Even with a warmer-than-average winter, Montana’s Stillwater River is still running cold—and that’s kept fishing from fully getting going. Water levels are low, but trout have been holding in deeper slots where nymphing has produced some action for patient anglers.

Key Takeaways

• Cold water is the main limiter right now, even after a warmer-than-average winter.
• Low flows have trout set up in deeper slots.
• Nymphing has been productive for anglers willing to work for it.
• The Stillwater is typically colder than many other Montana rivers, so it often shines after runoff.
• Fishing should improve gradually as daytime highs and water temps climb.

Since the Stillwater tends to stay colder than many other Montana rivers, it usually doesn’t hit its stride until after runoff. That said, conditions should gradually improve as warmer days begin to raise water temperatures.

Latest Stillwater River Report (Montana Angler, March 6, 2026)

Here’s the latest report from Montana Angler from March 6, 2026:

Even with our warmer-than-average winter weather, the Stillwater River is still pretty cold for consistently good fishing. The Stillwater River is low, but trout are moving into the deeper slots and nymphing has been productive. This is a colder river compared to many other Montana rivers, so we typically don’t spend much time on the Stillwater until after runoff.

The Month Ahead: Fishing will be getting better and better as daytime highs and water temps gradually warm.

Long Term Fishing Forecast: The Stillwater is a relatively cold river and isn’t as productive as some other fisheries in the region until after runoff.

How to Approach the Stillwater Right Now

With low water and cold temperatures, the most consistent theme is trout holding in deeper slots. If you’re heading out, plan on a slower, more methodical day where you’re covering the most likely holding water carefully. Based on the report, nymphing has been the most productive approach for anglers willing to stay patient.

What to Expect Next (Month Ahead + Long-Term)

Looking ahead, the report points to a gradual uptick: as daytime highs rise, water temps should follow—bringing better fishing day by day. Longer term, the Stillwater’s reputation as a colder river still applies, and it’s generally more productive after runoff than it is early.
