Monongahe1a Dam 2 Spillway, Monongahela River, Pennsylvania
Monongahela Dam 2, located 11.2 miles upstream of the confluence of the Ohio, Allegheny, and Monongahela Rivers, in North Braddock, PA, maintains the l2.6-mile-long navigation pool between the Dam 2 and Dam 3 locks and dams. The U.S. Army Engineer District, Pittsburgh, developed a 'two-for-three' plan for renovating locks and dams on the lower Monongahela River that would save the cost of having to reconstruct Lock and Dam (LD) 3 and reduce transportation costs by eliminating bottlenecks caused by the small locks at LD's 3 and 4 and by reducing one lockage cycle. The plan calls for building a new gated dam at the current LD 2, eliminating LD 3, and replacing the locks at LD 4 with new, larger locks. The spillway sectional model was conducted to investigate the hydraulic performance to be expected with the low sills and water quality sill under long-range operating conditions for controlled and uncontrolled flows. The model study provided the data necessary to evaluate and develop a satisfactory means of regulating the structure to achieve the desired flow objectives without creating adverse hydraulic conditions.
