Toxic algae alert issued for reservoir near Heppner

Officials with the U.S. Army Corps of Engineers have issued an alert for high levels of toxin-producing blue-green algae in Willow Creek Reservoir near Heppner.

Water sampling confirmed a bloom of blue-green algae in concentrations that can produce toxins harmful to humans and animals.

Corps officials have 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.

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 because of wind and waves and are visible as masses of green, yellow or bluish-green slime.

Exposure to toxins can produce 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 also should get medical attention if they persist or worsen.

Children and pets are particularly susceptible.

Monitoring will continue in the reservoir until the levels of toxic algae decline enough to meet state guidelines, officials said.

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.
