WSSC has issued a  Water Contact Health Advisory for T. Howard Duckett and Triadelphia Reservoirs.   The water utility sent out the following information:

"We have detected high concentrations of blue-green algae in this reservoir, which can cause serious adverse health effects if contacted.

Those visiting WSSC’s Duckett and Triadelphia Reservoirs should be advised:

  • Water contact is not recommended. Rinse off immediately with clean water, if contact is made with reservoir water.
  • Do not allow pets to swim in or drink the water (prohibited at all times by WSSC watershed regulations).
  • Do not consume fish livers or digestive organs from fish caught in the reservoirs. Also, wash fillets thoroughly with drinking water.

Permit-holders are still able to use the picnic areas and hike on designated trails.

We are recommending that, in the event that you, someone you know or a pet has contacted or ingested water at either reservoir, please contact your local Health Department.

Be aware that this does NOT affect the drinking water.

For more information, call the WSSC hotline at 301-206-7011.
