Helping the City of Lincoln balance growth with environmental compliance to enhance spawning habitat for federally listed species

The City of Lincoln is a rapidly growing community in the Yosemite Valley, California. A result of this growth are impacts to fish spawning habitat in the region, especially for the federally listed threatened species the Central Valley steelhead. The Village 1 Phase 1 Environmental Compliance Plan was created to respond to anticipated growth and demand for housing and services in the area. As part of this plan, our biologists and engineers are working together to design and install a fishway allowing for downstream volitional fish passage in a disconnected artificial floodway. The floodway converges with Auburn Ravine, which is designated critical habitat for Central Valley steelhead.   

We are working closely with developers, the California Department of Fish and Wildlife, and the National Marine Fisheries Service to obtain permits to begin construction in the floodway. While the floodway is disconnected, our biologists have been conducting water quality monitoring (temperature and dissolved oxygen) and fish monitoring in the floodway to determine that fish can rear until their next opportunity to return to Auburn Ravine through the inlet or outlet.

Once construction is completed, the floodway will have full connectivity for fish passage from the inlet to the outlet. The goal is for this artificial floodplain to become beneficial seasonal rearing habitat for steelhead and other species.
