Dams on tributaries are listed if they are taller than 250 ft (76 m), store more than 50,000 acre⋅ft (62,000 dam 3), or are otherwise historically notable. Tributary dams are organized into two lists; those in the Upper Basin, defined as the half of the Colorado River basin above Lee's Ferry, Arizona, and the Lower Basin.
The hottest temperature recorded at John Martin Dam was 115 °F (46.1 °C) on July 20, 2019, while the coldest temperature recorded was −27 °F (−32.8 °C) on January 30, 1949, January 18–19, 1984 and February 15, 2021. [8] The 115 °F (46.1 °C) reading is the highest reliably measured temperature ever recorded in the state of Colorado.
Construction on the project, expected to be complete around 2027, [4] will raise the level of the dam by 131 feet (40 meters), resulting in an additional 77,000 acre-feet (95,000,000 cubic meters) of water storage capacity in the reservoir and making it the tallest dam in Colorado. [5]
The tallest is Oroville Dam in northern California, a 770.5-foot (234.8 m) embankment dam completed in 1968. Five of the ten tallest dams in the U.S. are located in California. The Colorado, Columbia and Sacramento–San Joaquin river systems contain the greatest number of tall dams. In the eastern U.S., tall dams are less common because of the ...
Initial plans called for a 100,000 acre-feet (120,000,000 m 3) lake and a 140 foot (43 m) high dam, which would have been the largest earth-filled dam in the world. [4] These plans were revised down during construction, however, with the intention of raising the dam later to its full capacity. Construction began in 1907 and was completed in May ...
