The Williamson River, one of the best fly-fishing rivers in Oregon, consists of two distinct portions. The first portion is the Upper Williamson River, located above Klamath Marsh. This spring-fed system is a great place to catch redband trout and brook trout. While most of the upper portion flows through private property, you can access a little less than half of the river from the national forest roads. The second portion, known as the Lower Williamson River, is the best place to catch rainbow trout. You can also catch trophy-sized redband trout here – some as long as 20 inches. You’ll find most of the large fish in the lower portion of the river from late June through fall.
