Harmful Algae Bloom Advisories
OHA advises the public when a harmful algae bloom is detected in a lake or river. Not all blooms are harmful, but blooms caused by cyanobacteria can produce toxins that cause serious illness in pets, livestock, wildlife and humans. Only a fraction of Oregon waterbodies are monitored due to limited resources, so remember "when in doubt, stay out."
If there are current algae advisories, they will be listed below. Visit our Algae Bloom Advisories page for details.
Permanent Advisory: Avoid pools of water in bedrock along the South Umpqua River
Beach water is sampled from Memorial Day through Labor Day at designated locations for high levels of bacteria to let visitors know when there is a health concern.
If there are current beach advisories, they will be listed below. Visit our Beach Water Quality site for more information.
