About Lake Ziske Dam
The primary purpose of Lake Ziske Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Dr. T.m. Ziske (private). It impounds the Tributary to Spring Creek near Salem.
The dam stands 24 feet tall, creates a reservoir covering 29 acres, has a maximum storage capacity of 372 acre-feet, and collects water from a drainage area of 375 square miles. Completed in 1965, 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 09/05/1978. That was 48 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.
