Today’s verdict
Conditions reported — a big 32°F swing through the day.
3,530 CFS is on the low side for July — this stretch typically runs 3,560–5,200 CFS.
With flows lower than usual, wading is generally easier and more forgiving — but beds still shift and cold water saps strength fast, so read the water, stay within your limits, and check conditions on-site. You remain responsible for your own safety.
At 68°F, the water is warming toward the trout-stress zone — fish early and handle any fish quickly.

The gauge below Holter Dam sits at the head of the Craig tailwater — the technical dry-fly water with famous PMD and trico hatches that anglers from Helena and Great Falls target. It carries both flow and water temperature, so the read reflects the section you'll fish, not the reservoirs upstream.

The Missouri below Holter Dam near Craig is a broad, productive tailwater renowned for high trout numbers and highly technical dry-fly fishing. Rainbow trout dominate, with brown trout also common. Its long flats, riffles, weed beds and deep runs are best covered by drift boat, although numerous fishing-access sites provide good walk-and-wade opportunities. Stable cold water supports year-round fishing. Midges and blue-winged olives drive winter and spring fishing, followed by caddis and PMDs in late spring and summer. Tricos become important in midsummer, with terrestrials and October caddis adding seasonal variety. Sight-fishing small dries to selective trout is the river’s signature experience, but short-leash nymphing over shallow flats and deeper indicator rigs remain more consistent. Sowbugs, scuds, worms, mayfly nymphs and caddis pupae are staples. Streamers can produce during cloudy weather and seasonal transitions. The river can become busy during prime hatches, and wind is a defining challenge, so early starts, late shifts and accurate presentations are useful.
