- Buckhorn Dam/Grass Valley Creek Toe Drain and Channel Rehabilitation
- Approximately 4,500 cubic yards of sediment will be excavated from the outlet channel for the purpose of lowering the water surface elevation in the dam's toe drain and approximately 4,500 cubic yards of additional sediment and earthen material will be excavated to create and enhance habitat features for Coho salmon including rearing pondsand side channels. Channel creation and enhancement activities are designed to alter the existing center line alignment, create more channel sinuosity, build pool/riffle habitat, lower streambed elevations, increase channel slope, widen the cross-sectional area, and develop inset floodplain benches.
