Latest Update: 03/28/19 -- The Big Thompson is a fantastic option this time of year. Like any tailwater, the river is chalked full of midges and baetis. The tailwater meadow below Lake Estes is still going to be your best bet but the water is opening up in the canyon. Focus on fishing the deep runs and you are sure to run into a few trout. Don't be surprised if you hook into a big fish, this stretch of river is notorious for holding some very large trout. Use baetis patterns such as a juju baetis or a sniper baetis in sizes #20 and #22 as your lead fly. Trail these flies with midges in size #22 and #24. It is always a good idea to have an assortment of midges in red, black, olive, and cream. You may also come across a little dry fly action so be prepared with a tandem dry fly rig. A good place to start is a Parachute Adams with an emerger pattern trailing just below the surface about 12-16 inches behind.
