Conclusion: After three years of research, the Army Corps of Engineers finds that the final option Toulumne River/Lake Eleanor would be the best option for the new dam. We found that 9 of these sites meet the first three criteria for the proposed dam. We have determined that Hetch Hetchy will be $20,000,000 less expensive than the other final nine options. Electric power can easily be generated at this site and sold to pay for some of the costs.
