Diepholz Pond Dam

About Diepholz Pond Dam

The primary purpose of Diepholz Pond Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Morry Diepholz (private). It impounds the Trib Embarass River near Greenup.

The dam stands 20 feet tall, and has a maximum storage capacity of 65 acre-feet. Completed in 1960, 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 08/28/2024.
