Braddock Locks and Dam is one of nine navigation structures which provide for year-round navigation on the Monongahela River between Pittsburgh, PA and Fairmont, West Virginia. It maintains a pool for 12.6 miles upstream to Locks and Dam 3 at Elizabeth, PA .

Location
Braddock Locks and Dam is located at river mile 11.2 at the city of Braddock, PA. The lock chambers and operations buildings are situated along the right bank of the river adjacent to a major steel-making plant. Road access to the project is from 11th Street in Braddock.

History
Construction of Locks and Dam 2 at this present site was begun in 1902 and completed in 1906. After some 40 years of use, a major rehabilitation of the project was completed in 1953. This work involved reconstruction and enlargement of the lock chambers and adjustment of the length of the dam.

Braddock Locks and Dam is part of the Lower Mon Project which has modernized Braddock, is in the process of modernizing Locks and Dam 4, Charleroi, Pa., and will remove Locks and Dam 3, Elizabeth, Pa.

Locks and Dam 3 is one of nine navigation structures which provide for year-round navigation on the Monongahela River between Pittsburgh, Pa., and Fairmont, W.Va.. It maintains a pool for 23.8 miles above the mouth of the Youghiogheny River, just above Elizabeth, Pa.

Location
Locks and Dam 3 is located at river mile 23.8 at the city of Elizabeth. The lock chambers and operations buildings are situated along the right bank of the river adjacent to a main line of Pittsburgh and Lake Erie Railroad. Road access to the project is from a local road going south out of Elizabeth.

History
Construction of Locks and Dam 3 at this present site was begun in 1905 and completed in 1907. After some 70 years of use, a major rehabilitation of the project, the busiest on the Mon River, was completed in 1980. This work involved reconstruction of the lock chambers.

Project Information
Locks and Dam 3 consists of two lock chambers and a fixed crest dam. This type of dam is basically a concrete weir or wall across the river which keeps the river channel upriver of the project deep enough for navigation -- about 9 feet or more. Water which flows over this type of dam cannot be controlled locally. Consequently, it cannot provide any control over flood waters. An incidental benefit derived from the pool formed by the dam is the availability of a source of municipal and industrial water.

Locks and Dam 3 is part of the Lower Mon Project which has modernized Braddock Locks and Dam, is in the process of modernizing Locks and Dam 4, Charleroi, Pa., and will remove Locks and Dam 3, Elizabeth, Pa.

Charleroi Locks and Dam is one of nine navigation structures which provide for year-round navigation on the Monongahela River between Pittsburgh, Pa., and Fairmont, W.Va. It maintains a pool for 19.7 miles upstream to Maxwell Lock and Dam just south of Brownsville, Pa.

Location
Charleroi Locks and Dam is located at river mile 41.5 at the city of Charleroi. The lock chambers and operations buildings are situated along the right bank of the river. Road access to the project is from adjacent Pennsylvania Route 906.

Directions to Lock
Take Interstate 70 to Route 906, Exit 18. Turn right (North) onto Route 906 and proceed 1.5 miles to the lock.

History
Construction of Lock and Dam 4 at this present site was begun in 1931 and completed in 1932. After some 35 years of use, a major rehabilitation of the project was completed in 1967. This work involved reconstruction of the dam, which converted it from a fixed crest to a gated dam and raised the pool level 6 feet. Coupled with the construction of the Maxwell Locks and Dam project, the pool raise eliminated the need for old Lock and Dam 5 at Brownsville.

Project Information
Charleroi Locks and Dam consists of two lock chambers and a gated dam. This type of dam is constructed to permit increased control over the water level in the navigation pool upriver of the dam. Machinery mounted on tall concrete piers moves large chains which lift gates that are hinged into the body of the piers. As the gates are raised or lowered to control the amount of water flowing under them, the upstream pool is maintained at a relatively constant level for an authorized depth of at least 9 feet throughout its length. The dam, however, cannot be operated to control flood flows. An incidental benefit derived from the pool formed by the dam is the availability of a source of municipal and industrial water.

Grays Landing Lock and Dam is one of nine navigation structures which provide for year-round navigation on the Monongahela River between Pittsburgh, PA and Fairmont, West Virginia. Grays Landing maintains a pool for 8.8 miles upstream to Point Marion Lock and Dam

Location
Grays Landing Lock and Dam is located at river mile 82 near the community of Grays Landing, Pennsylvania. Access to the lock chamber and operations buildings is on the right descending bank of the Monongahela River off State Route 166 South.

History
Grays Landing Lock and Dam replaced Lock and Dam 7, which was located three miles upriver from the new project. Construction of the project began in 1988. The lock was completed in March 1993 and the dam in June 1995. Lock 7 was constructed between 1923 - 1926 and replaced the original timber and stone structure built just upstream of Grays Landing, PA, in the late 1800s.

Project Information
Grays Landing Lock and Dam consists of one lock chamber and a fixed-crest dam. This type of dam is basically a concrete weir or wall across the river which keeps the river channel upriver of the project deep enough for navigation -- at least 9 feet. Water which flows over this type of dam cannot be controlled locally and consequently cannot provide any control over flood waters. An incidental benefit derived from the pool formed by the dam is the availability of a source of municipal and industrial water supply.

Point Marion Lock and Dam is one of nine navigation structures which provide for year-round navigation on the Monongahela River between Pittsburgh, Pa., and Fairmont, W.Va. Point Marion maintains a pool for 11.2 miles upstream to Morgantown Lock and Dam.

Location
Point Marion Lock and Dam is located at river mile 90.8 near the community of Point Marion, Pa. The lock chamber and operations buildings are situated along the left descending bank of the river. Road access to the project is from Power Plant Road, leading south from State Route 88 at the Point Marion bridge.

History
The original Point Marion Lock and Dam, previously known as Lock and Dam 8, was built between 1923 - 1926. In 1959, the dam was changed from a fixed crest to a gated type. The Water Resources Development Act of 1986 authorized replacement of the existing lock chamber with a larger lock chamber (84 feet by 720 feet) on the landward side of the existing chamber. Using an innovative, award-winning design in constructing the chamber, the new lock was dedicated in September 1994.

Project Information
Point Marion Lock and Dam consists of one lock chamber and a gated dam. This type of dam is constructed to permit increased control over the water level in the navigation pool upstream of the dam. Machinery mounted on tall concrete piers moves large chains which lift gates that are hinged into the body of the piers. As the gates are raised or lowered to control the amount of water flowing under them, the upstream pool is maintained at a relatively constant level for an authorized depth of at least 9 feet throughout its length. The dam, however, cannot be operated to control flood flows. An incidental benefit derived from the pool formed by the dam is the availability of a source of municipal and industrial water supply.

Opekiska Lock and Dam is one of nine major structures on the Monongahela River which provides year-round navigation from Pittsburgh, Pa., to Fairmont, W.Va. Visitors are welcome at Opekiska Lock and Dam, but because of the limited hours of operation for this facility, you should check in advance with the lock by calling 304-366-4224.

History
Completing the modernization of the West Virginia portion of the Monongahela River was realized with the construction of the Opekiska Lock and Dam project between 1961 and 1964. Thus, Locks 14 and 15, the last of the 60-year-old locks and dams, were removed. The navigation channel on the Monongahela River now extends from The Point in Pittsburgh several miles into the Tygart and West Fork rivers at Fairmont.
