Document Description
The project is comprised of two separate but interrelatd components: a water conveyance tunnel from Nacimiento Reservoir to San Antonio Reservoir, and modifications to the existing spillway at San Antonio Reservoir. The project includes the following elements: Interlake Tunnel (gravity flow), Tunnel Intake Structure at Nacimiento Reservoir, Energy Dissipation Structure at San Antonio Reservoir, San Antonio Dam Spillway Modification, and disposal of spoils. The proposed modifications of the spillway at San Antonio Reservoir would provide a 7 foot increase in the maximum reservoir elevation, effectively increasing the storage capacity of the reservoir by approximately 41,000 acre-feet.
