JEFFERSON COUNTY, OR -- The Oregon Health Authority has issued a health advisory for Lake Billy Chinook, southwest of Madras. Water monitoring confirmed the presence of blue-green algae and the toxins they produce, which can be harmful to humans and pets.
Those who draw in-home water from the Lake Billy Chinook Reservoir are encouraged to use an alternate source until the advisory is lifted. Boating is safe as long as speeds do not create excessive spray, which could lead to inhalation risk.
Officials say, with proper precautions to avoid water contact, other activities at Lake Billy Chinook are safe and encouraged.
