Flows at the Big T have been pretty variable this winter, at times bumping up to between 25-30 CFS and currently back down in the skinnier 15 CFS range. You're likely to do best at the Big T below the dam in February with small midges on a light nymph rig. Think size 22-26; patterns like the disco midge, bling midge, top secret midge, and zebra midge will always be consistent players. If you see fish rising, try small midges dries and emergers like griffith's gnat, matt's midge, sprout midge, dark RS2, etc. Sometimes a #24-26 blood midge is a killer at the tailwater in the wintertime. The canyon, aside from just the upper mile or two, tends to get pretty locked up in the wintertime. If you head down into the canyon, look for the water that's moving and receiving the most sun. Other bugs that are always worth a try on here in the wintertime include small san juan worms in #16-18, small leeches, pheasant tails, blue poison tungs, sparkle wing RS2s, and even small caddis larvae and soft hackle sow bugs as we get closer to March and especially when flows come up.
