Twin Lakes Enlargement and Rehabilitation

Document Type: Proceeding Paper

Part of: Geotechnical Practice in Dam Rehabilitation

Abstract:

The Twin Lakes Enlargement and Rehabilitation Project involves an enlarged embankment replacing a two-tiered reservoir system with a single, larger-volume reservoir and new appurtenances. By raising the dam crest to an elevation higher than the two existing dams, the reservoir capacity will be increased. A labyrinth spillway will increase the spillway capacity to handle the probable maximum flood (PMF). A new telemetry system will help reduce the waste of city water by allowing remote control of the outlet works. This paper describes how the project was designed to take advantage of the existing glacial topography and optimize the use of on-site glacial materials. Design of the spillway and outlet works are also discussed.
