Current Surface Water Advisories

The Surface Water Advisory Page was last updated on October 13, 2016.

When it comes to water, we work to identify and stop contamination, prevent waterborne illness and improve water quality. Protecting the water around us is essential to community health and quality of life.

If you would like to know when our local lakes and beaches are closed or when access is limited because of public health risks, sign up to receive emails and select Surface Water Advisories.

Toxic Algae Advisory

When you see a toxic algae advisory, it means the water has cyanobacteria, or blue-green algae, which can produce toxins. Add sunlight and warmer temperatures, and toxic algae can reproduce rapidly in fresh water—creating toxic algae “blooms.” Water with toxic algae can kill pets, waterfowl and other animals and cause serious illness or even death in people.

Lakes with advisories are generally checked weekly until advisory is lifted.

Shellfish Advisory

Why do we close recreational shellfish harvesting at local beaches? Causes can include high concentrations of shellfish biotoxins such as Paralytic Shellfish Poison (PSP), or because of reported illnesses from Vibrio, a bacterial foodborne infection usually associated with eating undercooked seafood. Sometimes, we close beaches because of bacteria from failing septic systems, poor animal keeping practices or storm-water runoff that results in poor water quality.

Swimming Beach Advisory

We post advisories at swimming beaches for everything from high bacteria levels to contamination from a sewage leak or toxic algae. Any of these can sicken people, pets and wildlife.

Do Not Eat the Fish Advisory (Click here for more info)

  • Because of pollution, people should not eat shellfish, including crab and bottom fish from the waterways of Commencement Bay.

Creeks and Streams Advisories

All rivers, streams, lakes and ponds naturally contain bacteria, viruses, parasites and algae. Most of these small organisms are beneficial and do not harm people, but some can cause illness. When bacteria counts are high, people who wade or play in a creek have an increased risk of getting sick. To prevent that, we post advisories when a creek has high bacteria counts.
