Valencia Creek Fish Ladder

valencia2-postClient: Santa Cruz County Community Action Board

Waterways staff was retained to develop a fish passage improvement design for a concrete culvert that was hindering fish passage on Valencia Creek, in Santa Cruz County. Plans were developed to construct a concrete fish ladder structure, per design criteria established by the National Marine Fisheries Service (NMFS) and the California Department of Fish and Game (CDFG).

Our staff performed detailed hydrologic, hydraulic and structural calculations to create a functional, constructable, and structurally appropriate design suited to the site’s difficult access and high energy environment. The design consists of a structural concrete fish ladder, founded on deep piers penetrating bedrock, sized to resist the high sediment load and significant hydraulic stresses present at the site.
