The U.S. Army Corps of Engineers Philadelphia District is managing a project to dredge portions of the Schuylkill River above the Fairmount Dam in Philadelphia, PA. The contract calls for dredging approximately 60,000 cubic yards of sediment from the river. The dredged material will be pumped through pipeline over the Fairmount Dam and onto barges located south of the Route 676 Bridge. The barges will then travel south on the river and will dispose of the dredged material by pumping it to the Fort Mifflin Confined Disposal Area.

Background: The U.S. Army Corps of Engineers Philadelphia District is managing a project to dredge portions of the Schuylkill River above the Fairmount Dam in Philadelphia, PA. The project is funded through a combination of the following sources: City of Philadelphia, State, local universities, William Penn Foundation, Schuylkill Navy and the rowing and paddling communities.

Work Details: The Army Corps awarded a contract to Atlantic Subsea, Inc. of Bridgeport, NJ to dredge portions of the river in the Boathouse Row area; the Adaptive Rowing lagoon; and the Race Course near the Strawberry Mansion Bridge. In March 2020, Atlantic Subsea began mobilizing equipment and making preparations to begin dredging (currently expected to start in early June).

The contract calls for dredging approximately 60,000 cubic yards of sediment from the river. Atlantic Subsea, Inc. will be using a Mudcat 115D hydraulic dredge to complete the work. The dredge uses a system of cables, anchors, and winches to move around the dredging area. The dredged material will be pumped through pipeline over the Fairmount Dam and onto barges located south of the Route 676 Bridge. The barges will then travel south on the river and will dispose of the dredged material by pumping it to the Fort Mifflin Confined Disposal Area (site is owned and operated by the U.S. Army Corps of Engineers). The contractor staging area is located near the PA Center for Adaptive Sports Rowing and the Temple University Boathouse.
