Buckhorn Reservoir is a reservoir in Wilson County, North Carolina created by the Buckhorn Dam. The reservoir is the primary water supply for the city of Wilson, North Carolina. The original Buckhorn Dam was built in 1974, 1,000 feet (300 m) upstream from the current dam. The reservoir at that time only had the ability to contain 800 million US gallons (3,000,000 m³) of water. In 1999, a new dam was constructed downstream from the older dam creating a reservoir with a much larger capacity.
