East Highline Reservoir Project (Request for Proposal)

Description: Construct a 2,100 acre-foot (ac-ft) off-line storage reservoir and 1.8-mile long Intake Canal. The EHR Project will provide operational storage by having the ability to divert water from the AAC, store it, and release it to the EHL Canal. The proposed reservoir will provide a non-jurisdictional maximum water storage depth of 6 feet (ft), and receive flow from the proposed Intake Canal connection at the AAC Hydro Pond. The Intake Canal will be a 1.8-mile trapezoidal-shaped lined channel with 3H:1V side slopes, and capacity of 1,500 cubic feet per second (cfs). Water from the reservoir will be released to the EHL Canal through a 1,000-foot long trapezoidal-shaped lined channel and emergency spillway with 3H:1V side slopes, and capacity of 1,000 cfs. The AAC Tie-In, reservoir inlet and outlet structures will be gated control. The reservoir will be operated to fill and release within 24-hour cycles.
