Summer heat can cause dangerous conditions in Idaho’s rivers and lakes

Idaho News, Research
By Drew Pendleton; Dept. of Health and Welfare As temperatures increase, so does the likelihood of a cyanobacterial harmful algal bloom (cyanoHAB). CyanoHABs are caused by cyanobacteria, and the toxins they produce are harmful to humans, pets, livestock, and wildlife. CyanoHABs can change and increase rapidly if conditions are right. They favor warm water, sunlight, and specific nutrients in the water. These blooms can last throughout the summer into fall. The Idaho Department of Environmental Quality (DEQ) samples and analyzes Idaho water bodies for cyanoHABs. The test results are provided to the Idaho Department of Health and Welfare (DHW) and local public health districts, and they decide if a health advisory should be issued. For information on advisories, visit the DHW’s Idaho Recreational Water Advisories map for more information. The…

Health advisory issued for Fernan Lake in North Idaho, yet another cyanobacteria victim

Idaho News
Idaho Statesman Algae is pictured along the shore of Fernan Lake this month. A public health advisory was issued Thursday for Fernan Lake. The advisory, issued by Panhandle Health District in collaboration with the Idaho Department of Health and Welfare and the Idaho Department of Environmental Quality, states that recent water sampling indicates the presence of cyanobacteria, a harmful algae bloom, in the lake. The agencies are urging the public to use caution when recreating in or near the water, especially where ingestion is a risk. TOP VIDEOS × Cyanobacteria are a natural part of Idaho’s water bodies. When temperatures rise, their populations can bloom and toxic chemical compounds, or cyanotoxins, can be released into the water. Caution should be taken anywhere where the water appears discolored or murky as…
