The Oregon Health Authority issued a recreational use health advisory today for Lake Selmac due to the presence of a cyanobacterial (harmful algae) bloom and cyanotoxins (harmful algae toxins) above recreational guideline values for human exposure. The lake is in Josephine County. People should avoid swimming and high-speed water activities, such as water skiing or power boating, in areas of the [water body – lake, river, reservoir, etc.] where blooms are identified. Although toxins are not absorbed through the skin, people who have skin sensitivities may experience a puffy red rash. People are encouraged to visit [Water Body] and enjoy activities such as fishing, camping, hiking, biking, picnicking, and bird watching. Boating is safe as long as speeds do not create excessive water spray, which could lead to inhalation risk.
