The Caloosahatchee River Connection

Sanibel's bay waters, where freshwater of the Caloosahatchee River meets the Gulf of Mexico are some of the richest fishing grounds in the world. But our local waters need our help. Caloosahatchee restoration is not possible without Everglades restoration.

As part of the efforts to drain Florida's great interior "swamp" and create dry lands for homes and agriculture, the Caloosahatchee River was connected to Lake Okeechobee.
Since then, the river has been used to quickly divert water out to sea that historically flowed south to the Everglades

Modern engineered Everglades
Today, a web of canals and water control structures determines the timing and quality of water flows.

SCCF and the City of Sanibel are working with many other local, regional and state groups to "get the water right" and protect our sanctuary.

· Freshwater Meets Saltwater
The aquatic plants and animals living in the bay depend on certain rages in the salinity (or saltiness) of the water. The amount of Caloosahatchee freshwater coming into the bay
influences that salinity.

· South Florida Averages 55" of Rain per Year, Almost All in the Summer
Because the water levels in Lake Okeechobee determines releases to the Caloosahatchee, salinity is the summer is often too low; in the winter too high.

Consequences of a broken system

· In 2004-2006, billions of gallons of polluted water were released down the Caloosahatchee and St. Lucie Rivers because rains from hurricanes raised water levels in Lake Okeechobb too high. In on six-week period in 2004, lake levels rose six feet.

· 2005's Hurricane Katrina raise safety concerns about the Herbert Hoover Dike, which rings Lake Okeechobee, forcing water managers to lower lake levels The Dike is currently under repair .
· 2008, one tropical storm dumped 40" of rain in 17 days.

Oyster reefs and seagrass meadows provide feeding sites and vital nursery habitats for many estuarine, marine and freshwater species including fishes, shrimp, crabs, mammals, and birds. Both oysters and seagrasses are sensitive to changes in salinity and are often negatively impacted by declining water quality.
