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 Crystal Lakes Developmnt (private). It impounds the Tr to Fishing River near Excelsior Springs.

The dam stands 30 feet tall, creates a reservoir covering 7 acres, has a maximum storage capacity of 112 acre-feet, and collects water from a drainage area of 430 square miles. Completed in 1968, 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.

If you live or work downstream of this dam, consider taking these steps: learn your local evacuation routes, check whether your county emergency management office has a dam failure inundation map, and sign up for local emergency alerts.
