The Clark Fork is still very high and is a ways out from being a realistic option. The Clark Fork up by Deer Lodge and Warm Springs are the best options if your desperate. I would look elsewhere for fishing. The Missouri, Browns Lake, Harpers Lake, Warm Springs, and Frenchtown Pond are where we would head.
HATCHES: baetis, skwalas, march browns
Other Info: The Kingfisher is the largest dealer of Simms Fishing Products in the Rocky Mountains.
