Sunshine causing algae blooms in Western Washington waters

OLYMPIA – Sunshine is making many of us feel happier in the Northwest, but it’s also causing algae blooms in Western Washington waters.

The Washington Department of Ecology (Ecology) and many other jurisdictions are currently monitoring algae concentrations in both fresh and marine waters.

Blooms are occurring in lakes in Jefferson, Mason and Thurston counties.Jefferson County’s Anderson Lake is currently closed to use because of a toxic algae bloom. Local health officials advise people to stay out of and off the lake.

Marine water algae blooms are rearing up in Puget Sound’s Budd Inlet, in Sinclair Inlet and in the central Sound north of Vashon Island. Ecology’s Marine Monitoring Program displays recent aerial photos of Puget Sound online. Many of the photos are showing algae blooms. See the images atEyes Over Puget Sound.

An algae bloom is the visible appearance of millions of tiny plant-like organisms in the water. As spring and summer weather commences, people may encounter waters with visible algae blooms while they are enjoying the outdoors. Blooms are naturally occurring and common during sunny weather.

Some types of blooms can produce toxins that can make people sick if they are exposed to the toxins. This is especially true for small children and the elderly. Pets can die after drinking water with a toxic bloom.

Toxins also affect shellfish. Know before you dig. Call the Shellfish Safety Hotline, 1-800-562-5632 begin_of_the_skype_highlighting 1-800-562-5632 end_of_the_skype_highlighting, to find out which recreational shellfish beaches are closed.

Other types of blooms may not be toxic, but can be an environmental concern because when algae die, they sink and decay, which strips oxygen from the water. Aquatic life needs oxygen to survive.

Sometimes algae blooms look like spilled paint, oil or sewage. The public canreport any suspected spill or algae bloom to the state at Ecology’s website, or by calling 800-OILS-911 begin_of_the_skype_highlighting 800-OILS-911 end_of_the_skype_highlighting.

Nutrients that get into our waters feed algae blooms. Nutrients, which are substances that contain nitrogen and/or phosphorus, come from a complex variety of natural and human sources and pathways, including wastewater treatment plants, septic systems, groundwater, rivers, fertilizers and polluted runoff.

People can help keep nutrients out of Washington waters.

  • Your yard – Reduce the use of fertilizers and don’t overwater.
  • Your dog – Scoop, bag and trash dog poop.
  • Your home septic tank – Check it, fix it, maintain it.
  • Your baby – Keep dirty diapers out of the water.
  • Your automatic dishwasher – Use low or no-phosphate soaps, especially if you live on a lake and you use a home septic system.
  • Your car – Don’t feed soap to the storm drain. Wash your car on the lawn or at a commercial car wash.
