A Environmental Topics summary by the ENVS 560/L Watershed Systems class at CSUMB.

This page provides a brief overview of the history, timeline of events, EIR Development, contract documents and county presentations for the proposed Interlake Tunnel.

Overview

The primary purpose of the Interlake Tunnel was to redirect water from the Nacimiento Reservoir to the San Antonio Reservoir in efforts to reduce spillage at the Nacimiento Dam. Based on historical data, the Nacimiento River basin produces roughly three times the average flow of the San Antonio River basin. To increase the overall capacity of the system, the Interlake Tunnel could capture high Nacimiento River flows and reroute them to the San Antonio Reservoir.[1]

The Monterey County Water Resources Agency (MCWRA) prioritized the completion of the Salinas Valley Water Project (SVWP) and the Salinas River Diversion Facility before the Interlake Tunnel Project.[2]

Specifications

The tunnel is designed to be approximately 11,000 feet long and used gravity flow dynamics that has an inflow situated at the Nacimiento Reservoir and an outflow built in the San Antonio Reservoir. The total project is estimated to cost $50 million and could be completed by 2022.

The Monterey County Water Resources Agency (MCWRA) expressed priority in a preliminary environmental review before moving beyond pre-construction tasks. Pre-construction costs are imaged here.
