Protecting the Upper Susquehanna Basin also protects the Chesapeake Bay watershed. Efforts by the Upper Susquehanna Coalition and Chesapeake Bay Program include constructing wetlands for flood control and wildlife habitat, planning farm nutrient management, using rotational grazing to reduce stream siltation, guiding development to minimize water pollution, and restoring streamside areas to protect banks. People can help through household hazardous waste collection programs, river or stream cleanups, regular septic system pumping, planting native trees and shrubs along streams, and joining local watershed organizations. The Chesapeake Bay is the largest estuary in the United States, about 200 miles long, and its 64,000-square-mile watershed includes parts of New York, Pennsylvania, West Virginia, Virginia, Washington, D.C., Delaware, and Maryland, beginning in Cooperstown, New York. Wildlife in the watershed includes the bald eagle, river otter, mink, and great blue heron.
