PORTLAND, Ore.—Oregon Health Authority (OHA) issued a recreational use health advisory today for areas around Eagle Point in Upper Klamath Lake due to the presence of a cyanobacteria bloom and cyanotoxins above recreational use values for human exposure. The lake is in Klamath County. People should avoid swimming and high-speed water activities, such as water skiing or power boating, in areas of the lake where blooms are, as the major risk of exposure is from ingesting water. These toxins are not absorbed through the skin. However, if you have skin sensitivities you may get a puffy red rash. Due to very hot weather between the time samples were collected and when OHA received results, people should be aware that the bloom and associated toxins may have spread beyond the area around Eagle Point. OHA recommends that people keep an eye out for visible signs of bloom in other areas of the lake and stay out of the water in locations with visible scum. People are encouraged to visit Upper Klamath 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.
