Collectively, the short and long-term compliance standards proposed for the USGS gage site at Lithia comprises the District's proposed minimum flows and levels for the Alafia River. The standards are intended to prevent significant harm to the water resources or ecology of the river that may result from water use. Since future structural alterations could potentially affect surface water or groundwater flow characteristics within the watershed and additional information pertaining to minimum flows development may become available, the District is committed to revision of the proposed levels, as necessary. A minimum flow recommendation was developed for Buckhorn Spring based on a PHABSIM analysis of Buckhorn Creek. It was determined that Buckhorn Spring flow should not be reduced by more than 15% to ensure no more than a 15% reduction in fish habitat in Buckhorn Creek. Flows from Lithia Spring were evaluated using a recreational standard (for bathing places) and a PHABSIM analysis of the short spring run between the spring and the Alafia River. The recreational standard would allow considerable reductions in flow before being violated; however, the PHABSIM analysis indicates that no more than a 5% reduction in flow is allowable before a 15% loss of fish habitat in the run occurs. The spring run is small and offers no unique fish habitat that does not exist in the main channel of the Alafia River. Because flow from these two springs may be an important component of downstream estuarine flow requirements, we have refrained from recommending minimum flows for Buckhorn Spring and Lithia Springs until the MFL assessment for the estuarine portion of the river is complete. xvi
