Bureau of Reclamation in Wyoming

The Pacific Northwest Region's Minidoka Project extends into the upper Snake River drainage of western Wyoming. Two reservoirs provide valuable storage and river regulation for downstream users—Jackson Lake Dam and Palisades Dam in Idaho.

Pacific Northwest Region activities in Wyoming are limited to the operation of Jackson Lake Dam and Grassy Lake Dam, located in Grand Teton National Park. This area is administered by the Upper Snake Field Office.

Pioneer farmers and ranchers in Wyoming relied heavily on irrigation practices to secure water necessary to sustain their livelihoods in a state with erratic and low annual precipitation. Following the Civil War, Wyoming's expanding livestock industry fueled irrigation development throughout the state, as additional farms were needed to grow forage crops.

Without irrigation, many farms could not survive. As the rapid expansion of ranching and farming continued, it became apparent that Wyoming needed dependable water supplies. Early projects developed by the Reclamation Service supplied irrigation water to Wyoming and provided other benefits such as water for hydropower, municipal and industrial uses, recreation, and fish and wildlife.

Jackson Lake, at the headwaters of the Snake River, stores water used for irrigation in the fertile Snake River Valley in Idaho. Jackson Lake Dam was completed in 1916, many years before Grand Teton National Park was established.

With the exception of two storage reservoirs, Jackson Lake and Grassy Lake, the remainder of Reclamation projects in Wyoming are managed by the Great Plains Region.
