The table below is continually updated with the most current information on recreational use health advisories issued and lifted throughout the season for monitored and sampled water bodies.
Remember: Only a fraction of all water bodies in Oregon are visually monitored or sampled due to limited physical and monetary resources. A water body with no recreational health advisory is not an indication that a bloom is not present. You are your own best advocate when ensuring your safety, and that of your family and pets.
Be aware and
"when in doubt, stay out."
OHA has issued a recreational use advisory for the area around Eagle Point in Upper Klamath Lake in Klamath County. This advisory is due to elevated levels of a toxin associated with harmful algae blooms called microcystin. The levels measured are 61 parts per billion, which is well above our recreational use threshold level of 8 parts per billion. For more information and ways to reduce exposure, please see our news release. OHA will update this advisory as new information becomes available.
