Control Gorge Camp Bank Stabilization Biowall (Notification of Lake or Streambed Alteration, No. EPIMS-INY-60537-R6)

The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement EPIMS-INY-60537-R6 for the Los Angeles Department of Water and Power. This project involves the construction of a bioengineered bio-retaining wall measuring approximately 120 feet long by 16 feet wide to stabilize and reconstruct a portion of the Owens Riverbank in Inyo County, California. The wall will be built using a combination of construction materials, such as dead man anchors and a granular filter, and native, locally-sourced materials including Bishop tuff, soil, and coyote willow pole cuttings. Following the completion of the wall, the road located atop the reconstructed bank will be repaired. The project is conducted pursuant to Section 1602 of the Fish and Game Code and is categorized as exempt under the California Environmental Quality Act through Class 1 and Class 3 exemptions. The work is located at the Owens River, a tributary to Owens Lake, specifically at latitude 37.43627 and longitude -118.55602. Administrative oversight is managed by the California Department of Fish and Wildlife Region 6, with primary points of contact including Cooper Wall and Marshall Cyr. The project is classified under NAICS code 237990.
