The Colorado River (Spanish: Ro Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern Mexico.The 1,450-mile-long (2,330 km) river drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. - Records, 1900-2021: All temperatures are listed in Fahrenheit. The environmental movement in the American Southwest has opposed the damming and diversion of the Colorado River system due to negative effects on the ecology and natural beauty of the river and its tributaries. University of California, Irvine 1988. --- Hottest summer: 1936 (78.6 degrees; 4.1 degrees above norm) * Use the near real-time water temperature data with discretion, because they may contain errors. --- Coldest year: 1904, 37.9 degrees (3.4 degrees below norm) Temperatures are measured on the coast, so these are swimming temperatures. b. --- Coldest year: 1976, 49.3 degrees (2.7 degrees below norm) [192][194][n 7], About 40million people depend on the Colorado River's water for agricultural, industrial and domestic needs. Today, the C-BT is the largest of the transmountain diversions, delivering 230,000 acre-feet (280,000,000m3) per year from the Colorado River to cities north of Denver. However, it dropped to 8 C (46.4 F) in July 1999. [86], As of 2010, approximately 13million people lived within the Colorado River basin,[n 6] while about 40million people live in areas supplied by Colorado River water. --- Average low: 62.2 degrees (2.8 degrees above norm) For that, the temperature needs to be low enough for the air to act as a kind of refrigerant, drawing heat off the skin so the engine can keep pumping. --- Average high: 63.5 degrees (1.4 degrees above norm) However, it dropped to 8 C (46.4 F) in July 1999.

The average maximum daytime temperature lies around 26.9C (80.42F). The Grand Ditch, directing runoff from the river's headwaters across the Continental Divide to arid eastern Colorado, was considered an engineering marvel when completed in 1890. [14][15] In a few areas, such as the marshy Kawuneeche Valley near the headwaters[16] and the Grand Valley, it exhibits braided characteristics. --- Average high: 74.7 degrees (0.7 degrees above norm) --- Hottest summer: 1936 (72 degrees; 5.7 degrees above norm) --- Average high: 72.8 degrees (1 degree above norm) --- Average high: 55 degrees (4.1 degrees above norm) The ideal temperature for freezers is 0 Fahrenheit.

The pumping power was replaced by the building of the coal-fired Navajo Generating Station near Page, Arizona, in 1976. In time, flash floods caused significant downcutting on irrigation canals, which in turn led to the entrenchment of the original streams into arroyos, making agriculture difficult. --- Coldest winter: 1905 (27.6 degrees; 7 degrees below norm), - 2021 temperatures: [61] Tributaries in the Lower Basin are prone to monsooncaused flash floods, but these storms do not often contribute significant volumes of runoff.

Ultimately, a compromise was reached, with Arizona dropping its objections in exchange for the USBR constructing the Gila Project, which irrigates 110,000 acres (450km2) on the Arizona side of the river. Explorer, and traveled up the river as far as Black Canyon. - Records, 1900-2021: The Colorado River (Spanish: Ro Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern Mexico.The 1,450-mile-long (2,330 km) river drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. Know the moment your prices lose their competitive edge.

Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the ArizonaNevada border, where it turns south toward the international border. [237] The Upper Basin states were concerned that they would not be able to use their full Compact allocations due to increasing water demands in the Lower Basin.
