About Wiggins Mill Pond Dam
The primary purpose of Wiggins Mill Pond Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by George Schreppler (private). It impounds the Appoquinimink River-tr near St Andrews School.
The dam stands 17 feet tall and stretches 350 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 201 acre-feet, and collects water from a drainage area of 4 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.
