Winter trout tend to keep to the bottom of deep pools and become more active during midday. Fish the foot of long shallow runs. Some hatches do occur, for example midges and stoneflies. Try weighted nymphs or slow streamers. Sometimes the most effective nymph patterns imitate the largest nymph in the stream. Try sowbugs, Cressbugs, Egg patterns, Dons’ Sculpin, Crawfish & Wooley buggers.
Water temperatures in January usually remain in the low forties. We start seeing concentrations of Snowflies.
In early February water temperatures are around forty degrees.
Some hatches do occur, for example midges and stone-flies.
The first part of March brings temperatures in the mid forty's and the first Robins of the season.
