PORTLAND, Ore. – The U.S. Army Corps of Engineers issued an algae advisory due to high levels of blue-green algae found in Willow Creek Reservoir, near Heppner, Ore.
Water sampling confirmed the presence of blue-green algae in concentrations which can produce toxins harmful to humans and animals. The Corps notified state and county health departments.
Swallowing or inhaling water droplets should be avoided, as well as skin contact with water by humans or animals. The toxins cannot be removed by boiling, filtering or treating water.
Exposure to toxins can produce symptoms of numbness, tingling and dizziness which can lead to difficulty breathing or heart problems and require immediate medical attention. Symptoms of skin irritation, weakness, diarrhea, nausea, cramps and fainting should also receive medical attention if they persist or worsen. Children and pets are particularly susceptible.
Blue-green algae plants occur naturally in lakes and are often associated with increased water temperatures and nutrients in lake water. Algal blooms are rapid buildups of algae that are often found near the shore due to wind and waves, and are visible as masses of green, yellow or bluish-green slime.
Monitoring will continue in the reservoir until the levels of toxic algae decline enough to meet state guidelines. Check for updates on the Corps’ Portland District Web site at http://www.nwp.usace.army.mil/.
With proper precautions to avoid water contact, people are encouraged to visit Willow Creek Reservoir and enjoy activities such as camping, hiking, biking, picnicking, catch-and-release fishing and bird watching.
Willow Creek Reservoir had a previous algae advisory in June, which was lifted Aug. 3.
