Caloosahatchee River (C-43) West Basin Storage Reservoir

The South Florida Water Management District is a regional governmental agency that manages the water resources in the southern part of the state. It is the oldest and largest of the state's five water management districts.

Our Mission is to manage and protect water resources

The Comprehensive Everglades Restoration Plan, the Congressionally approved framework for restoring, protecting and preserving the water resources of central and southern Florida, calls for construction of the 170,000 acre-foot Caloosahatchee River (C-43) West Basin Storage Reservoir Project. It will help store and manage basin runoff for meeting estuary needs during the dry season.

FEBRUARY 2017

Releases of water from the reservoir during the dry season will provide essential flows, resulting in improved salinity balance, survival of young fish and shellfish and improved ecological health. The reservoir is part of an overall solution to restore the river that includes water quality improvements, storage and operational changes.

Purpose and Benefits

? Capture and store stormwater runoff from the C-43 basin, reducing excess water flow to the Caloosahatchee Estuary.

? Capture and store federal regulatory releases from Lake Okeechobee, reducing discharges to the coastal estuaries.

? Improve the salinity balance for the Caloosahatchee Estuary by controlling peak flows during the wet season and providing essential flows during the dry season.

Project Status

The design of the project, which was initially completed in 2008, is now being updated to meet the current dam safety standards.

Demolition work on the site and preloading of earthen mounds that will be used to build the reservoir is well underway and expected to be completed in August 2017. The construction of the S-476 Pump Station associated with the reservoir is expected to be completed in April 2018. The entire reservoir project is expected to be completed by 2022 at a cost of approximately $500 miliion.
