Historical Context and Alternatives
Reclamation released the SLWRI FEIS, and accompanying Feasibility Report in July 2015. In August 2015 both the FEIS and the Feasibility Report were transmitted to Congress. Both documents evaluated the potential of raising Shasta Dam to increase the following as Project benefits:
- Anadromous fish survival
- Water supply reliability
- Flood damage reduction
- Water quality
- Hydropower generation
- Recreation opportunities
The FEIS and Feasibility Report looked at the benefits for the No-Action and several alternatives.
Alternatives CP-4, CP-4A and CP-5, while similar to CP-3, focus on maximizing different environmental benefits. Ultimately CP-4A was chosen as the Preferred Alternative in both the 2015 FEIS and the Feasibility Report. The information in the SLWRI Draft SEIS does NOT change the alternatives studied under the 2015 FEIS. Instead, the Draft SEIS utilizes the same alternatives, specifically the No-Action and CP-4A Alternatives and updates the environmental benefits analysis for each.
