Section 373.042, F.S., requires the District to establish minimum flows and levels for water bodies located 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 rule is necessary to revise the previously established minimum flows for the Chassahowitzka and Homosassa River Systems and associated springs in Citrus County. The establishment and periodic evaluation of minimum flows is required by statute to ensure that the minimum hydrologic requirements of the water resources and ecology of this spring group are maintained. The establishment of minimum flows for the Chassahowitzka and Homosassa River Systems are being developed using previously peer-reviewed, Governing Board adopted methods.
