escaping the heat

Hi Folks, Been guiding fly guests on small brooks the last couple of days.  A mountain stream is a great place to escape the heat and humidity.  Due to the tree canopy and coolness of the water the stream basin always seems about 10 degrees cooler than the surrounding area.  Mother Nature's air conditioning.  So water temperatures have risen significantly over the last few days, especially in the bigger rivers.  The Lamoille and Winooski currently are un-fishable from a stand point of the water being too warm (over 70 degrees).  However, the small streams that feed these larger rivers are still maintaining temperature.  The brooks I visited read water temperatures of 60 to 63 degrees.  Not bad considering how warm and muggy it has been the last few days.  We have been catching native brook trout on dry flies.  Mostly #12 and #14 green bodied stimulators.  Good representation of the profile of a Hopper body.  It is the time of terrestrials for fly anglers.  We did land a 12" wild rainbow yesterday while small stream fishing which was good fun on a soft 3wt. fly rod.  The brooks are teaming with brook trout. I think there was a trout  in every pool we cast to.  Afternoon rain storms yesterday brought the water up a bit, but the front that came through removed the humidity from the equation.  Off to small stream again today.  Remember to clean your gear and keep the non-native species at home.  Have fun, Willy
