Idaho Public Health officials are warning people and pets to avoid contact with waterways that may be contaminated with harmful algal blooms following an advisory for Elk Creek Reservoir and the closure of Hordemann Pond in Moscow.
The Idaho Department of Environmental Quality has been testing several other waterways that are suspected of contamination. Juries suggested those who plan on recreational activities in area waterways check the DEQ advisory map here before they head out.
Officials say algae blooms are typical this time of year, and can last until October, but some containing cyanobacteria, which thrives during hotter temperatures, can make people and animals ill — sometimes fatally.
The harmful algal blooms can come in many colors and are more typical in stagnant or slow-moving water, and signs of contamination include scum or film on the water that may have a multicolored, oily appearance. Blooms may also form thick mats along shorelines that can resemble pea soup and can have an unpleasant odor.
Anyone that suspects a body of water may be contaminated by a harmful algal bloom may report it to DEQ locally at (208) 799-4370, and personnel will be sent to test the water. (Public Health – Idaho North Central District)
