The Oregon Health Authority has lifted the health advisory posted Sept. 20 for the Link and Klamath rivers downstream to Keno Dam.
Water monitoring has confirmed that the level of toxin produced by blue-green algae are below guideline values for human exposure. However, OHA officials advise recreational visitors to always be alert to signs of algae blooms in all Oregon waters, because blooms can develop and disappear throughout the season. Only a fraction of the many lakes and waterways in Oregon are monitored for blue-green algae by state, federal and local agencies; therefore, you are your own best advocate when it comes to keeping you and your family safe.
People and especially small children and pets should avoid areas where the water is foamy, scummy, thick like paint, pea-green, blue-green or brownish-red, 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.
