UPPER WILLIAMSON RIVER: Redband trout, brook trout
The Hexagenia limbata hatch should still be ongoing yet more difficult to predict. This is the largest mayfly in Oregon and emerges at around 9 pm. Large dry flies can work well during the hatch. The hatch seems to be best on very hot days. Grasshoppers are starting to show themselves as well. Hopper patterns can be productive.
The river is open year-round from the Kirk Road Bridge upstream to the Williamson River headwaters for catch and release only for Redband Trout with no bait allowed. There is no size or bag limit on Brook Trout. Conditions are good for fishing. Fishing is fair for Redband Trout and Brook Trout. Small leech patterns and wooly buggers are doing well.
