Oregon Health Authority (OHA) has lifted the cyanotoxin advisory for Devils Lake for humans. Water monitoring confirmed that the level of cyanotoxins in Devils Lake are below the recreational guideline values for people. However, levels detected are still above the OHA’s educational guide values for dogs, and owners should keep their pets away from these areas.
