The Teton Basin Project on the upper Teton River in eastern Idaho comprised the Teton Dam and reservoir. The dam failed on June 6, 1976 as the 288,250-acre-foot (0.35555 km3) reservoir was being filled, leading to extensive flooding in the Minidoka project area.[7] The Ririe Project in the Willow Creek drainage stores up to 100,500 acre feet (0.1240 km3) of drainage from the Caribou Range.[8]
