The lower river now features a great BWO emergence. The same should happen soon on the upper river. During cloudy times like today, this will be a day long event resulting in good action. As we move further into autumn, streamers will become more important in such spots as Box Canyon, below Ashton Dam, Chester backwaters, below Chester Dam, and around St. Anthony. So be sure to have streamers in that fly box when you visit the “Fork” this time of year.
