This past week we have been out a few times. Its winter alright, water temps are in the low 30's, so you really have to hit them in the head. Small caddis larva, and midges have been my flies of choice the past few outings. On the warmer days I have seen small pods of fingerlings up eating midges. Stick with Griffith's gnats, or small pop midges, or try to fool them with zebra midges. Even though the fishing is tough in the winter, often times you are the only one on the water, so it can be very relaxing.
