About Bee Tree Lake Dam
The primary purpose of Bee Tree Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by St. Louis County (local government). It impounds the Tr to Meramec River near Herculaneum.
The dam stands 18 feet tall, creates a reservoir covering 9 acres, has a maximum storage capacity of 87 acre-feet, and collects water from a drainage area of 180 square miles. Completed in 1972, 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.
