fishing the cold water

Hi Folks, Spent a fun afternoon fihsing the Lamoille with firends that I work with at the Stowe Mountain Resort in the winter.  I was fly fishing and they were using the spin gear.  Water temperature was 43 degrees at 3:00pm and the level was slightly above the seasonal average.  Cloudy and over cast yesterday with a very sparse hatch of #20 BWOs.  We fished large primary pools with stability and even spots were trout will hold for the winter.  Slower water versus the fast riffles was were found trout.  Landed 6 trout yesterday with 5 being wild fish and 1 being a stocked rainbow.  The fish of the day was a 16" wild female brown trout with  beautiful spawning colors.  She was pretty fat and probably still holding eggs.  The fly of the day was a #10 tungsten prince nymph and the lure of th day was a yellow rooster tail.  Pretty good fishing considering the water temperatures.  Looks the rest of the season could be cold fishing as there is no warming trend in the near future.  Remember to clean your gear and keep the non-native species at home. 
Have Fun, Willy
