Dutch John, UT fishing report
The Green River below Flaming Gorge is a tailwater fishery built around rainbow trout and brown trout, both of which grow exceptionally large on the cold, food-rich flows released from the dam. Rainbows dominate the upper reaches year-round, while browns push into shallower stretches and tributary mouths in fall as spawning instincts kick in. Winter fishing stays productive because dam-regulated temperatures keep the river from freezing hard, making this a legitimate year-round destination.
Fish hold in seams where fast water meets slow, along undercut banks, and in the deep slots below riffles. Midge patterns and small San Juan Worms under an indicator account for most fish, but streamer fishing along cut banks draws aggressive takes from bigger browns, especially in low-light conditions. Watch water temperature closely — when flows spike from dam releases, fish often pull tight to structure and slow presentations outperform faster retrieves. Spring runoff concentrates trout near bottom, while late summer dropping flows push fish into faster, oxygenated riffles.
