Fly fishing in the rain

Hi Folks, Guided a wet one yesterday afternoon.  Fly fished on the upper Lamoille where the water was a nice cool 57 degrees.  Levels have stabilized and yes we still need more rain.  It looks like the cool weather will be moving out and more summer like conditions moving in.  The saving grace is that our night time air temperatures will be cool which allows the rivers to cool off a bit each night.  Fished some pocket water and riffles to pools yesterday afternoon into dusk.  There were a number of #14 egg laying caddis, but no trout rising to them.  We caught a couple of small wild rainbows on a #14 Ausable wulff in some pocket water and landed stocked trout in the riffles to pools nymphing.  The nymph rig was a #16 olive caddis with a #14 zug bug.  The stockies ate both patterns.  The rain started out lightly and then really increased.  The fishing seemed to slow when the rain picked up.  Was hoping for risers at dusk but not yesterday.  I did see some large Drake spinners two days ago on a still body of water I was guiding for bass.  I think it is safe to say that it is now time to look for the large may flies on all of our cold water lakes.  Will be drifting for the next few days.  Remember to clean your gear and keep the non-native species at home.  Have Fun, Willy
