Montana’s rivers are on the verge of waking up from their winter slumber, which means one thing for anglers: fly fishing season is almost here! As the temperatures begin to rise and the ice recedes from the banks, it’s time to start preparing for another unforgettable season on the water. Whether you're a seasoned fly fisher or just getting started, there are a few things to know before you cast your first line this spring.
When Does Fly Fishing Season Start in Montana?
While some die-hard anglers fish year-round, Montana’s prime fly fishing season truly kicks off in March and April. As the days grow longer and warmer, trout become more active, especially in tailwaters and lower-elevation rivers. The official opening of general fishing season doesn’t happen until May, but many rivers and streams remain open year-round with special regulations in place.
If you’re eager to get back on the water, late winter and early spring offer a unique opportunity. Fewer anglers, hungry fish, and stunning snow-capped mountain backdrops make for a peaceful and rewarding experience.
Where to Fish in Early Spring
Not all rivers are equally fishable in early spring, so it’s important to know where to go. Here are some of the top spots to consider:
Madison River
A year-round fishery, the Madison is an early-season favorite thanks to its consistent water temperatures from geothermal activity in Yellowstone National Park. The Upper Madison remains cold but fishable, while the Lower Madison warms up more quickly, making it ideal for early spring fishing.
Gallatin River
Located just outside of Bozeman, the Gallatin is a great option for wade fishing in the spring. The river’s clear waters and steady flow allow for excellent sight fishing opportunities before runoff season begins.
Yellowstone River
If you’re looking for big water and big fish, the Yellowstone delivers. March and April can be great for nymphing and streamer fishing before the high flows of spring runoff take over.
Missouri River
Tailwaters like the Missouri River below Holter Dam provide consistent fishing all year, but early spring can be particularly productive as fish start moving out of winter holding patterns.
Livingston’s Spring Creeks: For the Ultimate Challenge
For those seeking a true test of skill, the spring creeks in Livingston—Depuy’s, Armstrong’s, and Nelson’s—offer crystal-clear waters and highly selective trout. These fish have seen it all, earning their reputation as Ph.D.-level trout that challenge even the most experienced anglers.
While fishing these creeks requires a rod fee, early spring offers an incredible opportunity, as prices are less than half the summer rates. If you're up for the challenge, bring your finest small nymphs, midges, and light tippet, and prepare for some of the most rewarding (and humbling) fly fishing Montana has to offer.
Early-Season Fly Selection
Spring fly fishing means adapting to cold water conditions and trout that are just starting to wake up. Matching your fly selection to what’s naturally available in the river will improve your success. Here are some top choices:
- Nymphs: Midges, blue-winged olive (BWO) nymphs, and stonefly nymphs are reliable producers in the early season.
- Streamers: If you’re after larger fish, swinging a woolly bugger or sculpin pattern can trigger aggressive strikes.
- Dry Flies: While early-season dry fly action is limited, BWOs and midges can hatch on warm, overcast days, offering occasional opportunities for topwater action.
Gear & Waders: What to Bring
Spring fly fishing in Montana often means cold mornings, unpredictable weather, and the possibility of wading through icy water. Here’s what you should have in your pack:
- Layered Clothing: Waterproof outer layers, thermal base layers, and a hat/gloves will keep you comfortable.
- Waders & Boots: A solid pair of insulated waders and felt or rubber-soled wading boots with traction will help you navigate slick rocks.
- Polarized Sunglasses: These are a must for spotting fish in the water and reducing glare.
- Tippet & Leaders: Cold water often means using lighter tippets (4X-6X) and smaller flies to entice sluggish fish.
- Net & Forceps: A soft rubber net protects the fish, while forceps make releasing them quick and easy.
Regulations & Conservation: What You Need to Know
Before heading out, be sure to check Montana’s fishing regulations, as they vary by river and region. Some key points to keep in mind:
- Fishing Licenses: A Montana fishing license is required and can be purchased online or at local outfitters.
- Catch & Release: Many areas practice catch-and-release for wild trout to maintain healthy populations.
- Barbless Hooks: Some sections of rivers require barbless hooks to minimize harm to fish.
- Respect Spawning Areas: Spring means spawning season for rainbow trout. Avoid fishing in or near redds (spawning beds) to protect future populations.
Get Ready for Another Incredible Season
Spring fly fishing in Montana is a unique experience, offering solitude, stunning landscapes, and the chance to land some early-season trout before the summer crowds arrive. Whether you’re wading into the Gallatin or drifting down the Missouri, preparation is key—check your gear, study the river conditions, and have a variety of flies ready to go.
