The Gallatin River has been fishing well with the forecast for a warm-up this weekend. This should provide even better fishing. The ice has been breaking up siring up food from the bottom. This has been providing some good fishing. The open canyon and valley stretches of waters up to Big Sky are fishing very well. The winter stones are hatching so nymphing seems to be the best. Small black stonefly nymphs are working the best. It is best to jump from one deep run to another. Look for currents that are steady enough to bring food to trout yet not too strong.
