Loch Lomond Dam

About Loch Lomond Dam

The primary purpose of Loch Lomond Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Bella Vista Village Property Owners Association (private). It impounds the Sugar Creek-tr near Bella Vista Village.

The dam stands 80 feet tall and stretches 1,770 feet across, creates a reservoir covering 477 acres, has a maximum storage capacity of 23,099 acre-feet, and collects water from a drainage area of 13 square miles. Completed in 1981, the structure is 45 years old.

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. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 01/14/2026.

At 80 feet, this dam is taller than 97% of all dams in the United States.
