Health advisory lifted for Coffenbury Lake

Warnings were posted around Coffenbury Lake near Fort Stevens State Park last summer because of the presence of blue-green algae.

Coffenbury Lake in Fort Stevens State Park is safe for people again, but the water is still dangerous for dogs.

The Oregon Health Authority lifted a health advisory on Wednesday that it had issued in July over blue-green algae and the toxins they produce. Tests showed levels have fallen below state guidelines for human exposure. Toxin levels remain above the very low exposure levels established for dogs, said Rebecca Hillwig, a state natural resource specialist.
