Today’s verdict
Conditions reported — a big 31°F swing through the day.
3,870 CFS+210Flow
71°F+1°3,870 CFS is right around its typical level for July — this stretch typically runs 3,680–6,480 CFS.
Wading tends to be more manageable at typical flows, but beds shift and cold water saps strength fast — read the water, stay within your limits, and check conditions on-site. You remain responsible for your own safety.
At 71°F, the water is above the trout-stress threshold — consider resting the fish until it cools.

The Corwin Springs gauge sits right where the Yellowstone leaves the national park and enters Paradise Valley — the stretch most first-trip anglers mean by "the Yellowstone." It's a long-record station with live flow and water temperature, so the conditions here reflect the water you'll fish.

The Yellowstone is a large, free-flowing freestone river whose trout water changes from rugged canyon reaches to broad pastoral valley floats. Brown, rainbow and Yellowstone cutthroat trout are the principal targets, with mountain whitefish also common. The river is best experienced from a drift boat or raft, although public fishing-access sites and selected upper reaches provide wading opportunities. Spring fishing can be productive before snowmelt, but runoff commonly limits the river from May into late June or early July. Prime summer fishing begins as the river clears, with salmonflies, golden stones, yellow sallies, caddis and pale morning duns. Late summer adds hoppers, ants and beetles, while fall brings blue-winged olives and strong streamer fishing for aggressive brown trout. Nymphing stoneflies, caddis and mayflies is the dependable approach; dry-dropper rigs work well along banks and seams, and streamers are especially useful in stained water or cloudy weather. Because flows and clarity can change rapidly, anglers should check tributaries, gauges and local reports before launching.
