The great news is that the devastating wildfire season in the northern rockies is nearly over. In addition to threatening homes and businesses, the fires have been a larger than normal stress on aquatic environments, including streams and lakes. The cold temps and precipitation will give those fish and those who call the river home– a much-needed cool off.
