CrossCurrents Fly Shop's Tip of the Week

Late Winter - With the warmer temperatures we have had this week the fish are most active and willing to eat. The main food source for trout at the moment is still sowbug and midges. The main negative factor will be the wind, we have had a couple days with high gusts up to 35mph.

5-Day Outlook as of 2/27/26

After a cold couple weeks, we are starting to see higher temperatures and less snow. The main factors effecting fishing conditions right now are temperature, cloud cover, and wind. The ideal day would have air temperatures in the 40s, partial cloud cover, and minimal wind.

Techniques & Tips as of 2/27/26

The two suggested techniques right now would be swinging smaller streamers or nymphing sowbug and midge patterns. If you are fishing from a boat I would recommend nymphing any hothead sowbug (size 16) to a red or black zebra midge (size 18) about six feet down. Throwing some split shot on the will make the rig more efficient. If you are wade fishing, I would reccomend swinging streamers through some good looking riffles. I would suggest a 4-6 IPS polyleader/sinktip to get the streamer into the right water column. We have seen far more success on smaller sized streamers. Somewhere between size 6-10. We have seen few rises for midges and when we do they are 1. not consistent and 2. not rising in pods which makes presently a dry fly nearly impossible.

Description: About Missouri River

The Missouri River is one of the largest and most easily accessed rivers in Montana. 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 year. Take a float trip down the Missouri and you'll know why it made such a powerful impression on Lewis and Clark during their great expedition. During the summer, caddis and mayfly hatches are so prolific that it looks as though there is a mini blizzard over the river. This river is known for its excellent dry fly fishing. But it's also amazing when fished with emergers. or small bead-heads as a dropper behind a dry fly. The MO fishes fantastically in the shoulder seasons of Spring and Fall with Baetis and Midges for dries and big, ugly streamers! That is when some very big fish are caught! The Missouri throws itself into the heated debate of "Row vs. Wade" because it is so perfectly suited to angle from both a drift boat (or other water craft) as well as wade fishing on foot. With an adult trout population (Rainbows and Browns over 10") between 4000-8000 fish per mile and an average size of 16"-18", it's not too hard to figure out why the Missouri ranks up there with many people's favorite places to fish!
