Beach Information

Responsibility

Under the Massachusetts Department of Public Health (MDPH) regulations for beach guidelines, beach operators must test all public ocean beaches for bacteria each week using the enterococcus indicator organism. Under that guideline beach sampling will be weekly during the swim season (June to September). Single-sample test results cannot exceed a specified number of bacteria colonies per 100/milliliter sample. If they exceed the specified levels the beach is required to be closed to swimming. The maximum contamination is 104 enterococci/100 milliliter for ocean waters. There are 3 recreational water bodies that the health department tests:

  • Black Rock Beach
  • Sandy Beach
  • Bassings Beach 

Beach Closings

When the beach is closed in the harbor, the Harbormaster will post a yellow flag for closed and all other locations will have a sign posted.

When Sandy Beach is closed the information is posted on the back of the lifeguard stands. When Black Rock Beach is closed the information is posted in a case at Wadleigh Park. BEACH 


BEACH CLOSING INFORMATION WILL ALSO BE POSTED TO THE TOP OF THE TOWN OF COHASSET WEBSITE
