Salmon Falls Dam is a dam constructed across Salmon Falls Creek in Twin Falls County, Idaho in the United States. Located about 28 miles (45 km) southwest of Twin Falls, the masonry arch-gravity dam is 217 feet (66 m) high and 450 feet (140 m) long, impounding up to 230,650 acre feet (0.28450 km3) of water in Salmon Falls Creek Reservoir. When full, the reservoir extends for 17 miles (27 km) upstream, encompassing 3,400 acres (1,400 ha). The dam and reservoir control runoff from a drainage basin of 1,610 sq mi (4,200 km2).
The dam was built in 1910 to provide irrigation water storage, and is owned and operated by the Salmon River Canal Company. A secondary purpose is flood control: the dam has never spilled floodwaters with the exception of the heavy snowmelt of 1984. Salmon Falls Creek Reservoir is also a popular recreational lake, and is considered one of the best fisheries in southern Idaho.
