Toxic Blue-green algae blooms reported at Brownlee Reservoir

Idaho Press-Tribune - 7/29/2017

Those visiting Brownlee Reservoir in the Snake River Canyon are advised to look out for blue-green algae booms. The water containing these toxic blooms may cause illness.

Officials with Southwest District Health and the Idaho Department of Environmental Quality issued a public health advisory for humans and pets on Friday afternoon, urging water-goers to stay away from areas where blooms can be seen. This type of algae was reported between mile markers 317 and 321.

Blue green algae occurs naturally, but when high concentrations lead to blooms, humans and pets should be cautious. In these conditions, the algae can release toxins into the water.

To spot blooms, look for surface scum resembling pea soup. Often it has an unpleasant stench.

Human symptoms due to blue-green algae blooms are rare, but they can cause nausea, vomiting, diarrhea, liver damage and neuro-toxic reactions such as tingling of the fingers and toes.

Pets and livestock should not be allowed near blue green algae. If pets drink or swim near this type of water, a reaction may require veterinary attention. If pets come into contact with the blooms, wash their coat with potable water immediately.
