Fishing Report Updated June 19, 2021
This Stillwater River fishing report is valid from June 18 through June.
The Stillwater River is dropping out of runoff. Fishing will steadily improve over the next week. It is likely that the best fishing on the Stillwater will occur in early July this year due to expected low flows by August.
For now, streamers and stonefly nymphs are going to be your most productive flies, though San Juan Worms will come into play as well. Bang banks and fish behind large boulders. Don’t hesitate to wade fish the heads of the big, slow pools, though most fishing will be from the moving raft. Dry-dropper and straight dry fly fishing will steadily improve over the next week or so. Fish a Chubby Chernobyl or similar dry with a compact but heavy nymph dropper.
The best fishing for right now will be above the Rosebud confluence. When the Rosebud begins to clear, the stretch of the Stillwater downstream of the Rosebud will fish well.
Our next Stillwater River fishing report will come out around July 1.
