humid fly fishing for trout

Hi folks, guided a full day yesterday with the fly rods on the Lamoille and one of its tributaries.  Water temperatures did not change much from the Lamoille to the tributary we visited.  The water temperature was 66 to 67 degrees.  Pretty muggy day with heavy air and we had to hold up under some soft woods for 15 minutes at lunch time due a quick moving thunderstorm.  I though the water levels were perfect for fishing.  We nymph fished for the most part and my guests were fine fly anglers who could handle a rod.  We did see a few #12 Isonychia hatch but only a couple of random rising fish.  We drifted a #14 zug bug with a #18 olive caddis pupa under and indicator.  Also threw a prince nymph in the mix and caught fish on both fly patterns.  We picked up fish dead drifting as well as swinging the fly.  At days end we tried a #14 green foam terrestrial pattern with a caddis pupa dropper and caught a wild bow on the dry.  All wild rainbows yesterday with 1 brook trout in the mix on the last cast of the day.  All said we landed 13 fish and missed or lost just as many.  We did do some walking and cover some water.  No really big trout, but lots of fish between 7" and 12" and good fun on small stream fly rods.  The fishing seemed more consistent in the tributary we visited versus the Lamoille.   Looks like the muggy weather will push out of here but not before we receive some heavy rain today.  Remember to clean your gear and keep the non-native species at home.  Have Fun, Willy
