Pineview algal bloom

Health officials reported a harmful algal bloom in Pineview Reservoir on Friday, Aug. 31, 2018.

Health officials have confirmed the presence of a harmful algae bloom in Pineview Reservoir.

Staff with the Weber-Morgan Health Department confirmed the bloom late Friday afternoon. While they haven’t closed the reservoir, health officials advise against swimming and waterskiing in the area. Pets should be kept away from the reservoir and people should not ingest the water. Boaters should avoid scummy areas. Anglers should thoroughly clean fish and throw out entrails.

“The bloom has the potential to shift with the wind and temperatures so we are warning people (to) exercise caution, heed the warning signs and stay away from areas of scum,” said Michela Harris, director of Environmental Health, in a news release.

Blue-green algae forms in a mix of warm temperatures, sunlight and high nutrients. While other shallow water bodies in Northern Utah have experienced blooms in the past, like Ogden’s 21st Pond and Mantua Reservoir, this is the first reported harmful algae bloom in Pineview Reservoir.

Pineview is a popular area for boating, swimming and fishing. The reservoir was closed Thursday and Friday to assist firefighters with the Avon fire, which also limited human contact with the bloom.

Harmful algae blooms contain toxic cyanobacteria. Symptoms of exposure include skin rashes, nausea, vomiting, headaches and fever. Blooms are dangerous for humans, pets, fish and wildlife.

Those worried about human exposure should call the Utah Poison Control Center at 800-222-1222.
