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]
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.

The Sacramento River is the principal river of Northern California in the United States and is the largest river in California. Rising in the Klamath Mountains, the river flows south for 400 miles (640 km) before reaching the Sacramento–San Joaquin River Delta and San Francisco Bay. The river drains about 26,500 square miles (69,000 km2) in 19 California counties, mostly within the fertile agricultural region bounded by the Coast Ranges and Sierra Nevada known as the Sacramento Valley, but also extending as far as the volcanic plateaus of Northeastern California. Historically, its watershed has reached as far north as south-central Oregon where the now, primarily, endorheic (closed) Goose Lake rarely experiences southerly outflow into the Pit River, the most northerly tributary of the Sacramento.
Shasta Dam is a concrete arch-gravity dam across the Sacramento River in Northern California in the United States. At 602 feet (183 m) high, it is the eighth-tallest dam in the United States. Located at the north end of the Sacramento Valley, Shasta Dam creates Shasta Lake for long-term water storage, flood control, hydroelectricity and protection against the intrusion of saline water. The largest reservoir in the state, Shasta Lake can hold about 4,500,000 acre-feet (5,600 GL).
The Pit River is a major river draining from northeastern California into the state's Central Valley. The Pit, the Klamath and the Columbia are the only three rivers in the U.S. that cross the Cascade Range.
The McCloud River is a 77.1-mile (124.1 km) long river that flows east of and parallel to the upper Sacramento River, in Siskiyou County and Shasta County in northern California in the United States. Protected under California's Wild and Scenic Rivers Act (1972), it drains a scenic mountainous area of the Cascade Range, including part of Mount Shasta. It is a tributary of the Pit River, which in turn flows into the Sacramento River. The three rivers join in Shasta Lake, formed by Shasta Dam north of Redding.
Shasta Lake, also popularly known as Lake Shasta, is a reservoir in Shasta County, California, United States. It began to store water in 1944 due to the impounding of the Sacramento River by Shasta Dam, the ninth tallest dam in the United States.
Trinity Dam is an earthfill dam on the Trinity River located about 7 miles (11 km) northeast of Weaverville, California in the United States. The dam was completed in the early 1960s as part of the federal Central Valley Project to provide irrigation water to the arid San Joaquin Valley.
The Shasta–Trinity National Forest is a federally designated forest in northern California, United States. It is the largest National Forest in California and is managed by the U.S. Forest Service. The 2,210,485 acre forest encompasses five wilderness areas, hundreds of mountain lakes and 6,278 miles (10,103 km) of streams and rivers. Major features include Shasta Lake, the largest man-made lake in California and Mount Shasta, elevation 14,179 feet (4,322 m).
Hell Hole Reservoir is an artificial, crescent-shaped lake in the Sierra Nevada mountain range 10 miles (16 km) west of Lake Tahoe in California, United States. The lake is about 3.5 miles (5.6 km) long when at full capacity.
New Bullards Bar Reservoir is a large reservoir in northeastern Yuba County, California, United States, at an elevation of 2,000 feet (610 m) in the Tahoe National Forest and about 30 miles (50 km) northeast of Yuba City. The 969,600 acre-foot (1.1960×109 m3) reservoir is formed by New Bullards Bar Dam on the North Yuba River, a tributary of the Yuba River. It also receives a portion of the Middle Fork's flow that is diverted to the reservoir via tunnels.
