Show Report of the Regional Director 2U. There is urgent need for additional electrical energy in southern Utah, Power requirements in the project area and in the adjacent areas are increasing rapidly* Present facilities will be inadequate to meet those futuro requirements. An additional power supply will need to be obtained either through local development or by importation* The major local potential sources or electrical energy aro hydroelectric development on the Virgin River and steam and diesel developments. Steam and diesel plants consume, of course, nonrcplaceable natural fuels. Plan of Development 25. The Diddle Project would consist of two divisions! the Hurricane Division, which would develop the available water and land resources along the Virgin Rivers and the Santa Clara Division, which would develop these resources along the Santa Clara River. 26. The project plan contemplates furnishing a supplemental water supply to 7,k7O acres of irrigated land in the Hurricane Division, and 1,565 acres in the Santa Clara Division, and development of 11,030 acres of new land in the Hurricane Division and 2,£85 acres of new land in the Santa Clara Division, Hydroelectric power would bo developed at three powerplants, the revenues from which would assist in repaying the reimbursable project costs, 27. The plan of development for the Hurricane Division involves the construction of a dam at the Virgin City site which would create a reservoir of 2U6,OOO acre-feet capacity to control and regulate the flows of the Virgin River for irrigation use and for power production, Thi3 capacity would provide for 180,000 acro-feet of sediment storage in addition to the active capacity required for regulation for irrigation of Hurricane Division lands. The Virgin Powerplant with a capacity of 5,625 kilowatts would be installed at the downstream toe of the dam. Hurricane Division lands would be served through construction of the potential Hurricane main canal, including tunnels, siphons, and drops, which would have a maximum capacity of 330 second-feet, A distribution system would be constructed to serve the new lands in the project, and drainage facilities would be provided whore required. One small pumping plant would be required to serve an area above the main canal* Two powerplants, designated as the Bench Lake and Warner Powerplants would be constructed at drops along the Hurricane main canal and would have capacities of 2,250 kilowatts and 5,U00 kilowatts, respectively.
