The proposed rule would revise the established minimum surface water levels for Lake Melrose, Lake Norris, and Lake Purdom pursuant to the mandate of Section 373.042, Florida Statutes. Each revised surface water level has an associated duration and return interval. The terms herein are already defined in Chapter 40C-8, F.A.C. As with all minimum surface water levels established by the District, if adopted, the minimum surface water levels in this rule amendment would be used as a basis for imposing limitations on withdrawals of groundwater and surface water in the consumptive use permit regulatory process and for reviewing proposed surface water management systems in the environmental resource permit regulatory process.
