The Colorado river - basic facts

It flows through southwest United States and northwestern Mexico.

It is 2334 km (1450 miles long), the longest river west of the Rocky Mountains.

Its source is west of the Rocky Mountains which is the watershed in northern Colorado, and, for the first 1600km (1000miles) of its course, passes through a series of deep gorges and canyons that were created by the eroding force of its current.

The river flows in a generally southwestern direction across Colorado into south eastern Utah, where it is joined by its chief tributary, The Green River. After crossing the northern portion of Arizona, the Colorado flows west for 436 km (271 miles) through the majestic Grand Canyon. Then it flows in a generally southerly direction and forms the boundary between Arizona and the states on Nevada and California. Near Yuma, Arizona, the river crosses the international border into Mexico and flows for about 145km (90 miles) to its mouth on the Gulf of California.

The River Colorado drains parts of 7 states, a total area in Colorado, Wyoming, Nevada, Utah, Arizona, New Mexico and California, of about 626,800sq km.

What controls / how have people controlled the flow ?

20 dams have been built, many of them by the U.S. Bureau of Reclamation, along the River and the tributaries.

The Hoover Dam, which holds back at the Black Canyon to form the reservoir Lake Mead,

one of the largest artificial lakes in the world.

The Glen Canyon Dam in north-central Arizona, south of the Utah border is the third highest dam in the U.S.

Why is the river controlled ?
