About Johnmeyer Lake Dam
The primary purpose of Johnmeyer Lake Dam is fire protection, stock, or small fish pond. The dam maintains a small impoundment used for fire suppression, livestock watering, or as a fish pond. The dam is owned by J H Johnmeyer (private). It impounds the Tr-doe Creek near New Franklin.
The dam stands 32 feet tall, creates a reservoir covering 6 acres, has a maximum storage capacity of 103 acre-feet, and collects water from a drainage area of 32 square miles. Completed in 1952, 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.
At 32 feet, this dam is taller than 76% of dams nationwide.
