About Elam Lake Dam
The primary purpose of Elam Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by William J Elam (private). It impounds the Tr-mountain Creek near Eldridge.
The dam stands 30 feet tall, creates a reservoir covering 9 acres, has a maximum storage capacity of 144 acre-feet, and collects water from a drainage area of 625 square miles. Completed in 1971, 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.
