Health Advisory issued for Avondale Lake

A second North Idaho lake has tested positive for blue-green algae, which can produce dangerous toxins. A health advisory was issued Tuesday for Avondale Lake by the Panhandle Health District and the Idaho Department of Environmental Quality. An advisory for Fernan Lake is also in effect. People should avoid swallowing or inhaling the lake’s water and to avoid direct contact with water containing visible algae. Consuming water containing high levels of blue-green algae toxins has been associated with damage to the liver and nervous system. Children and pets are particularly susceptible. If people eat fish from the lake, they should remove all fat, skin and organs before cooking to reduce their exposure risk. Excess nutrients associated with algae blooms often are caused by pollution from human activities. Idaho DEQ is working with residents and landowners on nutrient reduction projects.
