2. How can you explain the fact that the Colorado River course pays no heed to the NW-SE Moab Valley? (This observation by early explorers in the area caused the structural extension of the Moab Valley to be called the “Paradox Basin”.) 3. What is the origin of the Moab Valley, if it was not carved by the river?
The Colorado River is a major river of the western United States and northwest Mexico in North America. Its headwaters are in the Rocky Mountains where La Poudre Pass Lake is its source. Located in north central Colorado it flows southwest through the Colorado Plateau country of western Colorado, southeastern Utah and northwestern Arizona where it flows through the …
Apr 22, 2021 · An acre-foot, explained. (Now multiply by 7.5 million.) credit: Catalina Islander The predicted flow of the Colorado River—16 million acre-feet a year —was thought to be a conservative estimate in 1922, but the 1910’s were freakishly wet years, so the estimate was actually too generous; recent estimates are closer to 13 million. (From this simple mishap …
The damming and diverting of the Colorado, the nation’s seventh-longest river, may be seen by some as a triumph of engineering and by others as a …
The Colorado River no longer reaches the Gulf, and instead peters out of existence miles short of the sea. Two factors have conspired to turn this once mighty river into a trickle: climate change and overuse by the very states that rely on its waters. A section of the Colorado River.Aug 2, 2020
Dams along the Colorado River's length in the U.S. and Mexico draw its water away to serve farms and cities throughout the region. Rather than emptying into the ocean, its water grows citrus in Arizona and greens up lawns in Los Angeles.Jul 30, 2021
It irrigates over 5 million acres of agricultural land – supplying a majority of carrots, lettuce, and other vegetables in the winter to U.S. consumers. It provides hydropower and supports a $26 billion recreation economy.Sep 15, 2018
Once the source areas for the rivers were uplifted, erosion in the form of glaciers and precipitation (rain) began to cut away at the land. How does a river form? As water runs downhill, the force of the water and abrasion from sediment that it carries with it, cut into the soil, forming channels.Jun 26, 2017
The Colorado River is the 47th longest river in the world. The average depth of the Colorado River is around 20 feet. The deepest point of the Colorado River is around 85 feet. The Hoover Dam was built on the Colorado River between 1931 and 1936.
DENVER — The headwaters of the Colorado River are just a small stream in the mountains of northern Colorado. The water comes from a lake on the Poudre Pass in Rocky Mountain National Park and then flows out to Grand Lake and Lake Granby. It's in Granby where much of the water gets diverted.Jul 12, 2021
melting Rocky Mountain snowpackThe primary source of Colorado River water is melting Rocky Mountain snowpack. Once the river descends from the Rockies, it flows through a landscape that is dominated by desert.
Scientists estimate the canyon may have formed 5 to 6 million years ago when the Colorado River began to cut a channel through layers of rock. Humans have inhabited the area in and around the canyon since the last Ice Age.Sep 29, 2020
Grand Rapids gets its name from the many sets of rapids formerly located in the Grand River at the present site of the city. These were smoothed out, during a series of "urban renewal" moves during the 1960s, by a series of small dams.
When and how does the shape of a river change? A river changes shape as it flows from its source to its mouth. The shape of both the long profile (a slice through the river from source to mouth) and the cross profile (a slice across the river) changes.
Today, the Colorado River is still used for irrigation , but it is also used to generate hydroelectric power and to supply water to distant urban areas. The Colorado River has been a central feature in the history and development of the American West.
How is the Colorado River Basin divided? The Colorado River Compact divided the Colorado River Basin into the Upper Basin and the Lower Basin. The division point is Lees Ferry, a point in the mainstem of the Colorado River about 30 river miles south of the Utah-Arizona boundary, just downstream of Glen Canyon Dam.Mar 12, 2015
The Colorado forms the border of California to the west and Arizona to the east for most of its course through the desert Lower Colorado River Valley (LCRV), where its character changes significantly from fast-flowing whitewater to a low gradient braided stream with a wide floodplain.
Before an act of Congress changed the name in 1921 this confluence marked the official beginning of the Colorado River proper. The approximately 450 miles (720 km) of the Colorado above the confluence of the Green, including the entire section within Colorado, was known as the Grand River.
Below the Green River the Colorado flows through Cataract Canyon, which contains some of its most difficult rapids. At Hite the Hite Crossing Bridge – the only bridge over the Colorado for nearly 300 miles (480 km) – carries Utah State Route 95 over the river.
The Colorado River is a major river of the western United States and northwest Mexico in North America. Its headwaters are in the Rocky Mountains where La Poudre Pass Lake is its source. Located in north central Colorado it flows southwest through the Colorado Plateau country of western Colorado, southeastern Utah and northwestern Arizona where it flows through the Grand Canyon. It turns south near Las Vegas, Nevada, forming the Arizona– Nevada border in Lake Mead and the Arizona– California border a few miles below Davis Dam between Laughlin, Nevada and Needles, California before entering Mexico in the Colorado Desert. Most of its waters are diverted into the Imperial Valley of Southern California. In Mexico its course forms the boundary between Sonora and Baja California before entering the Gulf of California. This article describes most of the major features along the river.
Then the river then turns abruptly west directly across the folds and fault line of the plateau, through the Upper and Lower Granite Gorges of Grand Canyon, which is 217 miles (349 km) long and from 4 to 20 miles (6.4 to 32.2 km) between the upper cliffs.
The Grand Ditch redirects water from the Never Summer Mountains, which would have flowed into the Colorado River, to instead flow across the divide through La Poudre Pass to irrigate farmland to the east. Near the source of the Colorado River in Rocky Mountain National Park, Colorado. About a mile (1.5 km) downstream from its source, ...
Lake Mead, formed by the 726-foot (221 m)-high Hoover Dam about 30 miles (48 km) southeast of Las Vegas, Nevada, is the largest reservoir in the United States with a full capacity of 28,945,000 acre-feet (35.703 km 3) and a water surface of nearly 250 square miles (650 km 2 ).
In Spring 2021, I road-tripped the Southwest to better understand the Colorado River: the dams, the diversions, and the different populations it serves.
The very first users of the Colorado, amazingly enough, are right at the river’s headwaters. They’re actually east of its headwaters, in Colorado’s Front Range.
If you took a plane and traced the path of the Colorado starting at its headwaters, it would remain a small, modest river for much of its journey…
After passing through the Grand Canyon, the river slows once again, thanks to Hoover Dam: the biggest and baddest development on the entire Colorado.
The Colorado River now heads due south, beelining for Mexico, but soon transforms in Lake Mojave, a small reservoir created by Davis Dam.
Continuing south, the river now straddles the border of Arizona and California, becoming wider and shallower, and feels more domesticated as houses and RVs line the shores. River-irrigated farmlands surround the small city of Needles, CA, where flooding destroyed a local bridge three times before Hoover Dam was erected.
As the Colorado makes its way down the California/Arizona border, two tiny dams—Headgate Rock and Palo Verde—divert part of the river into irrigation canals for the Parker and Palo Verde Valleys. These are called “diversion dams” because they don’t create reservoirs, they simply divert the water.
And boaters still roar across Nevada and Arizona’s Lake Mead, 110 miles long and formed by the Hoover Dam. But at the lake’s edge they can see lines in the rock walls, distinct as bathtub rings, showing the water level far lower than it once was—some 130 feet lower, as it happens, since 2000.
Almost all wastewater is reused or returned to the Colorado River. In 1922, conservationist Aldo Leopold paddled a canoe through the great delta at the mouth of the Colorado River. He wrote about a “wealth of fowl and fish” and “still waters...of a deep emerald hue.”.
With over 150 golf courses and a continuing expansion into the desert, greater Phoenix continues to be a large consumer of water. (Peter McBride) The Colorado River winds through Rocky Mountain National Park. (Peter McBride) The Colorado meanders for nearly 1,500 miles across seven states.
Peter McBride has spent two years photographing the great river, paddling a kayak through its headwaters, flying in small planes over cities and fields, rafting through the Grand Canyon and using his own two feet to traverse the delta.
Sarah Zielinski is an assistant editor for Smithsonian. Peter McBride ’s book The Colorado River: Flowing Through Conflict will be published in November 2010. In a potash mine near Moab, Utah, the water is dyed blue to speed evaporation. (Peter McBride) Reservoirs along the river may never rise to previous levels.
During the Nazi occupation of France, many valuable works of art were stolen from the Jeu de Paume museum and relocated to Germany. One brave French woman kept detailed notes of the thefts
More than one billion people around the world now live in water-stressed regions, according to the World Health Organization, a number that is expected to double by 2050, when an estimated nine billion people will inhabit the planet.
The width here is merely 76 feet. ▶ It flows through 7 states, Colorado, New Mexico, Utah, Arizona, Wyoming, California, and Nevada. ▶ The name Colorado originates from the Spanish word for red color. This is because of the red sandstone silt that would cover the river basin, making it look red.
The earliest settlers along the Colorado River Basin are believed to be the Paleo-Indians, who belonged to the Clovis and other cultures. They are estimated to have landed up at this location over 12,000 years ago.
▶ Four critically endangered fish species, the Humpback Chub, the Bonytail, the Razorback Sucker, and the Colorado Pikeminnow, reside in this river.
▶ The first ever dam to be built on the river was the famous Hoover, in 1935. This dam is 726.4 feet (221 meters) high.
This dam is 726.4 feet (221 meters) high. ▶ One of the nicknames given to this river is River Of Law, because of the high number of legal disagreements over its water. Now, nearly all the water of the river is controlled. ▶ The river stopped looking red in 1963, after the construction of the Glen Canyon Dam.

Tribal members are fighting against a Trump administration oil and gas leasing plan that could bring fracking to the doorstep of Chaco Canyon in New Mexico, home to historical artifacts sacred to Navajo and Puebloan people, per the Guardian’s Cody Nelson.
Nowhere is that more true than the Imperial Valley, a sun-baked desert in California’s southeastern corner where around 500 landowning families use Colorado River water to grow much of the country’s winter vegetables. I’ve spent lots of time there as a reporter.
Abatti’s attorney, Cheryl Orr , said farmers have a right to however much water they “reasonably need” to cultivate their crops, based on past use. (Farmers currently use 97% of the Imperial Valley’s water.) Orr told the judges that under established law, farmers “have a priority of water that is different and higher than just an ordinary use,” such as household drinking water.
Sammy Roth covers energy for the Los Angeles Times and writes the weekly Boiling Point newsletter. He previously reported for the Desert Sun in Palm Springs. He grew up in Westwood and would very much like to see the Dodgers win the World Series again.
A state court told San Diego County it can’t let housing developers avoid reducing climate pollution from new car traffic by using “carbon offsets” that might reduce emissions in other states, or even other countries. Here’s the story from Joshua Emerson Smith at the San Diego Union-Tribune. This is the sixth time a court has rejected the county’s climate action plan.
Pacific Gas & Electric is finally exiting bankruptcy. But is the company any better positioned to prevent wildfires and stop killing its customers? I took an in-depth look at the utility’s reorganization plan, and found the new PG&E looks a lot like the old PG&E. (Also this week, PG&E pleaded guilty to 84 counts of involuntary manslaughter, with CEO Bill Johnson saying, “Guilty, your honor” 84 times while a judge read the names of nearly every person who died in the Camp fire, as my colleague Julia Wick reports.)
The Colorado River begins high in the Colorado Rocky Mountains. The water begins from melting snow and rain, and is then supplemented by the Gunnison, Green, San Juan, Little Colorado, Virgin, and Gila Rivers. Before any dams were built, the Colorado River carried 380,000 million tons of silt to the Sea of Cortez.
The Colorado River is the most fought over, litigated, and legislated river in the United States. The upper Colorado passes through mountainous, less populated country.
Parker Dam, below Davis was built in 1934 to facilitate the 242 mile long Colorado River Aqueduct. This was another of Metropolitan Water District’s projects to transport water to Los Angeles. With Hoover and Parker, California could receive 5.6 million acre feet from the Colorado River.
The Grand Canyon does not only display spectacular beauty, but numerous other features such as mesas, buttes, spires, balancing rocks, natural arches and bridges, sand dunes, massive sandstone walls, and pottholed cliffs. Dry Lower Plains: These consist of the arid desert areas.
The Grand Canyon is in fact one of the World’s Seven Wonders. The Colorado Basin covers 240,000 square miles of drainage area. At certain points along the river, it turns into a raging, muddy, rapid covered mass of water.
