Report
Summary
The parties are entities that are entitled to use spill water from Roosevelt Dam on the Salt River. The parties are proposing a change to the Water Control Plan that governs operations of the flood control space at Roosevelt Dam. The proposed changes to the Water Control Plan contemplate planned instances to allow deviations from normal dam regulation in order to maximize reservoir and water use. Under provisions of section 7-14(c) or the Water Control Plan and section 7 of the Water Control Agreement, Salt River Project (SRP), Reclamation, and the Corps of Engineers developed a planned deviation wherein SRP, among other things, is authorized to extend the evacuation period for water entering the first five feet of the Flood Control Space on a five-year pilot basis. By extending the evacuation period, the participating entities will have greater access to use flood waters impounded behind Roosevelt Dam. Phoenix will have access to the largest volume of 18.41 percent.
Contract Term
The agreement will begin on or about Oct. 1, 2022 for the length of the pilot project, or five years and 120 days, whichever is shorter.
Financial Impact
The aggregate value of the agreement is not to exceed $26,000.
Funding for this contract is available in the Water Services Department's Operating budget.
