The San Marcos River in San Marcos, Hays County, Texas is a biologically unique system with several listed species found in
the headwaters. Flowing from the Edwards Aquifer and the second largest spring system in Texas, the water is clear and
thermally constant. The physical and biological character of the habitat within and surrounding the river has been severely
degraded by human activity. As a means of dealing with the continued disturbance and finding a balance between human needs
and conservation, the San Marcos River Habitat Conservation Plan was written as provided by Section 10(a) of the Endangered
Species Act. The plan provides habitat mitigation for the fountain darter (Etheostoma fonticola), Comal Springs riffle
beetle, (Heterelmis comalensis), and San Marcos salamander (Eurycea nana), while allowing for incidental take resulting from
specific restoration and management projects. We used a science-based ecological/experimental approach to address some of the problems and optimize solutions, including restoration of stream banks damaged from overuse, planning for permanent access
points and trails, removal of silt deposits caused by extensive flood control structures, wet-pond construction, managing
flow, and the control of submerged and emergent non-native vegetation to improve habitat and enhance recreation.
