About Univ Mo Exp Farm Dam- Mononame 207
The primary purpose of Univ Mo Exp Farm Dam- Mononame 207 is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by Mo Dept Of Conservation (state). It impounds the East Branch Of Crooked Creek near Weldon Spring.
The dam stands 29 feet tall, creates a reservoir covering 50 acres, has a maximum storage capacity of 776 acre-feet, and collects water from a drainage area of 300 square miles. Completed in 1958, 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 09/04/1979. That was 46 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
