Reduced blue-green algae and toxin levels confirmed; continued caution with pets advised
June 16, 2017
The Oregon Health Authority has lifted the health advisory issued June 2 for Detroit Lake, located 46 miles southeast of Salem in Marion County.
Water monitoring has confirmed that the level of blue-green algae toxins are below guideline values for human exposure. However, the Oregon Health Authority recommends that people continue to be cautious with their pets in the lake because toxins are still above the very low exposure levels established for dogs.
Oregon health officials advise recreational visitors to always be alert to signs of algae blooms in all Oregon waters, because only a fraction of the many lakes and waterways in Oregon are monitored for blue-green algae by state and federal agencies. People and their pets should avoid areas where the water is foamy, scummy, thick like paint, pea-green, blue-green or brownish red in color, if a thick mat of blue-green algae is visible in the water, or bright green cells are suspended in the water column. If you observe these signs in the water you are encouraged to avoid activities that cause you to swallow water or inhale droplets, such as swimming or high-speed water activities.
