About Windsor Farrington Park Lake Dam

The primary purpose of Windsor Farrington Park Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by City Of Windsor (local government). It impounds the Tr-elm Branch near Windsor.

The dam stands 26 feet tall, creates a reservoir covering 15 acres, has a maximum storage capacity of 209 acre-feet, and collects water from a drainage area of 752 square miles. Completed in 1902, the structure is over a century 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 07/16/1980. That was 45 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

If you live or work downstream of this dam, consider taking these steps: learn your local evacuation routes, check whether your county emergency management office has a dam failure inundation map, and sign up for local emergency alerts. The Missouri dam safety program can provide more specific information about emergency planning for this structure.
