Indian River Lagoon - South

The Indian River Lagoon is considered the most biologically diverse estuarine system in the continental United States and is home to more than 3,000 species of plants and animals. The C-44 Reservoir and Stormwater Treatment Area is the first component of the Indian River Lagoon-South (IRL-S) project, part of the Comprehensive Everglades Restoration Plan (CERP), a joint effort between the U.S. Army Corps of Engineers Jacksonville District and the local sponsor, the South Florida Water Management District.

Based on the feasibility study and PIR approved by Congress in 2007 and further refinements, the project is expected to include the following components:

  • Construction and operation of four new large-scale above-ground reservoirs and their connecting canals, control structures, levees and pumps to capture water from the, C-23, C-24, C-25, and C-44 canals for increased storage. A total combined new water storage of about 130,000 acre-ft (44 billion of gallons) of new storage.  

  • Construction and operation of four new storm-water treatment areas (STAs) (constructed marsh), one for each C-23/C-24 North, C-23/C-24 South, C-25, and C-44 basins, to reduce sediment, phosphorus, and nitrogen entering the SLR estuary and the IRL. A total combined new STAs (constructed marsh) of about 9,100 acres. 

  • Restoration of about 92,100 acres of upland/wetland areas and habitat with ditch plugging, berm construction, and periodic fire maintenance.

  • Redirection of water from the C-23/C-24 basin to the Northfork of the SLR attenuating freshwater flows to the estuary.

  • About 7.9 million cubic yards of muck removal from the SLR’s estuary.  

  • About 900 acres of oyster shell, reef balls, and artificial submerged aquatic vegetation near muck removal sites will be added for habitat improvement.

C-44 Reservoir & Stormwater Treatment Area Project

Construction is underway on the first component of the IRL-S project, the C-44 Reservoir and Stormwater Treatment Area project and will serve a vital role in storing and treating local basin run-off.

Once all contracts are completed, the C-44 Reservoir and Stormwater Treatment Area project will capture local run-off from the C-44 basin, reducing average annual total nutrient loads and improving salinity in the St. Lucie Estuary and the southern portion of the Indian River Lagoon by providing, in total, 60,500 acre-feet of new water storage (50,600 acre-feet in the reservoir and 9,900 acre-feet in the STAs) and 3,600 acres of new wetlands.

The C-44 project includes the construction of a 3,400-acre reservoir, a pump station with a capacity to pump 1,100 cubic feet per second (cfs) of water and 6,300 acres of STAs. Construction on the project's first contract began in 2011 and consisted of constructing the western intake canal, eastern C-133/133A canal, all access roads and staging areas, and the construction of the Citrus Boulevard bridge and culvert. The Corps is scheduled to award the construction contract for the reservoir summer 2015.

All project components were originally planned to be built by the Corps, but in an effort to construct the project as expeditiously as possible, the local sponsor the South Florida Water Management District (SFWMD) is scheduled to award the construction contract for the STAs and a portion of the project discharge canal October 2014, and award the construction contract for the reservoir's pump station April 2015. Construction of the C-44 Reservoir and STA is scheduled to be completed in 2020. Upon construction completion, up to two years of operational testing will occur.
