DWR will remediate rodent burrows at Clifton Court Forebay, Dyer Reservoir, and Patterson Reservoir and implement other maintenance and repair activities for the project facilities to improve the stability and safety of each dam. The Project involves collapsing and/or excavating burrows, backfilling the dam surface, and compacting the soil, as well as placing wire and/or rock to provide permanent armoring in some locations.
