how much of the colorado river reaches the ocean
Colorado River Flows at the mouth of the river have steadily declined since the beginning of the 20th century, and in most years after 1960 the Colorado River has run dry before reaching the Pacific Ocean.[63] Irrigation, industrial, and municipal diversions, evaporation from reservoirs, natural runoff, and likely climate change, have all contributed to this substantial reduction in flow, threatening the water supply for the future.[64][65][66] For example, the Gila River – formerly one of the Colorado's largest tributaries – contributes little more than a trickle in most years due to use of its water by cities and farms in central Arizona.[67] The average flow rate of the Colorado at the northernmost point of the Mexico–United States border (NIB, or Northerly International Boundary) is about 2,060 cubic feet per second (58 m3/s), 1.49 million acre feet (1.84 km3) per year – less than a tenth of the natural flow – due to upstream water use.[68] Below this point, the remaining flow is diverted to irrigate the Mexicali Valley, leaving a dry riverbed from Morelos Dam to the sea that is supplemented by intermittent flows of irrigation drainage water.[69] There have been exceptions, however, namely in the early to mid-1980s, when the Colorado once again reached the sea during several consecutive years of record-breaking precipitation and snowmelt.[70] In 1984, so much excess runoff occurred that some 16.5 million acre feet (20.4 km3), or 22,860 cubic feet per second (647 m3/s), poured into the sea.[71]
Geographical zone On the basis of latitudinal extent, the globe is divided into three broad heat zones.
Andrea Gail All six of the crew were lost at sea.
Fresh water The majority of fresh water on Earth is in ice caps.
Kentucky River It continues on until it flows into the Ohio River at Carrollton in Carroll County.
Colorado River The Colorado River is one of the principal rivers of the Southwestern United States and northern Mexico (the other being the Rio Grande). The 1,450-mile-long (2,330 km) river drains an expansive, arid watershed that encompasses parts of seven U.S. and two Mexican states. Starting in the central Rocky Mountains in the U.S., the river flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.
