Nestled four miles east of Rupert, Acequia boasts only a few more residents than its neighbor to the east, Minidoka. About 110 people call Acequia home year-round, said the city's recently retired clerk, Eldon Stephenson. Acequia was charted in August 1907. Prior to that time, the settlement was called Sherrer, after one of its first settlers. It began to grow after the Minidoka Dam was completed and water began to run through the canals to surrounding farmland.

Mayor: Larry Wall
