The Ohio Department of Natural Resources (ODNR) is overseeing the $24 million undertaking to replace the historic McConnelsville Dam.
In an effort to preserve the historic Muskingum Parkway lock and dam system and allow for continued recreational navigation, crews in Morgan County, Ohio, are replacing the historic McConnelsville Dam. The Ohio Department of Natural Resources (ODNR) is overseeing the $24 million undertaking. “There have been several repairs to the

sheet pile structure, including interim improvements to stabilize the right abutment,” said James Hilovsky, a team lead of ODNR’s division of engineering. “Overall, the existing cellular sheet pile dam is in poor condition beyond its serviceable lifespan, and in need of replacement.” Site work and preparation began earlier this year, with water work starting in June. The project is expected to be completed in
three summer construction seasons. “We are currently in the first phase, which includes construction of the left and right abutments and a portion of the new dam starting from the left abutment. The remaining sections of the dam will be constructed in the second season, and the existing dam removal and other site work completed in the third season.” The new structure will be approximately
580 ft. downstream of the existing dam. “The original dam was constructed in 1841 and was similar in nature to many of the other dams along the river which are rock-filled timber crib structures, later capped with concrete. The original McConnelsville Dam failed in the late 1940s and was replaced with the sheet pile structure currently in service today.” see DAM page 6
