Directly across the open Bay from Annapolis, Maryland is the Upper Eastern Shore region, comprised of the tidal Chester River as well as the Eastern Bay enclosed by Kent Island. Eastern Bay and the Chester River are connected at Kent Narrows. This area is vulnerable to nutrient pollution that causes large algal blooms, which in turn create deoxygenated dead zones. Historically, Eastern Bay and the Chester River have been home to oysters, catfish, striped bass, perch, and blue crabs. (Based on ShoreRivers.)
