Until the MFL proposed in 40D-8.041(19), F.A.C., becomes effective, this emergency rule will temporarily establish minimum water flow for the Rainbow River System, an Outstanding Florida Spring, pursuant to the mandate of section 373.042, F.S. The minimum flow for the Rainbow River System was developed utilizing the percent-of-flow approach and is expressed in cubic feet per second as a long-term average flow adjusted for groundwater withdrawals from 1965 to 2015 at the USGS Rainbow River at Dunnellon, FL Gage. As with all minimum flows and levels established by the District, if adopted, the minimum flow in this rule would be used as a basis for imposing limitations on withdrawals of groundwater and surface water in the water use permitting regulatory process and for reviewing proposed surface water management systems in the environmental resource permitting regulatory process.
