Funding for this Project will be used to generate 65% fish passage design plans to modify the Marre Weir, the most downstream barrier in San Luis Obispo Creek, while continuing to protect upstream water supplies from seawater intrusion. The Project is necessary to modify and improve passage of primarily Steelhead trout, Pacific lamprey, stickleback and sculpin. Design plans will also include Steelhead Life Cycle Monitoring Station development and placement. Biological assessments, wetland delineation and hydraulic modeling will be conducted to inform project designs and permit applications which will be developed and submitted to the appropriate agencies at the 65% phase.
Central Coast Salmon Enhancement
Specific objectives of this Project are to:
(1) Complete 30% and 65% fish passage and weir structural design plans to improve fish passage at the site and protect upstream water supplies from seawater intrusion;
(2) Conduct hydraulic modeling to inform designs and permitting;
(3) Improve downstream habitat for fish and wildlife by considering step pool and habitat enhancements in the design allowing for improved movement of water and materials for more natural channel forming flows and function
(4) Improve local watershed management and monitoring by designing an integrated monitoring station that would be compatible with steelhead trout population monitoring as outlined in California Coastal Plan,
