Oregon Health Authority Update: A recreational use health advisory has been issued for parts of Detroit Lake and Big Cliff Lake.
This update lifts the advisory for all areas of Detroit Lake except for the area in and around the log boom, and extends the advisory from the log boom through Big Cliff Lake.
Detroit Lake is located 46 miles southeast of Salem. Big Cliff Lake is located along Oregon Route 22 below Detroit Dam.
Water monitoring has confirmed that levels of cyanotoxins (harmful algae toxins) above OHA advisory levels for human exposure were found in the log boom area of Detroit Lake and in Big Cliff Lake. Because high toxins are limited to these areas, OHA is able to target these areas for the advisory.
However, Oregon Health officials advise recreational visitors to always be alert to signs of cyanobacterial (harmful algae) blooms in all Oregon waters, because blooms can develop and disappear throughout the season. Only a fraction of the many lakes and waterways in Oregon are monitored for cyanobacteria by state, federal and local agencies. Therefore, you are your own best advocate when it comes to keeping you and your family safe while recreating.
In short, if the water is pea soup green, find another lake.
