Navigation Conditions at Gray's Landing Locks and Dam, Monongahela River; Hydraulic Model Investigation
The Monongahela River (Figure 1) is formed by the confluence of the Tygart Valley and West Fork Rivers at Fairmont, WV, and flows in a northerly direction joining with the Allegheny River at Pittsburgh, PA, to form the Ohio River. The river drains an area of 7,386 square miles and drops a total of 147 ft in its 128.7-mile length. Gray's Landing Lock and Dam is a proposed replacement structure for existing Lock and Dam 7 on the Monongahela River. The new lock and dam will be located near the mid-point of a mile-long straight reach of the river at about mile 82.2 in the vicinity of Gray's Landing, PA, and about 2.8 miles downstream of the existing Lock and Dam 7. The new lock and dam will establish an upper pool at el 778.0 that will extend about 8.6 miles upstream to Dam 8 (which has been renamed Point Marion Lock and Dam) and is in the vicinity of Point Marion, PA.
