Answer
Maryland Coastal Bays Program and partners publish water-quality and seagrass health data used for stewardship education—not daily swim advisories like some inland lakes. After heavy rain, runoff can cloud bays and increase bacteria near storm drains; use common sense before immersion. Ocean Beach Patrol flags do not govern bay swimming.
