UPPER WILLIAMSON RIVER: redband trout and brook troutFishing has been good. Grasshoppers are thinning out. Grasshopper dry fly patterns have been productive. Flows are very low this time of year. Hatches in poor water years are not as productive as good water years. Best bet is to pay to fish on the Yamsi or Sand Creek Ranch. Look for hatches of small mayflies such as BWOs and Mahogany Duns.Only one single point hook will be allowed beginning April 22. This change is due to record low spawning escapement for trophy redband trout throughout the Klamath Basin. ODFW also encourages the use of barbless hooks in this fishery and catch-and-release rubber nets. Last updated 9/9/21.LOWER WILLIAMSON RIVER: redband trout and brown troutNo treble hooks allowed! Very small mayflies are hatching and fish are feeding on them in certain locations. October caddis and other large caddisflies (Neophylax, Hesperophylax) are hatching as well.Open to fishing through Oct. 31. Flows are very low. Fishing is good. When fly-fishing use long, light leaders and clear fly lines for best success. Caddis flies and many small mayfly species are hatching. Flies mimicking small mayfly nymphs can work well.Regulations have changed on the Williamson River. Only one single point hook is allowed. This change is due to record low spawning escapement for trophy redband trout throughout the Klamath Basin in the spawning season of 2019-2020. ODFW also encourages the use of single barbless hooks in this fishery, not removing fish from the water and catch-and-release rubber nets. Many redband trout are starting to migrate to stage for fall spawning. Take extra care when handling these darker fish.Also, all radio tagged redband trout must be released unharmed. Redband trout will have what looks to be fishing line coming from the abdomen. These fish will be 6-18 inches long. Last updated 10/6/21.
