ADVISORIES:

A Blue-Green Algae warning continues for Tenmile Lakes in Coos County, Fern Ridge Reservoir, Lost Creek Lake,  and  at Devils Lake. Water monitoring has confirmed the presence of blue-green algae that can produce toxins, state public health officials said. The algae levels are likely associated with dangerous cyanotoxin concentrations in the water that can be harmful to humans and animals. Swallowing or inhaling water droplets, as well as skin contact with water, should be avoided according to the authorities.
