Salmon Falls Dam is a dam constructed across Salmon Falls Creek in Twin Falls County, Idaho in the United States. Located about 25 miles (40 km) south of Buhl, 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.[1] 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).[1]

The dam was built in 1910 to provide irrigation water storage, and is owned and operated by the Salmon River Canal Company.[2] A secondary purpose is flood control: the dam has never spilled floodwaters with the exception of the heavy snowmelt of 1984.[3] Salmon Falls Creek Reservoir is also a popular recreational lake, and is considered one of the best fisheries in southern Idaho.[4]
