Winter Fishing Update: Big Thompson 

With the cold weather in full swing, the Big Thompson is a great option for those looking to continue fishing through the winter.  Focus on deep pockets and slower-moving water as fish will congregate deep in the pools. Technical nymphing is the name of the game, use small midge and baetis patterns (Sizes #20-24). We like running a Hot-Headed Sow Bug (Sizes #18-20) in front of a small midge or baetis pattern. Our favorite midge and baetis patterns include the Pure Fire Midge, Juju Baetis, and Top Secret Midge. Before you worry about changing flies, think about changing weights or using smaller tippet and indicators. The clear water means that they fish are more sensitive to disturbances on the surface. Yarn indicators can be a great method to avoid spooking fish. Remember that if you can see the fish better, the fish can you see you better too!
