Understanding Hoot Owl Restrictions in Montana Fly Fishing – What You Need to Know This Season
As the summer heats up in Montana, so does the conversation around Hoot Owl restrictions—a critical topic for anglers, guides and outfitters. This early summer we have already seen warmer-than-average temperatures and lower river flows, and based on current trends, we’re expecting more Hoot Owl restrictions to roll out across Montana by the end of summer.
Whether you’re a visiting angler or a local, understanding the truths, rumors, and myths surrounding these restrictions is essential—not just for staying legal, but for protecting the fishery for seasons to come.
What Are Hoot Owl Restrictions?
Hoot Owl restrictions are mandatory fishing closures set by Montana Fish, Wildlife & Parks (FWP) that limit fishing during the hottest part of the day, typically from 2 p.m. to midnight. These closures aim to protect cold-water fish species—especially trout—during times of stressful water temperatures, often when water temps hit or exceed 73°F for three consecutive days.
Why Are They Happening?
In 2025, we’re already seeing:
Unseasonably warm weather
Low snowpack and early runoff
Lower-than-normal streamflows
These conditions lead to higher water temps, which put serious stress on fish populations. Trout, especially, have a narrow temperature range in which they can survive and thrive. Fishing during high-temp periods can increase mortality, even with catch and release.
Myths, Rumors, and Realities
Myth: “If it’s legal, it’s ethical.”
Truth: Just because you can fish legally doesn’t always mean you should. For example, the Lower Madison River, though open, experiences bathwater temps by midday during summer. Even though its legal to fish it during the allowed hoot owl times, we recommend avoiding it altogether during peak heat.
Rumor: “All rivers are closed during Hoot Owl.”
Truth: Hoot Owl restrictions are not statewide blanket closures—they apply river-by-river and are based on real-time temperature data collected by Montana FWP. Many of our Rivers often stay cool enough to remain open. These spots can still offer great fishing opportunities—as long as you get out early in the day and monitor conditions regularly.
Myth: “If a river is on Hoot Owl, it means the whole river is closed.”
Truth: Just like Hoot Owl restrictions vary river by river, they also often vary by stretch. A river may have Hoot Owl restrictions only on lower or midsections, while upper elevations remain open and safe to fish. This is especially true for rivers fed by dams or cold mountain tributaries. Always check the Montana FWP website to see if the closure applies to the entire river or just certain sections.
How to Fish Responsibly During Hoot Owl
Fish early: Hit the water at dawn and be off by noon or earlier.
Use heavier tippet and barbless hooks for faster landings and easier releases.
Prioritize cold-water tributaries and high-elevation creeks.
Check the FWP website daily for updated Hoot Owl restrictions across Montana.
Avoid the sections of rivers that are warmer even if they are open
A Word from Rising Trout
At Rising Trout Fly Fishing Outfitters, we’re committed to ethical fishing practices and the long-term health of Montana’s rivers. Our guides are trained to adapt trips based on current conditions—targeting the cooler stretches and ensuring early start times. We always put the fish first, even if that means adjusting where, when or how we fish.
And remember, Montana is a big state with a lot of water—and not all of it is under restriction. With the right planning and local insight, you can still have incredible days on the water, catch beautiful trout, and do it all responsibly.
If you're planning a trip or have questions about current restrictions, reach out to us or check the FWP site regularly. Let’s work together to protect what we love.
