A week of much-needed rain greened things up, and the Missouri is squarely in prime time. PMDs are the headline act in full peak about a month into their run, caddis have arrived in numbers driving strong evening dry-fly action, and the Dearborn has bumped back to life. Crowds are heavy, so go early or go late.

The Mo is fishing well across all reaches, with flows settling back near 3,400 CFS after a rain bump and a green tint downstream from the Dearborn. It is prime time: the PMD hatch is a few weeks early and in full swing, with caddis building. Craig and the ramps are busy, so plan around the crowd.

The unseasonably cool, wet pattern that closed out May is still running the show, with the Mo bumped over 3,500 CFS and now dropping back near 3,400. PMDs are well underway, and the cool weather has the shops optimistic the early start means bonus time rather than an early end. Early terrestrial fishing is paying off on the right day.

Early summer has arrived ahead of schedule, with the river holding in the 3K club and acting more like a freestone in this low-water year. PMDs are in their historical main-event window right now, caddis are building, and the fish are eating heavily but getting educated daily. A soaking late-May rain added a touch of color.

Summer conditions are arriving fast and the river is fishing more like a freestone, warming through the day as water moves down from the dam. A warming trend is pushing caddis along while the PMD dry-fly windows open but stay technical. Fish are in their peak metabolic window and eating heavily every day.

The Missouri is acting more like a freestone than a tailwater, with low water driving pronounced daytime warming the further you get from the dam. PMDs are on in numbers, caddis are building, and trout are in their peak metabolic window but increasingly educated. Near-term weather is split between a wet front and a warm-up.
