The West Branch Division of the Pennsylvania Canal ran 73 miles (117 km) from the canal basin at Northumberland, Pennsylvania, at the confluence of the West Branch Susquehanna River with the main stem of the Susquehanna River, north through Muncy, then west through Williamsport, Jersey Shore, and Lock Haven to its terminus in Farrandsville. At its southern terminus in the Northumberland basin, the West Branch Canal met the North Branch Canal and the Susquehanna Division Canal. Through these connections to other divisions of the Pennsylvania Canal, it formed part of a multi-state water transportation system including the Main Line of Public Works.Between Northumberland and Muncy, the canal lay east of the river. Beyond Muncy, where the river makes a right-angle turn, the canal lay to the north. Started in 1828 and completed in 1835, it had 19 lift locks overcoming a total vertical rise of about 140 feet (43 m). The locks, beginning with No. 13, slightly upstream of the Northumberland Canal Basin, and ending with No. 34 at Lockport, across the river from Lock Haven, included two guard locks and an outlet lock in addition to the 19 lift locks.The state intended to extend the West Branch Canal from Farrandsville further upstream along the West Branch Susquehanna River to the mouth of Sinnemahoning Creek. Plans called for 33 miles (53 km) of canal, but the project was abandoned along with the idea that the West Branch Canal would eventually connect to the Allegheny River in western Pennsylvania.

The West Branch Susquehanna River is one of the two principal branches, along with the North Branch, of the Susquehanna River in the Northeastern United States. The North Branch, which rises in upstate New York, is generally regarded as the extension of the main branch, with the shorter West Branch being its principal tributary. The West Branch, which is 243 miles (391 km) long, is entirely within the state of Pennsylvania, draining a large mountainous area within the Allegheny Plateau in the western part of the state. Along most of its course it meanders past mountain ridges and through water gaps, forming a large zigzag arc through central Pennsylvania around the north end of the Allegheny Mountains. In colonial times the river valley provided an important route to the Ohio River valley. In the 19th century, its lower valley became a significant industrial heartland of Pennsylvania. In the 20th century, the upper reaches of the West Branch turned a yellow/orange color due to sulfurous drainage from nearby and abandoned deep bituminous coal mines.

With a garrison of over 300 troops and walls specially constructed to resist artillery, it presented a formidable defense and was never attacked.
