The C-44 Reservoir and Stormwater Treatment Area (STA) Test Cells Project was constructed due east of Lake Okeechobee in southern Martin County, Florida. The intent of the project was to field-test two reservoir designs and STA systems before actually building the much larger C-44 Reservoir, slated as part of Florida's "Acceler8" Program. The Program has been designed to eliminate environmental damage to the Everglades resulting from high phosphorus and turbidity levels contained in the inflows from Lake Okeechobee. The C-44 Test Cells Project involved the construction of two temporary reservoirs and two temporary STAs through which the SFWMD could evaluate seepage rates, water quality, and availability and usefulness of onsite materials. The two reservoir test cells were built with 21-foot embankments to hold a maximum water depth of 15 feet. They cover approximately 12 acres each. The two STAs hold about 2 feet of water within embankments built 3.5 to 5 feet high. The two reservoir test cells differ from each other in design to help SFWMD develop a final design for the larger C-44 Reservoir. Test Cell #1 included a blanket and chimney drain system composed of sand and PVC drain piping within the center of the embankment. Test Cell #2 contained a similar blanket drain system, with the addition of an HDPE liner within the center of the embankment and a soil-cement cap on the outside of the embankment.
