Idaho Fish Report

UPPER WILLIAMSON RIVER:

Fishing should be excellent with the black drake mayflies hatching. Flows are at 55 cfs. The river is slightly offcolor. The best method is to look for rising trout to black drake mayfly spinners.The lower section of the Williamson River near Old Rocky Ford is best fishing. .

LOWER WILLIAMSON RIVER:

Opened on Monday, May 22. The river is fishable at 909 cfs. Numerous hatches of mayflies, stoneflies and caddisflies are hatching. Currently, small mayflies are the best insect to match. A size 16 pheasant tail matches this hatch well. A few suckers might still be spawning and sucker egg patterns can be excellent. Some very large bright redband trout are entering the river thus larger leech and streamer patterns can catch these. Please remember no treble hooks or bait allowed on the river. Most fly anglers use a clear intermediate fly line on 6 to 8 pound fluorocarbon leaders and swing fly patterns deep.

Areas above Chiloquin will be crystal clear, very cold water. Fishing is always very challenging in this stretch.
