How To Fish It

  • Fish long drifts through weed lanes and the soft edges of deeper buckets with small flies and enough weight to stay in the lower half of the column.
  • Target seam lines off grass beds, transition shelves, and quiet slicks below riffle tongues.
  • When fish begin rising consistently, switch to a BWO or midge dry only after you have the right lane and angle. Green fish punish drag quickly.

Today's Feeding Pattern

Green River trout feed steadily in late April, but they are usually tuned to smaller food and cleaner drifts than visitors expect. Fish hold in weed lanes, bucket seams, and broad flats where scuds and sowbugs wash naturally. When BWOs come off, the better fish often rise in the gentler slick water, but subsurface presentations still account for most of the day's trout.

About The Green River

The Green below Flaming Gorge Dam is one of the West's signature tailwaters, known for clear water, strong bug life, and high trout density. The river is split into recognizable sections, but the core pattern is the same: technical presentations in stable holding water.

Rainbows and browns are the primary quarry. Anglers know the river for productive nymphing, selective dry-fly fishing, and trout that feed heavily on small invertebrates year-round.
