About Blackberry Hay Farm Dam
The primary purpose of Blackberry Hay Farm Dam is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by William F Lethone (private). It impounds the Pond Creek near Asbury.
The dam stands 20 feet tall, creates a reservoir covering 160 acres, has a maximum storage capacity of 1,712 acre-feet, and collects water from a drainage area of 1,680 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 06/20/1979. That was 46 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
