Section 373.042, F.S., requires the District to establish minimum flows and levels for lakes, wetlands, rivers and aquifers within the District’s boundaries. Section 373.0421(3), F.S., further requires the District to periodically reevaluate and revise adopted minimum flows and levels. This rulemaking is necessary to delete the previously adopted levels, and adopt new guidance and minimum levels for Moon Lake located in Pasco County. The establishment and periodic evaluation of minimum levels is required by statute to ensure that the minimum hydrologic requirements of the water resources and ecology of this lake are maintained. The revised minimum and guidance levels for Moon Lake are being developed using previously peer-reviewed, Governing Board adopted methods.
