Iron Canyon Dam (National ID # CA00417) is a dam in Shasta County, California, United States.

The earthen rockfill dam was constructed in 1965 by the Pacific Gas and Electric Company for hydroelectric power, with a height of 214 feet (65 m) and a length of 1,038 feet (316 m) at its crest.[1] It impounds Iron Canyon Creek. The dam is owned and operated by PG&E. The downstream James Black Powerhouse, one of the largest in the company's system, produces 270 megawatts of power.[2]

Iron Canyon Reservoir

[edit]

The reservoir the dam creates, Iron Canyon Reservoir, is surrounded by the Shasta-Trinity National Forest. It has a water surface of 510 acres (210 ha), a shoreline of approximately 15 miles (24 km), and has a capacity of 24,300 acre-feet (30,000,000 m3).[1] Recreation includes fishing (for trout), hunting, camping,p and hiking.[3]

Water is diverted from the McCloud River at Lake McCloud about 20 miles (32 km) south of Mount Shasta, through a tunnel to Iron Canyon Reservoir, and then through another tunnel to the James B. Black Powerhouse, which outlets into the Pit River on the upper end of Pit Six Reservoir.
