irrigation

Frank Mondell’s popularity and political wit propelled him to represent Wyoming on the national stage for 13 terms in the U.S. House of Representatives. Yet his legislation and political maneuvering concerning irrigation, dry farming and tribal land appropriation left a murky legacy. Read more about his life in politics.

The federal government finally entered the irrigation business in 1902, after it became clear that large infusions of public funds were needed to build projects big enough to be effective in the arid West. The eventual result was a dozen dams across Wyoming, but crop agriculture here remains scarce. 

The great Wild West showman, Buffalo Bill, failed as a capitalist leading large irrigation projects in northern Wyoming but succeeded in founding the state’s tourist industry and his namesake town, Cody—where the tourist dollar still sustains life.

The basin of the North Platte River takes up the southeastern quarter of Wyoming, plus a finger of land along the tributary Sweetwater River in the center of the state. The courses of the North Platte and Sweetwater determined early fur-trade and emigrant routes. Since that time, the basin’s water and other resources have continued to draw industry, stock raising, dams and irrigation—and people.

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.

One of Wyoming’s early large-scale irrigation projects dates to the 1880s in what’s now Platte County, Wyoming and the county, organized in early 1913, still is perhaps best known for its reservoirs and recreation areas. The Oregon Trail ruts and Register Cliff near Guernsey serve as reminders of the pioneer heritage of the area and a coal-fired power plant near Wheatland provides jobs and economic stability.

When completed in June 1909 on the North Platte River, 47 miles southwest of Casper, the granite Pathfinder Dam was a triumph of early 20th century design. It was one of the earliest federal Reclamation Service dams in the West, and convinced agency officials of their ability “to do great things.”

Elwood Mead was only 30 in 1888 when Territorial Gov. Thomas Moonlight hired him to bring order to Wyoming’s water law. As territorial engineer Mead did just that, and his ideas were written into the state constitution adopted in 1890. Mead spent only 11 years in Wyoming, but all his life carried with him what he learned in the state.

Seminoe and Kortes dams, both located in a remote stretch of northern Carbon County, Wyo., were constructed in the 1930s and 1940s primarily for the production of hydropower. While power plants at both dams still generate electricity, the area is frequented by tourists, especially fishermen who travel to the renowned Miracle Mile, just downstream from Kortes Dam, to catch trout.

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.
