Site 1 Impoundment (Fran Reich Preserve)
Project Mission:
Construct reservoir and water conveyance features
Project Benefits:
Store water that would otherwise flow to the Atlantic Ocean. Benefits include increased water supplies for the natural environment, people and farms; habitat restoration; improvements to Lake Okeechobee and the coastal estuaries; groundwater recharge; reduced saltwater intrusion; and decreased seepage out of the Everglades.

Project Description
The purpose of this project is to supplement water deliveries to the Hillsboro Canal by capturing and storing excess water currently discharged to the Intracoastal Waterway. These supplemental deliveries will reduce demands on Lake Okeechobee and LNWR. The impoundment pool will also provide groundwater recharge, reduce seepage from adjacent natural areas, and prevent saltwater intrusion by releasing impounded water back to the Hillsboro canal when conditions dictate. Some measure of flood protection may also be provided along with water quality improvements. This project includes canal and structure relocations, canal conveyance improvements, water control structures and an aboveground impoundment with a total storage capacity of approximately 13,280 acre-feet located in the Hillsboro Canal Basin in southern Palm Beach County. The design of the impoundment includes two compartments totaling 1,660 acres with water levels fluctuating up to 8 feet above grade. North Springs Improvement District flows were redirected from Water Conservation Area (WCA) 3 northward via the L-36 Borrow Canal to the Hillsboro Canal where the volume can be pumped into the impoundment. The conveyance of the Hillsboro Canal was increased from the impoundment inflow structure east to the LWDD E-1 canal to allow backpumping of additional flows from the western Hillsboro Canal basin. An ASR system within the impoundment was also modeled and proved to be beneficial for long-term storage and meeting water supply demands. |
