About Narrows Dam

The primary purpose of Narrows Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Usace - Vicksburg District (federal). It impounds the Little Missouri River near Murfreesboro.

The dam stands 196 feet tall and stretches 940 feet across, creates a reservoir covering 7,200 acres, has a maximum storage capacity of 600,600 acre-feet, and collects water from a drainage area of 237 square miles. Completed in 1950, the structure is well-established, with more than 75 years of service.

This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. An emergency action plan is in place for this dam. The most recent inspection on record was 07/09/2020.

At 196 feet, this dam is taller than 99% of all dams in the United States.
