A health advisory at Cullaby Lake has been lifted after testing found reduced levels of toxins from harmful algae.
The Oregon Health Authority said cyanotoxins are below the recreational guidelines for human exposure. But the water in the lake near Warrenton is still unsafe for dogs or other pets.
“Although the advisory has been lifted, conditions can change rapidly due to changes in weather and nutrients in the lake,” the health authority said in a statement. “People should always be aware that blooms can develop on any water body under the right environmental conditions and can grow and disappear throughout the season.”
The advisory was issued in late August.
