Junk Food flies during high water
The Green River fishes excellent in May before and after high water. High water typically begins around May 15th and last 2 weeks. However, every season is different due to weather and snowpack. Some of the largest trout are caught during high water as all trout in the Green are displaced by the high flows. Being a tailwater fishery, the Green clears up relatively fast and good fishing usually resumes 2 days after the first day of high flows. Blue wing olives, trout eagerly awaiting terrestrial insects, large trout chasing streamers, and a chance at hitting the cicada hatch are all a part of the Green River in May.
