The map and table below are continually updated with the most current information on advisories issued and lifted throughout the season for monitored water bodies.
Remember: Only a fraction of all water bodies in Oregon are monitored due to limited physical and monetary resources. A water body with no 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."
Douglas County Permanent Health Advisory:
South Umpqua River and Lawson Bar
Pools in the bedrock along the rivers edge are known to develop cyanobacterial (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.
