National Dam Safety Program. Coburn Dam (Inventory Number VA 03340), York River Basin, Carolina County, Virginia. Phase I Inspection Report
Coburn Dam is an earthfill embankment 17.0 feet high and approximately 350 feet long. The dam is located in Caroline County, approximately 1.5 miles northwest or Ruther Glen, Virginia. The dam is used for recreation. Coburn Dam is a 'small' size - 'significant' hazard structure as defined by the Recommended Guidelines for Safety Inspection of Dams. The dam and appurtenant structures were in fair condition at the time of inspection. Deficiencies found during the field inspection and office analyses will require remedial treatment. A stability check of the dam is not required. The principal spillway is a 54-inch diameter bituminous coated corrugated metal pipe (BCCMP) acting as a fixed crest riser connected to a 30-inch BCCMP that passes through the embankment. The emergency spillway is a vegetated earth trapezoidal channel located on the left abutment. An emergency drain has been provided for dewatering the reservoir. The control for the gate valve is located 50 feet upstream of the principal spillway. This gate controls the entrance to a BCCMP that drains into the bottom of the principal spillway riser.
