Gallatin River Report
The Gallatin is a solid producer right now. The best fishing is up in the canyon. In the valley, a very early start is advised. Focus on small to medium sized terrestrials such as ants, beetles and small hoppers. When fishing slows up top, experiment with dropper nymphs 2-3 feet below the dry fly.
The Month Ahead:
Fishing will continue to improve as we move into the Fall season. Trout will become less selective with the early/late time of day activity and continue to feed later into the day. Terrestrial flies will stay important until the first big frost of the season, typically mid-September. After that, either search out pods of fish keyed in on BWOs, or strip a streamer to find that bigger predatory brown trout.
Long Term Fishing Forecast:
The Gallatin will be a good option in late summer and fall. In the fall the valley fishing improves as temperature drops. Baetis hatches in late September and October can produce some dry fly action.
