Pennsylvania in the Chesapeake
Half of the land area of Pennsylvania drains to the Chesapeake Bay from four major river basins, and Pennsylvania comprises 35 percent of the entire Chesapeake Bay Watershed.
The Susquehanna River is the largest tributary to the bay, providing 90 percent of the freshwater flow to the upper bay and half of the total freshwater flow to the bay.
30 Coalition members are located in Pennsylvania.
