Missouri River - Below Holter Dam, Montana Fly Fishing Reports & Conditions
My tips of the week
The weekend forecast is starting to look like summer! With highs the the 70s, the fish will start moving away from the deep winter runs, and move into the faster riffles and pools along the river. With this warmer weather, the water temperatures are warming up and we are starting to see more BWO activity on the cloudier days/afternoons.

Missouri, Below Holter Dam Description

One of the largest and most easily accessed rivers in Montana is the Missouri River. The mighty MO' is certainly a trout factory! Three reservoirs in a row make this tailwater fishery have a constant water flow and stable temperatures from day to day. Amazingly fertile, with prolific hatches of mayflies, caddis, and midges, the Missouri is a 365 day river. You'll see fish rising just about every day of the ...

Techniques & Tips

The classic double Nymph set up (make sure you add split shot) is the way to catch the most fish on the MO at this time of year but it's not the only way. We LOVE swinging streamers on our two-handed rods! (You can do the same with a single-handed rod as well if you haven't stepped up on bought a Switch or Trout Spey set up yet. -FYI- we can get you set up well for this fun way to fly fish!)

7-Day Forecast

Summer is right around the corner. We are still seeing thick midge hatches when the wind is calm. We are also starting to see a lot more BWO on the top, and fish are looking up. The most successful time to fish for rising fish is when we get some cloud cover, and the wind is mild. Nymph set ups have still been the most productive method on the 'Mo right now, with fire bead sow bugs being the hot fly. Baetis nymphs, such as the Green Machine, have also been working well. Open Tying every Saturday in our downtown Helena shop! Come on down, bring a vise (or demo a new one) and hang out, shoot the breeze, twist up a few flies -we'll show you some cool patterns, drink some delicious Firetower Coffee Roasters coffee and snack on sweet treats that Larry "The Urban Legend" provides! It's a good time!
