OHA release - PORTLAND, Ore.—Oregon Health Authority (OHA) issued a recreational use health advisory today for Agency Lake due to the presence of cyanotoxins above the recreational use value (RUV).  A recreational use health precaution has been in place since May 21 due to the presence of a visible harmful algae bloom. The lake is in Klamath County.  People should avoid swimming and other water activities with a high risk of swallowing water or inhaling water droplets in areas of the lake where blooms are present. Ingestion or inhalation of water is the exposure route of concern. Toxins are not absorbed through the skin. However, those with skin sensitivities may get a puffy red rash.  OHA’s RUVs are designed to protect the most vulnerable, including children, who have a higher activity level and are more likely to swallow water while recreating.  OHA encourages people to visit Agency Lake and enjoy activities such as fishing, camping, hiking, biking, picnicking, bird watching, canoeing, and kayaking. Boating is safe as long as speeds do not create excessive water spray. Sprays could lead to the risk of inhaling cyanotoxins.
