The Water Resources Development Act of 2000 (WRDA 2000) requires the State of Florida to reserve or allocate water for the natural systems associated with implementation of CERP projects. The District proposes to establish a water reservation for natural system water associated with the CERP Biscayne Bay Coastal Wetlands Project (Phase 1) to identify and reserve water from consumptive use and to ensure that water is available to provide the intended benefits to the natural system. The Water Reservation rule will require consumptive use permit applicants to provide reasonable assurances that their proposed use of water will not withdraw water reserved for the natural system.
