Many springs flow into Big Stoney Creek west of Edinburg and into the Hidden Valley of the Jackson. The rich green weed growth around these springs on the banks and where they flow into the streams make them easy to locate. The large populations of cress bugs and shrimp below these springs are a great source of food for the trout during the winter.
The most productive flies are Cress Bug size 14 & 16 and Murray's Shrimp size 14 & 16. I fish these upstream dead drift on a Murray's Trout Nymph Leader 9ft 5X because the built in Scientific Anglers Indicators help me to detect the strikes.
