Reduced blue-green algae, toxin levels confirmed; continued caution with pets advised
The Oregon Health Authority has lifted the health advisory issued July 28 for Howard Bay and updated September 1 to include all of Upper Klamath Lake, located northwest of Klamath Falls in Klamath County.
Water monitoring has confirmed levels of blue-green algae and the toxins they produce are below guideline values for human exposure. However, OHA officials recommend people continue to be cautious about allowing pets in the lake because blooms can develop and disappear throughout the season. Federal, state and local agencies are able to monitor only a fraction of Oregon’s lakes and waterways for blue-green algae, so people should be their own best advocates when it comes to keeping themselves, their families and their pets 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 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, avoid activities that cause you to swallow water or inhale droplets, such as swimming or high-speed water activities.
