About Twin Falls County
Twin Falls County lies on the south side of the Snake River in central Idaho, including everything south of the river to the Nevada border. The Snake River passes through a deep and dramatic gorge along the north side of the county, being 500 feet deep in places. Numerous waterfalls can be found along the gorge, including the famous Shoshone Falls. The city, Twin Falls, is the county seat and only large city in the county, home to more than half of the county's 77,230 residents (2010 census).
For several miles south of the river the land is flat, being part of the Snake River Plain, a fertile agricultural region occupying much of southern Idaho. This area slopes upward from about 3,600 feet at the edge of the gorge, gaining elevation southward, and giving way to hills and to some low-relief mountains along the Nevada border. Several rural towns dot this farming area, including Buhl, Kimberly, Filer and Hansen.
U.S. Highway 30 passes east-west through Twin Falls County, and U.S. Highway 93 heads north and south. They meet at Twin Falls. Highway 30 continues eastward into Cassia County, coming to Burley. Heading west, it makes a turn to the north and crosses the Snake River into Gooding County, arriving at Hagerman. Interstate 84 passes by Twin Falls on the north side of the river, and Highway 93 accesses by a dramatic bridge 500 feet above the Snake River.
The settlement of Twin Falls County began mostly in 1905 when the Milner Dam was built and irrigation water became available to farm the extensive farmland. Twin Falls, the city, was founded the year before that, 1904. At that time, it was part of Cassia County, but was divided off on February 21, 1907.
