About Nine Eagles Park Lake Dam

The primary purpose of Nine Eagles Park Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Iowa Department Of Natural Resources (state). It impounds the Tr-thompson River near Cainsville, Mo.

The dam stands 53 feet tall and stretches 1,000 feet across, creates a reservoir covering 59 acres, has a maximum storage capacity of 1,560 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1930, the structure is well-established, with more than 75 years of service.

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 05/09/2022.
