Current closings and advisories are listed below.

Lab results from collected water samples take at least two working days to process. Closings and advisories remain in effect until results meet acceptable levels for one or more days. Acceptable levels are determined by the State, U.S. Environmental Protection Agency and the Anne Arundel County Department of Health.

Preemptive Advisory

After rainfall, all Anne Arundel County beaches are under a no swimming/no direct water contact advisory for at least 48 hours due to predicted high bacteria levels.


There is always an associated health risk from swimming in any natural body of water. Natural water bodies contain bacteria, viruses and other harmful microorganisms. Disease-causing microorganisms, such as Mycrobacterium marinum or Vibrio vulnificus can enter the body through open cuts, scrapes and wounds. Fact Sheets on Recreational Water Illnesses.
