I was up and fished last sunday morning til about 1-2. Although the waterville gauge shows higher temps don't forget that the gauge is below where little Pine flows in and empties the warm water from the reservoir. There was a good little bwo hatch in the morning which brought a good amount of fish to the surface, along with some other random mayflies, Cahill and sulphurs. After the hatch died down was hammering them on a very thickly tied white honey bug on a size 12 3x long hook, they have quite a few really nice browns in there. Although if my brother was not with me I would have been up in Slate fishing and not on the main stem.
