What is now Minidoka County was first surveyed in 1890 for a plausible location to construct a dam. On June 7, 1902, President Theodore Roosevelt signed the Reclamation Act allowing construction of the dam. In 1904, the Reclamation Service reserved three-one square mile town sites for Burley, Rupert, and Riverton (now known as Heyburn).
History
The area's first permanent residents arrived in 1868 settling in Albion. Many Mormon pioneers, under the direction of Utah Territory Governor Brigham Young, arrived in the Oakley Valley a short time later. Cassia County was later founded on February 20, 1879 with Albion as the county seat.
