About Limpp, Earl Lake Dam
The primary purpose of Limpp, Earl Lake Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Earl Limpp (private). It impounds the Tr-davis Creek near Mound City.
The dam stands 26 feet tall, creates a reservoir covering 14 acres, has a maximum storage capacity of 195 acre-feet, and collects water from a drainage area of 733 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. The most recent inspection on record was 05/16/1979. That was 46 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
