LOWER WILLIAMSON RIVER:

Fishing has been very slow and inconsistent this year. Flows are low. Redband Trout have moved in from Upper Klamath and Agency Lake as well as the Link River, Lake Ewauna and Klamath River.

The large Hex mayfly is hatching with the best areas below highway 97 and below Modoc Point Road. These are the largest mayfly in Oregon and hatch at dark. Trico mayflies are also hatching.

Most flyfisherman use a clear intermediate fly line, long fluorocarbon 4-6 pound leaders and swing small bead headed flashback pheasant tails or prince nymphs. Fish are wary therfore consider going with smaller lures and flies. No bait allowed and only single point hook is allowed.

Most of the catch is 8 to 14 inch Redband Trout but bigger Redband Trout are around.

UPPER WILLIAMSON RIVER:

Flows are perfect for fishing. The water is off color at Old Rocky Ford.

Dry fly fishing is fair for brook trout near the Deep Creek confluence. Best fishing for Redband Trout is below the old Rocky Ford crossing.

Grasshoppers are also around and flyfishing should be fair.

Sand Creek and Yamsi Ranches offer exceptional pay to fish operations.

Check Upper Williamson River Flows.
