Body
SUMMARY:
The Anderson Dam Seismic Retrofit Project (ADSRP) progress continues with the development of incorporated Conservation Measures for Coyote Creek.
There are several Conservation Measures for Coyote Creek associated with the Federal Energy Regulatory Commission (FERC) Order Compliance Project (FOCP) and ADSRP to maintain suitable flows in Coyote Creek and enhance natural resources. An update on the ongoing design and construction of the Conservation Measures that are currently moving forward is included below.
- The Coyote Creek Stream Augmentation Fish Protection Measure Project (Chillers) construction contract was awarded and Notice to Proceed was issued on October 4, 2023. During construction of ADSRP, the Chillers will lower the temperature of imported water discharged into Coyote Creek just downstream of the existing dam outlet. The Chillers are expected to be complete in August 2026.
- Just below the Diversion Outlet Structure at the mouth of the Anderson Dam Tunnel (ADT), the south weir in Coyote Creek was completed in December 2025. The north weir was completed in the summer of 2025. The completion of the south weir will allow flows released from Anderson Reservoir through the ADT to be split between the north and south channels of Coyote Creek. The north channel will convey large flow events through the creek, while the south channel will be managed with smaller flows to protect steelhead habitat.
