CrossCurrents Fly Shop's Tip of the Week

Some recent showers have caused the river levels to fluctuate between 3800 and 4500, which has caused some issues with the weeds, but has also kept the water temps cool. With afternoon T-storms in the forecast expect more of the same. Dry fly fishing should continue to be good with tricos in the morning and caddis in the afternoon and evening. Nymph fishing in shallow, riffly water has also been good.

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!
