Minidoka County is located in the fertile Snake River Plain of Southern Idaho approximately 160 miles east of Boise, 160 miles northwest of Salt Lake City, Utah and 90 miles west of Pocatello. The county contains approximately 480,000 acres, of which 42% is in production agriculture. The county has a unique topography and elevation. Its southern portion, which runs along the Snake River, was originally part of the riverbed. Its northern portion runs over a somewhat higher table and is called the North side project. Its extreme northern and eastern boundaries consist of lava flows with large and small areas of arable land. Although the surface structure is varied, there is only 180 feet difference in elevation from the lowest point at the southwest corner, 4180 feet and its highest point in the northeast corner, 4360 feet.
