Fly fishing in the snow

Hi Folks, Had a group of aspiring fly anglers yesterday afternoon on the Lamoille.  Was a cold day to fish with day time air temperatures barely exceeding 40 degrees.  The river temperature was 47 degrees and the level was jus below the seasonal average flow.  A few good snow squalls pushed through during our time on the water which was interesting.  Lots of leaves and junk in the water now as the foliage descends to the ground. A decent hatch of #22 BWOs, but not trout responding to the tiny may fly on the surface.  We fished slowed sections of river as the fish tend to hold in these areas as the water cools.  We swung buggers, bunny fur streamers and small #20 BWO nymphs with not a lot of action.  We missed 4 trout that ate the tiny may fly nymph.  Always slow it down when it cools.  Looks like things are winding down as the rivers cool off.  Any warmer days over the next week will be the ideal time to get on a river and chase river trout.  Not so sure the water temperature will exceed the magic number 50 degrees again this season.  Trout fishing again today and it will require some warm long johns.  Remember to clean your gear and keep the non-native species at home.  Have Fun, Willy
