Lower Madison River Fly Fishing in April
April marks the start of spring fishing on the famed Lower Madison River in Montana. This picturesque tailwater, which flows out of the Madison Dam below Ennis Lake, boasts thriving populations of rainbow, brown, and westslope cutthroat trout.
As air and water temperatures rise, anglers enjoy excellent dry fly, nymph, and streamer fishing between Beartrap Canyon and the river’s mouth near Three Forks, Montana.
Lower Madison River Fly Fishing Hatches in April
The Mother's Day caddis begin to appear in late April and continue well into May. This important Southwest Montana hatch gets significant attention from both trout and fly anglers. The first major emergence of the season, this hatch brings fish of all sizes to the surface between Beartrap Canyon and Greycliff Fishing Access Site.
Though less prolific and dramatic, other early season hatches include blue-winged olives (BWOs), midges, and March browns. These can also provide excellent “match the hatch” dry fly fishing opportunities on calm, cloudy days through late April.
Although typically sporadic and sparse, Skwala hatches are common in Beartrap Canyon throughout March and early April.
Lower Madison River Fly Fishing Techniques in April
To catch rising trout, use stealthy approaches and accurate casting along river banks and seams. Look for mayfly and midge hatches on cloudy days between Warm Springs and Black's Ford Fishing Access Sites.
Use large Skwala imitations trailed with small dropper nymphs in the pocket water of Beartrap Canyon.
When hatches are sparse, or fish aren’t rising, drift tandem nymph rigs. A crayfish imitation followed by a small mayfly nymph or egg pattern often works. During the late April Mother's Day caddis hatch, use small olive or tan caddis dries and caddis emergers to target rising trout.
Bozeman Fly Fishing Guide Pro-Tip:
Rainbow trout spawn in March and April on the Lower Madison, so be mindful of wading over areas with "clean" gravel. Nymph fishing the deeper runs with a variety of egg patterns is effective in April in the Beartrap Canyon. Our guides fish a pink CDC baetis emerger pattern as a dropper behind a Clouser Crayfish, under a strike indicator in early April on sunny days.
