ORDWAY, S.D. (AP) — A set of dams that were built in the 1930s along the Elm River in northeastern South Dakota might be evaluated in 2016.

The Aberdeen American News reports that Aberdeen officials are considering whether to request proposals to have the three dams inspected to determine the work they needed.

The structures are part of a system that provides drinking water to Aberdeen residents.

Water Superintendent Janel Ellingson says officials know the dams need maintenance, but an inspection is needed to identify and prioritize the repairs.

The three low-level dams are set along the Elm River. The first is near Ordway and the last by Westport.

Ellingson says the dams hold water to an average depth of about 10 feet, with a maximum of 20 feet.
