Newton Dam, located in Adair County, Iowa, was completed in 1959 by the USDA NRCS and serves multiple purposes including fire protection and stock or small fish pond storage. This earth dam stands at 20 feet high and spans 430 feet in length, with a storage capacity of 68 acre-feet. Situated on the TR-NORTH RIVER, Newton Dam is owned and regulated by a private entity but falls under the jurisdiction of the Iowa DNR for permitting, inspection, and enforcement.

Despite its low hazard potential, Newton Dam is classified as having a moderate risk, indicating a need for ongoing risk assessment and management measures. The dam's condition is currently not rated, with its last inspection dating back to 1965. While it lacks an Emergency Action Plan (EAP) and inundation maps, the dam meets regulatory guidelines and is regularly inspected for safety. This vital water resource structure plays a critical role in the local environment and economy, providing essential water storage and flood protection for the surrounding area.
