About Sugar Loaf Lake Dam
The primary purpose of Sugar Loaf Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Arkansas Game And Fish Commission (state). It impounds the Johnson Branch near Montreal.

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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 07/28/2025.
At 60 feet, this dam is taller than 95% of all dams in the United States.
