Temperatures are warming in Lake Coeur d'Alene, according to Bay Watchers data compiled between May 28 and Oct. 15, 2024, for Rockford Bay, Cave Bay, Leaning Pine Point and Cottonwood Bay. Warming even 3 degrees can change the ecology of a lake, including potentially creating better for algae to flourish. Eutrophication of the water can occur when the amount of nutrients increases too far and feeds invasive algae blooms.
