B Section

The B Section of the Green River tailwater extends downstream from Little Hole and maintains excellent trout populations. Brown trout dominate this section with fish averaging slightly larger than the A Section. Evening pale morning dun and caddis hatches produce outstanding dry fly action from June through September.

💧 Ideal flow: 1,000–2,500 CFS. The B Section fishes best at moderate flows — a mix of wade and float fishing through the red rock canyon.

C Section

The most remote section of the Green River tailwater the C Section requires a float from Little Hole or a long hike. Wild brown trout here see less fishing pressure and are more willing than fish in the A and B sections. The canyon scenery in this stretch is the most dramatic on the entire river.

💧 Ideal flow: 1,500–3,000 CFS. The C Section is broader and best floated at moderate flows — large browns hold in the deep runs.
