The Colorado River is about 1,400 miles long and flows through seven U.S. states and into Mexico. The Upper Colorado River Basin supplies approximately 90 percent of the water for the entire basin. It originates as rain and snow in the Rocky and Wasatch mountains. Credit USGS.

A raft floats past silt walls left on the Colorado River and revealed by dropping levels in Lake Powell, in October 2016. A “risk study” being undertaken by west slope water interests wants to know who might have to someday divert less water to keep Lake Powell operational. Photo credit Brent Gardner-Smith.

Nearly the full length of Lake Powell on the Colorado River in southern Utah and northern Arizona is visible in this photograph shot by an astronaut aboard the International Space Station, on Sept. 6, 2016.

The snow-capped mountains of Colorado and Utah contain trillions of gallons of water stored in the form of snow. Meltwater from this snow will eventually flow into the Colorado River, delivering much needed water to seven Western states and 33 million people. Accurately predicting water from snowmelt is critical to the region, and Earth-observing satellites can help. Credits: iStock

This graphic shows the transmountain diversions in Colorado. The Bousted Tunnel, at 53,871 AF, the Twin Lakes Tunnel, at 46,930 AF, and the Busk-Ivanhoe Tunnel, at 4,123 AF, have taken (in this data set) a combined average of 105,024 AF a year from the top of the Roaring Fork and Fryingpan rivers headwaters.
How much water reaches the Westwater stretch of the Colorado River, and then Lake Powell, is taking on increasing importance to Colorado water officials. A new study is underway to look at much more water is available to develop on the Western Slope, and it’s caught the attention of east slope water officials.

The Colorado River supplies water to Lake Mead, the largest man-made reservoir in terms of capacity in the United States. New research from The University of Texas at Austin has found natural variability, not humans, have the most impact on water stored in the river and the sources that feed it. U.S. Geological Survey
