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.

Along with a local sponsor, Natural Resources Conservation Service (NRCS) funding was approved for rehabbing this structure through a national dam rehab pilot project. Construction began in June, 2004 and continued through the end of August, 2004. NRCS provided the design and plans for construction, as well as technical advice and inspection during construction. This presentation will cover all aspects of the rehabilitation project, including details of the site, construction, and the finished product. Discussion will also include other issues faced during this project, such as easement and land rights issues, public relations and dealing with the local land owners, and establishing a successful working relationship between cooperating agencies.
