The Gallatin is dropping and green. It is fishable now but still very high and tough to wade fish. If you do try the gallatin be very careful and focus on the softer inside corners and bank seams. Large stone fly nymphs with smaller attractor nymphs behind should produce good action. Large dry flies can also produce later in the afternoon and surface action should continue to improve as flows drop. Salmon flies are on the upper reaches of the river.
The Month Ahead:
The Gallatin will continue to drop each day. Once flows drop below 1500 cfs dry fly fishing should really turn on. Dry fly fishing should remain very good in the next few weeks.
Long Term Fishing Forecast:
The Gallatin should fish well all summer, mornings will produce better fishing than afternoons when temperatures rise but the evening fishing is also quite good just before dark.
