Under consideration are: (1) Increasing the capacity of the existing generator units; (2) Adding large units to the end of the penstocks; and (3) Adding reversible pump generators to the end of the penstocks. A peaking power needs survey initiated in May 1977, with a questionnaire sent to approximately 90 entities to determine their future peaking requirements, has been completed. ¦ C. Parker-Davis Project C. 1 Background The Parker Dam and Davis Dam power projects were authorized and constructed separately. The Parker Dam power project was authorized under the Rivers and Harbors Act of August 30, 1935 (Public Law 409, 74th Congress, 1st session, 49 Stat. 1028). The Davis Dam project was authorized under the Reclamation Act of 1939 (53 Stat. 1187), when a finding of feasibility was made by the Secretary of the Interior on April 26, 1941. Their consolidation into the Parker-Davis Project was authorized by Act of May 28, 1954 (68 Stat. 143). The primary purpose of the Parker Dam was to provide a forebay from which The Metropolitan Water District of Southern California could pump water into its Colorado River Aqueduct. The dam was constructed with funds advanced by The Metropolitan Water District (MWD). Parker Dam Powerplant was later added to provide low cost electrical energy to Arizona and southern California. Power generation started on December 13, 1942. MWD is entitled to one-half of the power generated at Parker Dam. |
