Thewater supply for Montour County comes primarily from the Susquehanna River, as well aswells andsprings. The rural areas especially depend on wells for their water supply, but Danville mostly uses the Susquehanna River.

However, the Keyser, Wills Creek, and Tonoloway Formations are considerably better at producing water.[8]
