Toxic Algae Advisories: Detroit Lake Advisory Lifted

Be on the lookout for waters that look suspicious — foamy, scummy, thick like paint, pea-green, blue-green or brownish red. When in doubt, stay out!

Health advisories for toxic algae levels have been issued for the following bodies of water in Oregon:

Current Advisories

  • Detroit Lake, located 46 miles southeast of Salem on the North Santiam River in Linn and Marion Counties LIFTED 5.21.15

Note: The U.S. Army Corps of Engineers will no longer test the water of 11 reservoirs in Oregon for toxic algae. These bodies of water are: Lost Creek Lake in Southern Oregon, Dexter, Dorena, Fall Creek, Fern Ridge, Lookout Point, Hills Creek, Detroit, Cougar and Blue River reservoirs in the Willamette River Basin, as well as Willow Creek reservoir in Eastern Oregon. Personal visual observation of the signs of toxic algae is important to keep children and pets safe.

Children and pets are particularly susceptible to this toxin

Exposure to toxins can produce symptoms of numbness, tingling and dizziness that can lead to difficulty breathing or heart problems and require immediate medical attention. Symptoms of skin irritation, weakness, diarrhea, nausea, cramps and fainting should also receive medical attention if they persist or worsen. Children and pets are particularly susceptible.

Swallowing or inhaling water droplets should be avoided, as well as skin contact with water by humans or animals. Drinking water from these bodies of water is especially dangerous. Oregon Public Health officials advise campers and other visitors that toxins cannot be removed by boiling, filtering or treating the water with camping-style filters.

Oregon Public Health recommends that people who choose to eat fish from waters where algae blooms are present should remove all fat, skin and organs before cooking since toxins are more likely to collect in these tissues. Additionally, public health officials advise that people should not eat crayfish or freshwater shellfish harvested from these bodies of water while this advisory is in effect.

A hazard for dogs

Dogs have become very sick and even died after swimming in and swallowing water affected by toxic algae. If you find thick, brightly colored foam or scum at a lake, pond or river, don’t let your pet drink or swim in the water. Avoid contact with the water, as toxins can be absorbed through the skin.

If your dog goes into the water:

  • Don’t let your pet lick its fur
  • Wash your pet with clean water as soon as possible
  • If your dog has symptoms such as drooling, weakness, vomiting, staggering and convulsions after being in bloom-affected water, call your veterinarian immediately.
