Description    


This project will conduct and alternatives analysis and 100 percent design package for modification of a concrete sill spanning the entire width of the Arroyo Seco River to improve fish passage for the federally threatened South Central Coast steelhead trout. Because the sill is integrated into a diversion canal, the project will also identify the preferred alternative for compliant fish screens and fish by-pass flows. The final product will be 100% designs of the preferred alternative which modifies the existing concrete grade control sill and the associated pre-1914 diversion structure and fish screen.

Project Benefit    


The project will provide for unimpeded fish passage for all life history stages of the threatened native steelhead population while providing the landowners (Clark Colony Water Company) with continued use (diversion) of water consistent with their Pre-1914 rights.
