Winter has been tougher than usual this year. With lower temps. than we have seen in a couple of years, it has the stream temps. low. Though the streams are averaging 36-38 degrees this month, the fish are still able to be coaxed into biting, The best tip I can give right now is to make certain your fly stays on the bottom. The fish are slow and sluggish, so drift slower than normal. Mind your mends to keep a natural drift. Try using patterns such as, a BH Pheasant Tail, sz. 12-16, Gold-Ribbed Hare's Ear, sz. 12-18; BWO nymphs and emergers, sz. 16-24, as well as atractor patterns like the Y2K, sz.12-16. In higher flows, try using bigger patterns like a Wooly Bugger, sz.4-10, in various clors, or baitfish streamers, like a Muddler Minnow, Black-Nosed Dace, etc., sz. 6-10. Just remember to SLOW IT DOWN.
