Current Report
Slough Creek is running very low right now, with flows looking nearly nonexistent in some of the pools. Fishing has been slow, and the bright, sunny days we’ve been having have kept the hatches few and far between. Fishing a single BWO dry to cruising fish has been the most effective approach, with some fish also showing interest in streamers. As we get further into fall, cloudy days should provide better opportunities for both BWO activity and surface feeding.
