The Wrightsville Dam was a 19th-century dam on the lower Susquehanna River between Wrightsville and Columbia, Pennsylvania.
The low-head dam was constructed in 1840 to impound the waters of the Susquehanna to provide a slackwater pool to allow the safe passage of canal boats from the Pennsylvania Canal on the Columbia (Lancaster County) side across the mile-wide rocky river to the Susquehanna and Tidewater Canal on the Wrightsville (York County) side.[1]
