Most lakes and beaches in Whatcom County are usually safe to swim and recreate in, but when there are toxins, pollution, or other health issues in the water we post signs to let you know.
Lakes in Whatcom County are generally healthy to play or swim in. We do not regularly monitor freshwater lakes, but we do respond to questions or concerns by collecting and testing water samples. If we discover a health risk, we post signs at public access points. To report a concern with a lake or beach email us or call 360-778-6000.
Freshwater lakes may have issues with "Swimmer’s Itch" or toxic algae blooms. Animals may poop on the shore or in areas where water runs into the lake. Water contaminated by poop may have bacteria, parasites, or viruses that could make you sick.

Beaches in Whatcom County are often used for recreational shellfish harvest. We work with the Washington State Department of Health to monitor for toxins that are often present in shellfish. When toxin levels are too high, we close the beach to shellfish harvesting and post signs to let you know. Closure signs can be damaged or stolen, so you should always check beach status before collecting shellfish.
