Dunham Lake Dam

About Dunham Lake Dam

The primary purpose of Dunham Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by City Of Edmonton (local government). It impounds the Little Barren River near Edmonton.

The dam stands 25 feet tall and stretches 560 feet across, creates a reservoir covering 18 acres, has a maximum storage capacity of 240 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1955, the structure is well into its service life at over 50 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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. The most recent inspection on record was 08/19/2025.
