New Kent County’s Crump’s Mill and Millpond, typical of country gristmills of the Tidewater region, was improved and modernized over time. It is unusual that much of the mill’s machinery survived. The millpond is considerably larger and older than most and has a watershed that has not changed since the mid to late 19th century. No modern cultural practices have influenced or altered its flow since the dam was built sometime before 1818. The succession of plant and animal life around the Crump’s Mill and Millpond is unique because of the natural undisturbed environment in which this living ecosystem exists.
