The Jacksonville District, U.S. Army Corps of Engineers (Corps) is beginning preparation of a National Environmental Policy Act assessment for the Lake Okeechobee Watershed Project (LOWP). The Everglades ecosystem, including Lake Okeechobee, encompasses a system of diverse wetland landscapes that are hydrologically and ecologically connected across more than 200 miles from north to south and across 18,000 square miles of southern Florida. In 2000, the U.S. Congress authorized the Federal government, in partnership with the State of Florida, to embark upon a multi-decade, multi-billion dollar Comprehensive Everglades Restoration Plan (CERP) to further protect and restore the remaining Everglades ecosystem while providing for other water-related needs of the region. CERP involves modification of the existing network of drainage canals and levees that make up the Central and Southern Florida Flood Control Project. One of the next steps for implementation of CERP is to identify opportunities to restore the quantity, quality, timing and distribution of flows into Lake Okeechobee. The LOW Project preliminary project area, where placement of features will be considered, covers a large portion of the Lake Okeechobee Watershed north of the lake. Water inflows into Lake Okeechobee greatly exceed outflow capacity, thus many times there is too much water within Lake Okeechobee that needs to be released in order to ensure integrity of the Herbert Hoover Dike. At other times, there may be too little water within Lake Okeechobee. Lake levels that are too high or too low, and inappropriate recession and ascension rates, can adversely affect native vegetation, and fish and wildlife species that depend upon the lake for foraging and reproduction. The volume and frequency of undesirable freshwater releases to the east and west lowers salinity in the estuaries, severely impacting oysters, sea grasses, and fish. Additionally, high nutrient levels adversely affect in-lake water quality, estuary habitat, and habitat throughout the Greater Everglades. The objectives of the LOW Project are to improve the quality, quantity, timing and distribution of water entering Lake Okeechobee, provide for better management of lake water levels, reduce damaging releases to the Caloosahatchee and St. Lucie estuaries downstream of the lake and improve system-wide operational flexibility.
