Missouri River Pelican Point Down

Please be advised of water temperatures in this lower stretch. The water temperature coming out of Holter Dam has gotten as high as 69° in the last few weeks, so the water temps below Pelican Point will be significantly higher. If you are going to fish for trout below Pelican Point, get out early in the morning and take off the river early. Keep trout in the water, opt for in-the-net pictures if necessary, and allow the fish plenty of time to recover before releasing. Remember, the health of the river starts with us!

 

If you do want to give this section a whirl, throw a grasshopper along the banks with an ant in tow, or a small Perdigon or attractor nymph 2-3 feet below. I personally would not recommend nymphing as the river is incredibly weed filled. However, if this is what you wish to do, then keep trying your favorite Zirdle bug and a Perdigon behind it.

 

Recommended Flies

Eric Paramore’s Thunderthigh’s size 8-12 in Peach, Yellow, or Tan

Kris Keller’s Henneberry Hopper size 10-12 in Yellow, Pink, or Green

Arrick Swanson’s Arrick’s Ant size 16, 18

Kelly Galloup’s Ant Acid size 14 or 16 in Black and Red or Cinnamon

George Daniel’s Gasolina Perdigon size 18, 20

Greg Garcia’s Darth Baetis in grey size 18, 20

Fred Telleen’s JZ in Tan

 

Cascade Downstream

Not much has changed here over the past month or so. When I have been chasing pike, I have stuck to the surface. Trying to elicit a topwater eat, with divers and a few poppers. I have found that using flies like Tommy Lynch’s Drunk and Disorderly, that come to the surface on the pause, and then dive back down on the strip, get eaten more successfully. Your standard popper that stays on the surface doesn’t get in the fish’s face enough to cause the kill reaction. It will work for the smaller pike but if it is the big guys your after, look no further than your local House of Fly shop or houseoffly.com for a selection of topwater pike flies.

*Be aware of Hoot Owl restrictions, from Cedar Meadows FAS down to the confluence of the Clark Fork

Get out early, get off early.  If you are fishing farther up the river, fishing will be better throughout the day. Hopper season is here for a lot of the fisheries around Great Falls, so try a big yellow Thunderthighs Hopper with a Perdigon below it. Small Chubby Chernobyl’s have been productive as well.

Clark Fork

Hoot Owl restrictions from the confluence of Warm Springs Creek and Silver Bow Creek to the river’s confluence with the Flathead River. Get out early, get off early. Hoppers, ants, and beetles will be go-to’s.

 

Creeks and Lakes

No changes here. Throwing a big hopper with an ant behind it would be the first team all American offering for me. But if you wanted a dropper, try any 16 or 18 Perdigon 2-4 feet below the hopper.

Other fisheries!

The Carp bite is on! With these warm days, the carp are up on the flats and chowing down. If you want to practice your flats stalking game, or you are just looking to catch something other than a trout, this is for you! Head down to the slow water here in Great Falls, or below any of the dams downstream and start looking. The best time of day for these fish will be from about 10 a.m. to 3 p.m. Having a high sun at your back is beneficial for sight fishing these guys. You will see them mudding, tailing, or just cruising. Try and get your fly out in front of them and then drag it into their feeding lane. If the fish is feeding well, he will key into it and make a move. From here, use long, slow strips and you should come tight to these scaley beasts.

Carp Flies:

Andrew Grillo’s Carpholio Brown or Olive size 4

Fulling Mill’s Carp Worm

FREQUENTLY ASKED QUESTIONS

Where is the best fishing on the Missouri River?
The Missouri River below Montana's Holter Dam is one of the most productive trout fisheries in the world with over 5,000 trout per mile averaging 16 inches or better. Abundant hatches throughout the season feed large groups of rising fish setting the stage for the finest fly fishing you'll ever experience. As a tailwater fishery regulated between dams, water levels and temperatures remain consistent allowing for a longer season than many other rivers in Montana. As a prime dry fly fishery, this stretch of the Missouri River is renowned for epic waters boasting large pods of fish rising rhythmically on midges, mayflies, caddis and terrestrials. The shear variety of fishing techniques that work on this river is second to none. Streamer fishing, nymphing, dry fly fishing, and skating mice all work well bringing fish to hand.
