Beach Advisories

Beach water is sampled for high levels of bacteria to let visitors know when there is a health concern. Beaches are monitored from Memorial Day in May through Labor Day in September. Read more about Oregon's Beach Monitoring Program.

  • Beach monitoring for 2015 will begin on Memorial Day (May 25).

Harmful Algae Bloom Advisories

OHA advises the public when a harmful algae bloom has been detected in a lake or river. Not all blooms are harmful, but when a bloom is caused by cyanobacteria, toxins may be present that can cause serious illness in pets, livestock, wildlife and humans. Browse the list below or view maps and more details about current and previous advisories.

Fish Consumption Advisories

Fish advisories are designed to help you gain the health benefits of eating fish while protecting you and your family from contaminants that are sometimes found in fish.
