Chapter 4 Technical Approach for Establishing Minimum Flows and Levels for the Alafia River, Lithia Springs Major and Buckhorn Springs Main 4.1 Overview Methods used to determine the minimum flow requirements for the freshwater portion of the Alafia River and associated springs are described in this chapter. The approach outlined for the river involved identification of a low flow threshold and development of prescribed flow reductions for periods of low, medium and high flows (Blocks 1, 2 and 3). The low flow threshold was used to identify a minimum flow condition for Block 1, but is expected to be applicable to river flows throughout the year. The prescribed flow reductions are based on limiting potential changes in aquatic and wetland habitat availability that may be associated with changes in river flow during Blocks 1, 2 and 3. Methods used for the springs involved development of prescribed flow reductions based on habitat availability assessments and evaluation of recreational-use requirements. 4.2 Transect Locations and Field Sampling of Instream and Floodplain Habitats The Alafia River study corridor extends approximately 16 miles from Buckhorn Springs near Riverview, Florida, upstream to Aldermans Ford Park (along County Road 39) near the confluence of the North and South Prongs of the Alafia River (Figure 4-1). 4-1
