Following is a list of dams and reservoirs in Arizona. All major dams are linked below. The National Inventory of Dams defines any "major dam" as being 50 feet (15 m) tall with a storage capacity of at least 5,000 acre-feet (6,200,000 m 3 ), or of any height with a storage capacity of 25,000 acre-feet (31,000,000 m 3 ).

Arizona's Palo Verde Nuclear Generating Station located to the west of Phoenix is the nation's largest facility by annual energy production, and is the second largest facility by power capacity after Washington state's Grand Coulee Dam hydroelectric station. The electricity generated by utility- and small-scale solar together surpassed the ...
The Hoover Dam in Arizona and Nevada was the first hydroelectric power station in the United States to have a capacity of at least 1,000 MW upon completion in 1936. Since then numerous other hydroelectric power stations have surpassed the 1,000 MW threshold, most often through the expansion of existing hydroelectric facilities.
Although the cost of small hydro projects are generally far lower than large-scale hydroelectric systems, there is a cost to construction. Considering this, if a small hydro project proves to be uneconomical it will have an outsized budget expenditure relative to large projects which run over-budget. [26]
That same year, the dam's pump-generating plant (New Waddell Pump-Generating Plant) began operation. The dam's cost was in excess of $625 million. Large sediment releases from the New Waddell Dam deteriorated the Camp Dyer Diversion Dam 1.25 miles (2.01 km) downstream. This masonry dam had to be rehabilitated by the Bureau in 1992. [3]
The removal of the four hydroelectric dams — Iron Gate Dam, Copco Dams 1 and 2, and JC Boyle Dam — allows the region’s iconic salmon population to swim freely along the Klamath River and its ...
The amount of hydroelectric power generated is strongly affected by changes in precipitation and surface runoff. [4] Hydroelectric stations exist in at least 34 US states. The largest concentration of hydroelectric generation in the US is in the Columbia River basin, which in 2012 was the source of 44% of the nation's hydroelectricity. [5]
