Twin Falls is a waterfall on the Snake River in the Snake River Canyon of south-central on border of Twin Falls and Jerome counties in Idaho, United States,[1] a few miles east of its namesake city, Twin Falls.

Water flows westward over Twin Falls and is controlled by the Twin Falls Dam, built in the 1930s and used for irrigation and hydroelectric power generation.

There were originally two parallel falls, but the dam permanently diverted the flow from the southern falls, leaving a single (north) waterfall.

[2][3] Before the dam, very high flow rates could result in a smaller third falls, to the south.
