Our good friend Sam Korhel spent yesterday fishing the Irwin to Spring Creek section on the SouthFork of the Snake river. Mainly nymphing rubber legs with small dropper. The fish have seemed to be pushed up into the shallows. Streamers have been producing well on the river over the last few trips. All and all the upper river is fishing very well. If you can squeak out some time it's definitly worth wetting a line.
