Document Description
North Fork Lost River Flow and Habitat Enhancement (WCB Project ID: 2021039). The Project will restore geomorphic, hydrologic, and ecological processes to about 5,200 feet of Lost River to address limiting factors affecting salmonid production. Stream flow benefits will be achieved through installation of instream channel-spanning structures with subsurface clay restrictive layers and incorporation of a modified Stage 0 approach. Two terrace ponds will be constructed to provide metered flow into the project reach during the lowest flow period between August and October. Channel entrenchment and disconnected floodplains will be reduced and partially eliminated in the reaches designed with channel spanning structures totaling about 3,055 linear feet.
