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."
= Advisory in effect = Advisory has been lifted = Permanent advisory
Douglas County Permanent Recreational Use Advisory: South Umpqua River and mainstem Umpqua River
The advisory covers the South Umpqua River from Canyonville downstream to the confluence with the mainstem Umpqua River, and the mainstem Umpqua River downstream past Elkton to Lawson Bar. Pools in the bedrock along the rivers edge are known to develop cyanobacteria (blue-green algae) blooms that can be harmful to pets and people if accidental ingestion occurs. Signs have been posted at several access areas along the river.
