Blue-green algae toxins not found in South Tenmile Lake sample. The Oregon Health Authority has lifted the health advisory issued June 12 for South Tenmile Lake, located 10 miles north of North Bend in Coos County. Water monitoring has confirmed that the level of blue-green algae toxins are below guideline values for human exposure, and that the water does not present a problem for pets. 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.
