Abstract : The recommended improvement to the existing flood control Prado Dam, which was completed by Corps of Engineers in 1941, consists of enlarging the reservoir capacity by raising the spillway crest 20 feet and the top of the dam 28.4 feet to elevations 563 and 594.4 feet, respectively. A new gated outlet structure capable of releasing 30,000 cubic feet per second, an auxiliary dike, and a dike along the Corona Expressway would be provided. Approximately 1,660 acres of land up to elevation 566 feet would be acquired for the enlarged reservoir. Interior dikes would be provided for the protection of the existing facilities at the Corona Sewage Treatment Plant, Alcoa Aluminum Plant, Corona Housing Tract, and California Institution for Women. The cost for the recommended improvement is estimated at $212,623,000, including $116,274,000 for land acquisition. (fr)
