diga del lago di Grassy

Italy

Grassy Lake Dam is a small dam operated by the U.S. Bureau of Reclamation in Teton County, Wyoming, immediately to the south of Yellowstone National Park. The dam lies in a corridor of Caribou-Targhee National Forest that runs between Yellowstone and Grand Teton National Parks. The dam structure and

outlets are within a few hundred feet of the south boundary of Yellowstone. The zoned earthfill dam was built between 1937 and 1939 as part of the Minidoka Project, which provides water to irrigate farmland in Idaho's Snake River Plain. The dam provides only water storage, impounding 15,200 acre-feet (0.0187 km3). Given the small catchment area of Grassy Creek, inflow is augmented by a 0.7-mile (1.1 km) ditch that moves water from Cascade Creek into the reservoir.
