BWOs are active almost everywhere during afternoons when shadows begin to extend. If we get into cloudy weather, fish will respond to BWOs in better numbers, and hatches will be more intense. It is also the time of year to present streamers for migrating browns. The section between Ashton Dam and Chester backwaters is a popular place to wade fish. There are also locations for wade fishing below Chester Dam downstream to below St. Anthony. From Warm River to Ashton Reservoir backwaters a boat will get you into the best fishing. Pattern choice is not critical at these locations so long as your fly box includes somber and bright ties.
