PORTLAND, Ore. – The algae advisory issued in mid-August for Willow Creek Reservoir has been lifted, the U.S. Army Corps of Engineers announced today.
Recent water sampling confirms reduced levels of a species of blue-green algae that can produce toxins harmful to humans and animals, with the exception of the northwest corner of the lake, which continues to return high algal cell counts. State guidelines recommend waiting two weeks after algal cell counts fall below state-specified levels before lifting advisories related to algae blooms.
The Oregon Department of Human Services advises people who recreate in Oregon reservoirs to always be alert for signs of algal blooms. People and their pets should avoid water contact if there are visible clumps of algae in the water.
