Fresh water from the Peace River watershed is essential to the health of the Charlotte Harbor, the second largest estuary in Florida. The watersheds of the Myakka and Caloosahatchee rivers also feed into the harbor.
An estuary is a partially enclosed body of water where fresh water from rivers and streams flows into the ocean. The Charlotte Harbor estuary is 30 miles long by seven miles wide and boasts 219 miles of shoreline.…
May 2026Q: What is a water control structure?A: The primary purpose of the District’s water control structures is to manage the flow of water in lakes and river systems. Water control structures vary greatly in size and complexity. The District’s water control structures can be broadly classified into three categories: flood control, water conservation, and salinity barriers. Collectively, these structures allow the…
The Chassahowitzka Springs form the headwaters of the Chassahowitzka River in the town of Homosassa. It is considered one of the more scenic rivers in Florida as it flows nearly seven miles through mostly undeveloped area before discharging into the Gulf of America near the Citrus and Hernando County border. Most of the lands adjacent to the river are in public ownership, meaning they will retain much of their natural beauty for generations to come.…
Unlike the clear, cool waters of the Springs Coast Watershed's spring-fed rivers, the Pithlachascotee is a blackwater stream that is more than 20 miles long and originates in the Crews Lake area of Pasco County. Along with the Anclote River, the locally nicknamed "Cotee" River crosses the District's Starkey Wilderness Park and meanders through Pasco County. It…
Weeki Wachee Springs has an extensive underwater cave system and is known for its world-famous mermaids. About the SpringsThe Weeki Wachee River is a first-magnitude spring system originating in Hernando County. The headspring is home to …
The Peace River watershed is home to an extraordinary assortment of plants and animals. Some are common; some are extremely rare.Coreopsis, the state wildflower, is widespread. Its delicate yellow blooms brighten the riverbanks year-round. The riverbanks are also lined with palmettos, cypress, water locust, sweet gum, cabbage palm and live oak. Some of the trees have dark, muddy skirts. These are the high-water marks of the seasonal floods. Nearing the estuary, red,…
July 2024Q: What is an aquifer?A: An aquifer is a body of underground rock and/or sediment that stores water. The groundwater within an aquifer can fill the spaces between grains of sand and gravel, or it can fill the cracks and fissures in solid rock.Q: Are there different types of aquifers?A: In west-central Florida the groundwater system is comprised of three main aquifer units; the surficial aquifer, the…
Made up of a dozen springs, Chassahowitzka Springs is the headwaters of one of the most ecologically healthy rivers in west-central Florida. About the SpringsThe Chassahowitzka River is a first-magnitude spring system that originates in southwest Citrus County. The river is known for being short and shallow, flowing 5.6 miles from the…
Our journey along the Withlacoochee River begins in the cypress domes and forested wetlands of the Green Swamp. Four rivers emerge from this large oasis between Tampa and Orlando. It is an area of ecological and hydrologic importance because of its ability to store surface water and slow floodwaters while sustaining flow to multiple rivers and streams. The Green Swamp also supplies water to the aquifer, which isn’t too far below the land’s surface in…
The history of the Withlacoochee River watershed is important because it is still being impacted by how people used the land as far back as the 1800s.Awareness of the river grew around the 1830s and 40s, during the 2nd Seminole War. During the war, shallow-draft steamers were used to transport materials and men on the river. Then, the late 1800s brought several booming industries to the area, including phosphate, timber and produce…

Join us in the community effort to protect the Chassahowitzka River. The Chassahowitzka River is a great place to experience natural Florida. The river flows 5.6 miles from the headsprings to where it meets the Gulf of America at Chassahowitzka Bay in Citrus County. It’s a popular spot for kayaking and boating. But increased recreational activities have had negative…
The 7.5 mile-long Weeki Wachee River is another spring-fed river on the Springs Coast. Its headwater is Weeki Wachee Springs, one of Florida’s legendary roadside attractions where tourists, including Elvis Presley, have been coming to see the famous live mermaids in the underwater theater since the 1940s. The headsprings and surrounding land are now owned by the Southwest Florida Water Management District and managed by the Florida Park Service as Weeki Wachee Springs State…
Southwest Florida Water Management District (District) is one of five regional agencies directed by state law to protect and preserve water resources within its boundaries. Established in 1961 to operate and maintain several large flood protection projects, the District’s responsibilities have expanded to include managing water supply and protecting water quality and the natural systems — rivers, lakes, wetlands and associated uplands.Origin and EvolutionThe Southwest…
The beat of central Florida’s hydrologic heart lies between Tampa and Orlando in 560,000 acres of Florida backcountry called the Green Swamp. The Green Swamp includes portions of Polk, Lake, Sumter, Hernando and Pasco counties. Within these acres is a complex, integrated and delicate natural system composed of cypress swamps, hardwood forests, marshes, pine flatwoods and sandhills. Emerging from this precious oasis are the Hillsborough, Withlacoochee, Ocklawaha and…
The Southwest Florida Water Management District is currently developing new minimum flow standards for the Upper Peace River. Minimum flows are intended to prevent significant harm to the water resources or ecology of an area that may be caused by water withdrawals. The draft minimum flows report for the Upper Peace River,…
