Anchor Dam was built in the 1950s on upper Owl Creek in Wyoming’s Bighorn Basin. The bedrock under the reservoir site is porous, and the reservoir has never held much water. The U.S. Bureau of Reclamation more than doubled its initial costs with subsequent mitigation efforts, which proved unsuccessful. The dam stands today high above a small pool of water.

Guernsey Dam on the North Platte River lies between historic Fort Laramie and Laramie peak and just a few miles from some deep, sandstone ruts on the historic Oregon Trail. The dam was completed in 1927, for hydropower and flood control. In 1934, crews from the Civilian Conservation Corps located camps near the reservoir. With design help from the National Park Service, they built the handsome stone-and-timber shelters and buildings at Guernsey State Park, in what became a showplace of state park design.
Construction of Buffalo Bill Dam, completed in 1910 six miles west of Cody, Wyoming, was the key that opened about 90,000 acres in northwestern Wyoming to irrigated farming. Its construction was slowed by engineering difficulties and labor strife, but when it was finished stood as an engineering marvel, one of the first concrete arch dams built in the United States and the tallest dam in the world at the time.
Before Glendo Dam could be built on the North Platte River in Platte County, Wyoming, complicated water-rights disputes had to be settled among Wyoming, Nebraska and Colorado and the settlement approved by the U.S. Supreme Court. The process took more than a decade, and shows the difficulties of allocating water in the arid West. The earthfill dam, nearly 2,100 feet long and 190 feet high, was completed in the fall of 1957. It stores water for irrigation and recreation, controls floods, reduces sedimentation in the Guernsey reservoir downstream and produces hydropower.
In 1869, explorer John Wesley Powell named the red-walled canyon on the Green River in Wyoming Territory “Flaming Gorge.” The Flaming Gorge Dam, completed in 1964, helps regulate water flows and its power plant generates electricity. The dam is located in Utah, but the reservoir stretches north into Wyoming near the town of Green River. In 1968, the U.S. Congress created the Flaming Gorge National Recreation Area, which is located in the states of Utah and Wyoming and draws visitors from around the world.
Tracing its roots to a work camp for men digging irrigation ditches early in the 20th century, Powell, Wyoming, in northern Park County, remains an agricultural hub. Its economy has been boosted over the last century, however, by nearby coal mines and oil wells, and by public schools, a hospital and a community college, the last three of which are now the town’s largest employers. In 1994, Powell was one of 10 municipalities named an All-America City by the National Civic League.
