The beach is accessible from 8:30 to 5 on weekdays only, and this schedule may vary depending on events or field trips at the learning Centre. The Philip Merrill Environmental Centre, headquarters to the Chesapeake Bay Foundation, is a favourite destination for school and learning groups The centre is considered one of the most energy-efficient buildings in the world and its design is a reflection of the foundation’s mission to promote protection and restoration of Chesapeake Bay.

A beach will also be posted if results from an area that has been resampled 5 times due to high levels of bacteria come back with results over 35 MPN colonies / 100 ml of water.

A beach is marked Grey when there is no current or reliable monitoring information available.

Maryland Healthy Beaches notification system has partnered with Google Earth to send updates. However, Swim Guide prefers to contact the Health Department directly as we are unable to determine the monitoring schedule Google Earth uses. The Anne Arundel Department of Health operates a 24-hour automated test results phone line at 410-222-7999.

A “no direct water contact” advisory is placed on beaches for 48 hours after a heavy rainfall, however the Anne Arundel County Department of Health’s website and The Maryland Healthy Beaches website are not updated.
