Document Description
The proposed Mono Gate One Facility Upgrade Project consists of (1) construction of an approximately 150-foot bypass pipeline and valve installed to ensure that flows to Lower Rush Creek will not be interrupted. This pipeline will eventually be maintained as a bypass pipeline. (2) Improvements to the Mono Gate structure, installation of equipment (for flow control and monitoring telemetry), and a new measuring station in Rush Creek Return Ditch downstream of the bypass pipeline, and (3) either a new 12 kilovolt overhead power line from the Grant Reservoir shaft house to Mono Gate One along the existing road or a solar power array at the Mono Gate One facility to power operations. The completion of the project will (1) improve the structural integrity of the Mono Gate One Diversion facility; (2) allow for better flow control and measurements from the Grant Reservoir to Lower Rush Creek and Mono Craters Tunnel; and (3) allow for better communications, flow monitoring and flow control between the Mono Gate One facility and LADWP's Bishop facilities.
