In late summer, Stillwater offers clear conditions optimal for trout fishing with flows at 382 CFS and temperatures at 61.5°F. Early mornings favor caddis and midges, while afternoons shift to terrestrials like hoppers and ants. As temperatures rise, switch to heavier nymphs, and look for BWOs in the evening for optimal catches.

This week, fish the Stillwater River near Absarokee early for the best results. Key times include 6-9 AM for midge and caddis hatches, 9 AM-noon for terrestrial flies, followed by a midday break. Evening fishing resumes at dusk with hoppers and BWO hatches. Use various flies for success, but avoid the heat.

The Stillwater River is returning to cool spring conditions after a brief warm spell. Fishing improves gradually as water temperatures rise, with peak productivity typically after spring runoff.
