About Milner Lake Dam
Milner Lake Dam is a dam in St. Louis, Missouri. The dam is owned by Brent Milner (private). It impounds the Meramec near Eureka.
The dam stands 34 feet tall, creates a reservoir covering 5 acres, has a maximum storage capacity of 69 acre-feet, and collects water from a drainage area of 26 square miles.
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 07/18/1996. That was 29 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
At 34 feet, this dam is taller than 80% of dams nationwide.
