National Dam Safety Program. Cherrystone Number 2A (Inventory Number VA 14303), Pittsylvania County, Virginia. Phase I Inspection Report
Cherrystone Dam No. 2A is a zoned earth-fill structure about 400 ft long and 68 ft high. The principal spillway consists of a 36 inch prestressed cylinder concrete pipe, which extends through the structure. Water is discharged into the principal spillway through a reinforced concrete riser and is expelled into a riprap plunge pool. The emergency spillway is a 200 ft wide vegetated earth channel. The dam is located on Roaring Fork Creek near its junction with Cherrystone Creek about 2.5 miles northwest of Chatham, Virginia. The dam was constructed for flood control and recreational purposes. The dam is of 'intermediate' size and has been assigned a 'significant' hazard classification. The appropriate spillway design flood is the 1/2 Probable Maximum Flood (1/2 PMF). The emergency spillway will pass 70 percent of the PMF prior to overtopping. Based on criteria established by the Department of the Army, Office of the Chief of Engineers (OCE), the spillway is rated adequate.
