Minidoka County was created by the Idaho Legislature on January 28, 1913 by a partition of Lincoln County. The name Minidoka is of Dakota Sioux origin meaning "a fountain or spring of water." [2] Minidoka was first used in 1883 as a name for a Union Pacific, Oregon Short Line, spur in the middle of the Snake River Plain. The spur later became the site of a watering station along the line. The village of Minidoka grew up next to the station. Minidoka was then given to a reclamation project under then President, Theodore Roosevelt.
