About Lake Windsor Dam

The primary purpose of Lake Windsor 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 Tanyard Creek near Bella Vista Village.

The dam stands 95 feet tall and stretches 1,228 feet across, creates a reservoir covering 220 acres, has a maximum storage capacity of 9,400 acre-feet, and collects water from a drainage area of 11 square miles. Completed in 1974, 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 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 01/20/2026.

At 95 feet, this dam is taller than 98% of all dams in the United States.
