Structure R-23 is one of many aging watershed dams in the Upper Hocking Watershed of
Fairfield County, Ohio. Like several others, R-23 was in need of rehabilitation to address growing
problems. Deterioration of the principal spillway pipe and riser threatened possible failure of the
structure. The dam was reclassified as a medium hazard structure, which warranted work to meet
current safety and performance standards. In addition, the private road across the top of the dam
provides the only access to several residences. The immediate surrounding area of the structure
has undergone significant development since original construction in 1960. Considering these
reasons, it was felt that rehabilitation was necessary.
