Slate Creek Dam Sediment Removal and Low-Level Outlet (LLO) Repair Project

The Slate Creek Dam Sediment Removal and Low-Level Outlet (LLO) Repair Project is a maintenance and repair initiative managed by the South Feather Water and Power Agency in Plumas County, California. Part of the South Feather Power Project, FERC Project No. 2088, this work is mandated by the California Department of Water Resources, Division of Safety of Dams (DSOD). The primary objective is to restore the functionality of the low-level outlet, which is currently non-functional due to sediment accumulation. The scope of work includes the removal of approximately 9,200 cubic yards of sediment and the diversion of flows to facilitate the necessary repairs to the dam facility. The project is classified under NAICS code 237990 and is exempt from certain environmental reviews under Section 15301 as it involves the maintenance of existing facilities without expanding current use. Administrative approval was granted via Board Resolution 26-06-04, and a Notice of Exemption was filed in July 2026. Key personnel overseeing the project include Regulatory Compliance Manager Kristen McKillop and Power Division Manager Hunter Doyle. Performance will take place at the Slate Creek Diversion Dam located in Strawberry Valley.
