CrossCurrents Fly Shop's Tip of the Week

Spring fishing season has arrived, bringing with it rain showers and BWOs. Look for an overcast day and there should be a good hatch of BWOs with rising fish on them. Our town bridge is currently under construction for 2-3 weeks, meaning the highway is the only way in and out o town. This construction had made river access and running shuttles a little tricky so plan ahead.

5-Day Outlook as of 4/18/26

It seems we have fully transitioned into spring here in Craig. Temperature will be moving around this week with the highs being in the 70s early in the week before dropping into the. 40s towards the end. The wind is being a bit temperamental, with some days being windy and the next being calm, so definitely watch the forecast for a calm day.

Techniques & Tips as of 4/18/26

The two suggested techniques right now would be swinging smaller streamers or nymphing sowbug, baetis and midge patterns. If you are fishing from a boat I would recommend nymphing any hothead sowbug (size 16) to a BWO nymph (size 18) about six feet down. A zebra midge (size 18) is also a good option for that second bug. Throwing some split shot on the will make the rig more efficient. If you are wade fishing, I would recommend 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. Dry fly fishing is definitely a thing now. Good size hatches of midges most day with BWOs coming out in the evenings. The fish are little tricky so smaller flies will be the ticket. Try tying a Griffith's Gnat as sighter and dropping a BWO off the back of it.

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!
