The other principal goal of Glen Canyon Dam is hydroelectricity generation. It is the second-biggest producer of hydroelectric power in the Southwestern United States, after Hoover Dam. Revenues derived from power sales was integral in paying off the bonds used to build the dam and has also been used to fund other Bureau of Reclamation projects, including environmental restoration programs in the Grand Canyon and elsewhere along the Colorado River."

The ruins of St. Thomas, which became visible after the water level in Lake Mead lowered, are protected by the National Park Service as a historic site. The cemetery was relocated to Overton, Nevada where there is a St. Thomas interpretive center with a staff archaeologist doing on-going research into the history and settlement of the Muddy River. The novel Lords of St. Thomas (GWP, 2018) by Jackson Ellis tells the"

The dam is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about southeast of Las Vegas, Nevada. The dam's generators provide power for public and private utilities in Nevada, Arizona, and California. Hoover Dam is a major tourist attraction; nearly a million people tour the dam each year. The heavily traveled U.S. Route 93 (US 93) ran along the dam's crest until October 2010, when"
"until the mid-19th century, long stretches of the Colorado and Green rivers between Wyoming and Nevada remained largely unexplored due to their remote location and dangers of navigation. Because of the dramatic drop in elevation of the two rivers, there were rumors of huge waterfalls and violent rapids, and Native American tales strengthened their credibility. In 1869, one-armed Civil War veteran John Wesley Powell led an expedition from Green River Station in Wyoming, aiming to run the two rivers all the way down to St. Thomas, Nevada, near present-day Hoover Dam. Powell and nine men – none of whom had"

Construction began during 1953 due to the increased water demand of post-war Columbus. The project was completed and dedicated in 1955 and the dam officially opened in 1958. It was named for two brothers, Charles P. Hoover and Clarence B. Hoover, to honor their careers with the City of"

"the ""Law of the River"". The U.S. federal government was the main driving force behind the construction of dams and aqueducts, although many state and local water agencies were also involved. Most of the major dams were built between 1910 and 1970; the system keystone, Hoover Dam, was completed in 1935. The Colorado is now considered among the most controlled and litigated rivers in the world, with every drop of its water fully allocated. The environmental movement in the American Southwest has opposed the damming and diversion of the Colorado River system because of detrimental effects on the ecology and"
"the river might change course and empty into the Salton Sea. The Board cautioned: ""To avoid such possibilities, the proposed dam should be constructed on conservative if not ultra-conservative lines."" On December 21, 1928, President Coolidge signed the bill authorizing the dam. The Boulder Canyon Project Act appropriated $165 million for the Hoover Dam along with the downstream Imperial Dam and All-American Canal, a replacement for Beatty's canal entirely on the U.S. side of the border. It also permitted the compact to go into effect when at least six of the seven states approved it. This occurred on March 6,"

The Hoover Dam Bypass project was completed within budget at a cost of $240 million; the bridge portion cost $114 million.

After the crash, Hoover attempted to put in place many efforts to restore the economy, especially the fast-sinking agricultural sector. None worked. Hoover believed in stimulus spending and encouraged state and local governments, as well as the federal government, to spend heavily on public buildings, roads, bridges—and, most famously, the Hoover Dam on the Colorado River. But with tax revenues falling fast, the states and localities plunged into their own fiscal crises. Republicans, following their traditional mass"

The roadway is above the river. The bypass replaced the old section of U.S. 93 that approached and crossed directly over Hoover Dam,"
"Hoover Dam in the 1930s marked the beginning of the modern era for the Colorado River Delta. For six years, as Lake Mead filled behind the dam, virtually no freshwater reached the delta. Even spring flooding was captured. This ecologically devastating event was repeated from 1963 to 1981 as Lake Powell filled behind the Glen Canyon Dam. With these reservoirs now filled, the dams are used to regulate flow so that water can be reliably apportioned among the users of the Colorado River Compact, and its use maximized. Most flood flows can be contained, regulated, and added to the river's"

Construction of the Hoover Dam in the 1930s and the Glen Canyon Dam in the 1960s changed the character of the Colorado River.

By the 1950s, due to rapid population growth in the seven U.S. and two Mexican states comprising the Colorado River Basin, the Bureau of Reclamation deemed the construction of additional reservoirs necessary. However, the USBR faced opposition when it proposed the Echo Park Dam in Utah's Dinosaur National Monument, which the nascent environmental movement saw as a legal threat to the status of protected lands.
