The Chesapeake Bay Small Watershed Grants Program promotes community-based efforts to develop and implement conservation strategies to protect and restore the diverse natural resources of the Chesapeake Bay and its watershed. The program provides grants to local governments and community organizations working to improve the condition of their local watersheds while building citizen-based resource stewardship. The program has been designed to encourage the sharing of innovative ideas among the many organizations wishing to be involved in watershed protection activities.

This map shows progress toward achieving the Chesapeake Bay Program segment-specific underwater bay grass restoration goals. It is based on the single best year of acreage as observed through the most recent three years of data from the Chesapeake Bay underwater bay grasses aerial survey.

American shad were once the most abundant and economically important species in the Chesapeake Bay. Shad are anadromous fish and spend most of their lives in the ocean, returning to freshwater rivers to spawn after they reach maturity. Data for the York and Potomac Rivers were provided by the Virginia Institute of Marine Science via an ongoing Catch per Unit Effort (CPUE) study involving American Shad gill-netting. Data for the Susquehanna and James Rivers represent published fishway passage values for Conowingo and Boshers Dams, respectively.
