C-111 Spreader Canal

This project will be implemented via two Project Implementation Reports (Western PIR and Eastern PIR). Project objectives include:

  • Restore the quantity, timing and distribution of water delivered to Florida Bay via Taylor Slough to levels nearest as possible to the pre-drainage model runs.

  • Improve hydroperiods and hydropatterns in the Southern Glades and Model Lands. Hydroperiods will be improved to support historical vegetation patterns nearest as possible to the pre-drainage model runs; and hydropatterns will be restored to historical sloughs with associated tributaries.

  • Return coastal zone salinity levels in western Florida Bay to levels as close as possible to pre-drainage scenario model runs by restoring upstream water levels in eastern Everglades National Park.

The Western PIR recommended plan includes a 590-acre Frog Pond detention area and a 225 cfs pump station; creating a mound of groundwater to the south and west, by preventing groundwater seepage to the east and improving water deliveries (quantity, timing and distribution) to Eastern Florida Bay. It also includes a second 225 cfs pump station and modifications to increase the water level in the Aerojet Canal to further prevent groundwater seepage to the east.

The Eastern PIR project will replace existing portions of the lower C-111 canal with a spreader canal to enhance sheetflow to Florida Bay, and restoration efforts within the Southern Glades and Model Lands.

Project Status:

On June 10, 2014, the C-111 Spreader Canal Western Project received congressional authorization in the Water Resources Reform and Development Act (WRRDA) of 2014. Congressional authorization now makes the project eligible for funding during the appropriations process.

In February 2012, SFWMD completed construction of the C-111 Spreader Canal Western Project as part of its state-expedited program. The C-111 Spreader Canal Western Project includes the Frog Pond Detention Area, Aerojet Canal features, plugs in the C-110, a plug at S-20A, and operational changes at S-18C and S-20. A new structure in the lower C-111 Canal is still scheduled for construction in the future.
