The giant Hex mayfly hatch is waning but a few are still around. These giant mayflies hatch around 9 p.m. Fishing should be only fair for redband trout due to past drought and there are few redband trout on public lands. Targeting brook trout near Deep Creek is another option. This area has some of the largest brook trout in the Klamath Basin.
Grasshoppers are abundant around the Old Rocky Ford Area. Fish are looking up as the Hex hatch continues. Recent reports state that few grasshopers are around. Move until you find good concentrations of hoppers.
There are incredible populations of scuds in the Williamson River. Flies that look like scuds can be productive. Brook trout are also of high quality.
Past drought from 2020- 2022 have affected adult redband trout numbers. Flows are good for fishing. Fishing on the private pay-to-fish ranches on the Sand Creek and Yamsi Ranches should be excellent for brook trout with redband trout mixed in.
