Cutthroat Trout Fishing Tips

Here are some specific fly fishing tips for each of the top locations to help you make the most out of your cutthroat trout adventure:



1. Yellowstone National Park, Wyoming/Montana

  • Fly Selection: Terrestrial patterns like grasshoppers, ants, and beetles work well in summer. At other times, small mayfly and caddis patterns are effective.

  • Fishing Tips: Target slow-moving pools and cut banks where cutthroats love to hold. Early mornings and late afternoons are often the most productive times.

  • Regulations: Always check park regulations before fishing, as some areas may be closed for conservation reasons.


2. South Fork of the Snake River, Idaho

  • Fly Selection: Dry flies like stimulators, elk hair caddis, and large stonefly patterns work great. During summer, use hopper-droppers to entice fish.

  • Fishing Tips: Look for fish near the banks, particularly during hopper season. Nymphing works well in deeper runs and riffles.

  • Techniques: Using a drift boat or a guide service can open up prime stretches of water that are hard to reach on foot.


3. Flathead River, Montana

  • Fly Selection: Streamers and large attractor dry flies such as royal stimulators or hoppers are excellent choices.

  • Fishing Tips: The North and Middle Forks of the Flathead are less pressured. Fish are often found in deep pools or near submerged structures.

  • Seasonal Advice: Fishing in the early season (June-July) can yield large fish, but be cautious of high water levels.


4. Green River, Wyoming

  • Fly Selection: Small mayfly and caddis patterns as well as larger attractor patterns work well. Stoneflies can be productive in summer.

  • Fishing Tips: Target cut banks, deep runs, and riffles. The water here is often clear, so stealth is key to avoid spooking fish.

  • Wading Advice: The riverbed can be slippery, so wear felt-bottom boots or studs for better traction.


5. Kootenai River, British Columbia, Canada

  • Fly Selection: Dry flies like Parachute Adams, elk hair caddis, and pale morning dun are staples. Try streamers for larger fish.

  • Fishing Tips: Focus on slower water and eddies where cutthroats tend to rise. The Kootenai’s fish are not as pressured, so they’re often more eager to take a fly.

  • Access: Bring a drift boat or consider hiring a local guide to access the best stretches of the river.


6. Clark Fork River, Montana

  • Fly Selection: Hopper-dropper rigs, mayflies, and stonefly nymphs are highly effective. Streamers can entice larger cutthroats.

  • Fishing Tips: During summer, look for cutthroats rising in slower water. The river’s large size can make it harder to spot fish, so target riffles and deeper pools.

  • Wading Advice: Clark Fork can be wide and deep in places, so prioritize safety when wading, especially during higher flows.


7. Coeur d’Alene River, Idaho

  • Fly Selection: Small dry flies like Adams and Purple Haze, along with terrestrials such as ants and hoppers, work wonders.

  • Fishing Tips: Cutthroat here love to rise to dry flies. Focus on pocket water and tailouts where trout like to hold.

  • Seasonal Advice: This river fishes best during summer and early fall, but make sure to stay on the lookout for runoff in early summer.


8. Snake River, Wyoming

  • Fly Selection: Terrestrial patterns are extremely popular, including hoppers, beetles, and ants. Early in the season, stoneflies and caddis work well.

  • Fishing Tips: Focus on seams and bankside structure. Snake River cutthroats often feed opportunistically and will aggressively hit well-presented flies.

  • Techniques: Float fishing is a popular method on the Snake, but wading can also be productive near riffles and slower-moving pools.


9. St. Joe River, Idaho

  • Fly Selection: Royal Wulff, Humpy, and caddis patterns work well. Don’t forget to pack some smaller attractor dries for this river.

  • Fishing Tips: Fish the head and tail ends of pools, and don’t overlook the smaller pockets of water between rapids. The cutthroats here are wild, and they readily rise to dry flies.

  • Techniques: Dry-dropper setups are often productive. Be prepared to move frequently and cover a lot of water to find the fish.


10. Blackfoot River, Montana

  • Fly Selection: Streamers, attractor dries like stimulators, and stonefly patterns are effective. Hoppers are particularly good in late summer.

  • Fishing Tips: Focus on riffles, deep runs, and shaded banks. Cutthroats in the Blackfoot often sit just below the surface, so dry flies are key here.

  • Regulations: Parts of the Blackfoot are under specific fishing regulations, so check local guidelines before fishing.


General Cutthroat Trout Fishing Tips:

  • Presentation is Key: Cutthroat trout tend to be more opportunistic feeders compared to other trout species, but a delicate and precise presentation will increase your success rate.

  • Best Time to Fish: Mornings and evenings tend to be the best times for dry fly action, while afternoons may be better for nymphing.

  • Stealth Matters: Especially in clear waters, approach quietly and avoid heavy footsteps or casting shadows over the water, as cutthroats can be easily spooked.

  • Catch and Release: Many of these rivers have wild populations of cutthroat trout, so handle fish with care and practice catch-and-release ethics to maintain healthy populations.


With the right preparation, these iconic cutthroat trout waters can provide some of the best fly fishing experiences.
