Minidoka Powerplant and Dam is a combined diversion, storage, and power structure located just south of Minidoka, Idaho. Minidoka Dam was originally designed and constructed without a powerplant and was completed in 1907. The powerplant (and three pumping plants) was added later (1909-1910) to allow water to be delivered to lands which could not be fed by gravity irrigation. Lake Walcott and Minidoka Dam are on the Snake River. Columbia Basin Teletype (CBTT) = MIN.
