[2][3] The Susquehanna Boom was a system of cribs and chained logs in the West Branch Susquehanna River, designed to catch and hold floating timber until it could be processed at one of the nearly 60 sawmills along the river between Lycoming and Loyalsock Creeks in Lycoming County, Pennsylvania in the United States.

The Susquehanna Boom was originally built under the supervision of James H. Perkins,[4] and operated from 1851 to 1909, when it shut down for lack of timber.

The Hiawatha is run by River Valley Transit, which also operates bus and tourist trolley service in Lycoming County.

A dam on the West Branch Susquehanna River at Hepburn Street in Williamsport provides 652 acres (264 ha) of water deep enough for waterskiing.

Common species of fish (both cold and warm water) include catfish, panfish, and smallmouth bass.
