UPPER WILLIAMSON RIVER: Redband trout and brook trout
The Hexagenia limbata hatch should be on. 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.
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 excellent for Redband Trout and Brook Trout. Small leech patterns and wooly buggers are doing well.
