Caloosahatchee River and Estuary
The Caloosahatchee River and Estuary are west coast treasures, enjoyed by residents and visitors alike. Recognizing that the health of the river and its estuary is essential to the overall way of life for area residents, the South Florida Water Management District considers protection and improvement of the Caloosahatchee watershed an agency priority.
Extensive historical modifications to the Caloosahatchee River and its watershed have altered the hydrology of the region. As a result, heavy rainfall can bring large influxes of fresh water into the Caloosahatchee Estuary from stormwater runoff within the basin, Lake Okeechobee releases or both. The increased freshwater flows affect salinity levels and water quality in the estuary, potentially causing environmental harm.
To address these issues, the South Florida Water Management District is working with the U.S. Army Corps of Engineers and other federal, state and local partners on a variety of strategies to improve the health of the Caloosahatchee Estuary.

Background / Local Watershed
Beginning in the late 19th century, the Caloosahatchee River and its watershed underwent extensive modifications that drastically altered the hydrology of the region. The once shallow and crooked river was deepened and widened into a regulated waterway that was connected to Lake Okeechobee and the Kissimmee Chain of Lakes for navigation, water supply and flood control purposes.
