The engineering needs of the Susquehanna Canal , were modest in comparison to many contemporary projects , and construction was timed after other more difficult projects in the system were well under way .. The Susquehanna Division Canal employed 12 locks overcoming a total of just 86 ft in its 41 mis length It was begun in 1827 and was finished in 1831 in time to connect to traffic between the Union Canal and the Allegheny Portage Railroad , which lifted wheeled canal barges up on of the gaps of the Allegheny and over the Allegheny Plateau into the Allegheny-Ohio valleys ..

Boats had to cross from one side of the Susquehanna River to the other between either the Susquehanna Division or the Juniata Division on the west side and the Eastern Division on the east side .. They solved the problem by building a dam 1998 ft long and 8.5 ft high between the lower end of Duncan 's Island and the east bank of the Susquehanna ..
