Congressional Districts: 14, 16, 17, 19, 25 



Congress authorized the Caloosahatchee River (C-43) West Basin Storage Reservoir Project in the Water Resources Reform Development Act (WRRDA) of 2014. This project is a component of the Comprehensive Everglades Restoration Plan (CERP). The project is designed to capture excess C-43 Basin runoff and regulatory releases from Lake Okeechobee during the wet season and release water from the reservoir during the dry season. The project includes development of one aboveground reservoir with a total storage capacity of approximately 170,000 acre-feet (ac-ft). The reservoir will be located in the C-43 Basin in Hendry County. The project will reduce the extreme salinity changes in the Caloosahatchee River Estuary by providing a more consistent flow of water discharging into the estuary. The project will also provide water supply benefits and some flood attenuation.


Estimated Total Cost $809,700,000

Allocation thru FY17 $154,448,000
Allocation for FY18 $1,500,000

The Final PIR and Integrated Environmental Impact Statement (EIS) were completed September 2007. The Chief’s Report was signed in March 2010 (the long delay was due to land valuation and crediting policy issues which needed to be resolved for this and other CERP projects). ASA(CW) and OMB reviews were completed and the Record of Decision (ROD) was signed in April 2010.

The C-43 West Basin Storage Reservoir project is one of the South Florida Water Management District’s (SFWMD) State-Expedited Projects. SFWMD is constructing this project in close coordination with the Corps. SFWMD completed final Plans and Specifications (P&S) in early 2008, and updated the P&S in FY15/FY16. They awarded the first construction contract in August 2015, and the second contract in April 2016. Contract 3 was awarded in December 2017, and Contract 4 is scheduled to be awarded in January 2019. Completion of construction is scheduled for December 2022.
