitting a tube/raft excursion of 45 min, 1.5 or 3 hours. A variety of commercial vendors, located outside the entrance to the park, rent tubes and rafts for a modest fee.
Park wildlife includes: North American River Otter, North American Beaver, turtle, ibis, Wood Stork, egret, Great Blue Heron, cormorant, Anhinga, Belted Kingfisher, Limpkin, Wild Turkeys, Wood Ducks, White-tailed deer, Raccoon, Nine-banded Armadillos, Wild Boars, The fish are primarily bream, Bluegill, Largemouth bass, Alligator gar, mullet, and catfish. West Indian Manatees have been seen in the winter months.
The 17th-century Spanish Fig Springs mission site has been identified in the park. This is probably the site of Mission San Martín de Timucua, which served the Timucua chiefdom known as the Northern Utina. Plans to reconstruct the mission and open it to the public as an interpretational site were dropped. The area was abandoned in the mid 19th century due to war, but was later held by American settlers.
 Current threats
In the early 1990s, the springs were showing signs of an even more disturbing degradation: a progressive decline in water quality. The Florida Department of Environmental Protection commissioned studies which showed that nutrient levels were steadily increasing. Additionally, some swimmers and tubers began to report strange skin rashes, possibly caused by algae fed by nutrients introduced into the aquifer.
