About Timber Lake Dam
The primary purpose of Timber Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Birchwood Lake Colony Club (private). It impounds the Haynes Creek-tr near Oakwood Lakes.
The dam stands 19 feet tall and stretches 300 feet across, creates a reservoir covering 24 acres, has a storage capacity of 90 acre-feet, and collects water from a drainage area of 9 square miles. Completed in 1955, the structure is well into its service life at over 50 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.
