The proposed rule amendment would amend established minimum water levels for Indian Lake in Volusia County pursuant to the mandate of Section 373.042, Florida Statutes. Each of the amended levels have a duration and return interval. The terms herein are already defined in Chapter 40C-8, F.A.C. As with all minimum levels established by the District, if adopted, the minimum 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.
