Little River Watershed Site 65

About Little River Watershed Site 65

The primary purpose of Little River Watershed Site 65 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 Decatur County Swcd (local government). It impounds the West Little River near State Of Missouri.

The dam stands 45 feet tall and stretches 1,470 feet across, creates a reservoir covering 144 acres, has a maximum storage capacity of 6,700 acre-feet, and collects water from a drainage area of 9 square miles. Completed in 1987, the structure is 39 years old.

This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. The most recent inspection on record was 05/28/2024.

At 45 feet, this dam is taller than 91% of dams nationwide.
