Homosassa River Surface Water Improvement and Management (SWIM) Plan A Comprehensive Conservation and Management Plan August 2017 Homosassa River SWIM Plan Homosassa River SWIM Plan Springs Coast Steering Committee Members Each spring system in the Springs Coast region is a unique, complex system with different sets of challenges. To address these issues, the Springs Coast Steering Committee (SCSC) was formed of local, regional and state agencies. The first goal of the SCSC is to develop management plans tailored for each spring system to identify issues, objectives, projects and responsibilities. This document serves as satisfaction of that first goal for the Homosassa River. The Southwest Florida Water Management District (District) does not discriminate on the basis of disability.
