The flows on the Big Thompson have been steady around 50 cfs the last couple of weeks. Dry flies have been producing really well recently. BWO's, caddis, and midges have been the main hatches we have been seeing on the Big T. There are still a few hoppers and terrestrials along the rivers edge, so throwing small chubby chernobyl and hopper patterns will continue to produce until the fall weather sets in. When the fish are eating dries off the surface, a double dry fly rig is a great way to fish. A larger dry in the front will help you see where the smaller one behind it is. Nymph rigs and dry droppers will find some fish when they aren't actively rising. Smaller caddis and BWO nymphs such as The Ticket #14-18, Juju Baetis #18-20, and #18-22 Sparkle Wing rs2. Let us know if you have any questions or looking for more info on fishing the Big Thompson!
