Recreational Water Advisories/Closings

Last updated: February 7, 2023

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.

Warning: 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.

Preemptive AdvisoryPreemptive Rainfall Advisory
After rainfall of 1/2 inch or more, all Anne Arundel County beaches are under a no swimming/no direct water contact advisory for at least 48 hours due to predicted elevated bacteria levels from rainwater runoff and increased health risks. Do not swim in cloudy, murky water. During the summer swim season, the Recreational Water Quality Monitoring Program will resume its routine sampling following the 48-hour period.
Water Closed SignEmergency Closing
The Department of Health issues a closure when a sewage spill, leak or other problem indicates human waste has impacted the water.
Water Advisory SignHealth Advisory
The Department of Health issues advisories against direct water contact when routine sampling results exceed the EPA acceptable standard for enterococci bacteria or a harmful algae bloom has been identified.

The Department of Health has ordered recent closings, issued advisories or conducted assessments for the County waterways listed below:


8.6.21 – Water Advisory Lifted for North Branch of Cypress Creek (Advisory Issued 7.28.21)

August 6, 2021 — The Anne Arundel County Department of Health has lifted the closing of the North Branch of Cypress Creek off of the Magothy River in Severna Park due to a sewage spill that occurred on July 28, 2021.

It is estimated that 70,000 gallons of sewage was discharged from the Cape Arthur 5 pumping station and caused direct impact to the North Branch of Cypress Creek.

The closure was in effect for one week following the spill. There were no beaches located in the impacted area or water quality background history, therefore a sampling did not occur. The area was posted by the Anne Arundel County Department of Public Works.

May 26, 2021 – The Anne Arundel County Department of Health has lifted the advisory against swimming, kayaking, paddle boarding and other direct water contact for Elizabeths Landing, Lombardee Beach and Sunset Beach on Stoney Creek. The advisory was due to a 6,500-gallon wastewater spill on May 23 that resulted from a force main break on Nabbs Creek Road in Glen Burnie.

On May 24, the Department of Health collected water samples from Elizabeths Landing and Sunset Beach, the two Stoney Creek beaches that are part of the seasonal recreational water quality sampling program. Results received today show the following acceptable bacterial levels for swimming and other direct water contact.

Elizabeths Landing: 2 (most probable number of bacteria colonies) per 100 milliliters of water

Sunset Beach: 3 (most probable number of bacteria colonies) per 100 milliliters of water

The EPA acceptable standard is 104 or fewer enterococci bacteria colonies per 100 milliliters of water. Enterococci bacteria come from the intestines of all warm-blooded animals and are associated with fecal contamination.

[showhide type=”7_3_19_” more_text=”7.3.19 – Direct Water Contact Advisory For Lake Waterford Due to Harmful Algae Bloom (Advisory Lifted 10.16.19)” less_text=”7.3.19 – Direct Water Contact Advisory For Lake Waterford Due to Harmful Algae Bloom (Advisory Lifted 10.16.19)”]

October 16, 2019 – The Anne Arundel County Department of Health has lifted a harmful algae bloom advisory against direct water contact for Lake Waterford in Pasadena. The Maryland Department of the Environment has reported the latest microcystin result for Lake Waterford is 2.0 ppb (parts per billion), which is significantly below the state water contact advisory threshold of 10 ppb.

The blooms of blue-green algae reported on July 3, 2019 at Lake Waterford naturally occur in fresh waters and in Maryland’s Chesapeake Bay. However, the blooms are in nutrient rich environments and can become harmful when they occur in high concentrations or if they produce toxins.

When bathers see bright green waters, sometimes with a surface scum that resembles green paint, they are advised to take the following precautions:

  • Do not wade, swim or drink in areas where a blue-green algae bloom is evident.
  • If contact is unavoidable, wash body and clothes with clean, warm soapy water.
  • If there is skin irritation after contact, see a health care provider.
  • Keep pets away from bloom areas. Pets should not ingest or come in contact with water during a bloom. Questions regarding any suspected symptoms in pets should be directed to a veterinarian.
  • If you decide to eat fish caught from waters affected by a blue-green algae bloom, remove the fat, skin and organs before cooking. Be careful not to cut into the organs. Before cooking or freezing the fish, rinse the fillets with clean water to remove any contaminants from the cleaning process. Cook fish thoroughly.

More information about blooms can be found on the Maryland Department of Natural Resources website: http://dnr.maryland.gov/waters/bay/Pages/algal_blooms/Algae-Bloom-FAQ.aspx. To report human illness from bloom water contact, call the Bay Health Hotline at 877- 224-4229.

The Department’s most recent water samples show bacteria levels at the five beaches to be at acceptable levels that meet the U.S. Environmental Protection Agency standard.

For the most recent water quality report, click here. The report lists beaches that are tested regularly during the summer as part of the Department’s recreational water quality sampling program.

Reminder: After rainfall of 1/2 inch or more, all Anne Arundel County beaches are under a no swimming/no direct water contact advisory for at least 48 hours due to predicted elevated bacteria levels from rainwater runoff and increased health risks. Do not swim in cloudy, murky water.

DEBRIS

If your local community beach has debris, you are advised against swimming and other direct water contact until the debris stops washing ashore, a cleanup has been done and the water has cleared. More Information: Beaches and Debris Cleanup Safety

Anne Arundel County Executive Steve Schuh has announced that the County Department of Public Works (DPW) will assist in cleaning debris off community beaches as a result of the recent Conowingo Dam release. DPW is assessing private beaches and will contact communities to schedule the drop-off and retrieval of dumpsters. Communities with private, bayfront beaches can request an assessment from DPW by calling 410-222-7321 or emailing pwcust00@aacounty.org.
