C.C. Cragin Operation & Maintenance Update:
SRP discontinued pumping from C.C. Cragin Reservoir on July 27 for the 2014 season. The total discharge to the East Verde River for the season was approximately 3,200 acre feet. The following maintenance activities are scheduled:
  • Beginning 9/30/14 SRP will drain the 2 million gallon priming tank to the East Verde River over several days
  • Pipeline drain valves will be opened and drain plugs removed at all crossings for the winter
  • From 9/30/14 to 10/3/14 SRP will open the 24” valve at the bottom of the dam to lower the lake elevation an additional 8’ in preparation for tunnel inlet repair beginning 10/6/14
  • On 10/06/14 a survey crew will complete a USBR required lake elevation survey
  • On 10/07/14 the SRP machine shop will install a new trash rack on the tunnel intake structure

SRP acquired C.C. Cragin (formerly Blue Ridge) reservoir on East Clear Creek from Phelps Dodge Corporation in February 2005 as part of the 2004 Arizona Water Settlement Act. For more history and information on C. C. Cragin, visit our site.

C. C. Cragin Dam is a thin-arch concrete structure with a height of 170 feet and crest length of 492 feet. The watershed above the reservoir is 71.1 square miles. When full, C. C. Cragin Reservoir impounds 15,000 acre feet with a water depth of 100 feet. Water is pumped to the East Verde River via a tunnel, pumping plant, pipeline and related facilities. SRP pumps water at a maximum rate of 35 cubic feet per second from the reservoir during the summer for deliveries to SRP shareholders and, in the future, to Payson and other Northern Gila County communities. The spillway has a maximum capacity of 22,500 cubic feet per second. At minimum pool (elevation 6640 ft) the lake contains 2,165 af of water and is approximately 77 surface acres in size.
