Now, the flows over the falls can be viewed seasonally based on snowfall, irrigation needs and hydroelectric demands.
Irrigation and hydroelectric power stations built on the falls were the primary contributors to early economic development in southern Idaho.
The flow over the falls ranges from over 20,000 cubic feet per second (570 m It is the tallest of several cataracts along this stretch of the Snake River, being located about 2 miles (3.2 km) downstream from Twin Falls and 1.5 miles (2.4 km) upstream from Pillar Falls.
Formed by catastrophic outburst flooding during the Pleistocene ice age about 14,000 years ago, Shoshone Falls marks the historical upper limit of fish migration (including salmon) in the Snake River, and was an important fishing and trading place for Native Americans.
The falls were documented by Europeans as early as the 1840s; despite the isolated location, it became a tourist attraction starting in the 1860s.
The Snake River above Shoshone Falls shares only 35 percent of its fish species with those of the lower Snake River below the falls.
Fourteen fish species found in the upper Snake are also found in the Bonneville freshwater ecoregion (which covers the Great Basin portion of Utah), but not the lower Snake or Columbia rivers.
