Located in southern Oregon just north of Klamath Falls, the Williamson River measuring approximately 100 miles long, It drains about 3,000 square miles . Together with its principal tributary, the Sprague River, it provides over half the inflow to Upper Klamath Lake, the largest freshwater lake in Oregon. This nationally recognized treasure is home to the Great Basin redband trout which move to the river from Upper Klamath Lake to spawn as temperatures rise each summer. The Williamson River is famous for its trophy-size trout and rewards anglers each season with photo-worthy catch and memories to last a lifetime. With all wild rainbows often weighing in over ten pounds and the Klamath Redband Rainbows average over 20 inches. Much of the shoreline is privately with difficult wading, so fishing is done exclusively from drift boats.

Summer - Fall offers the best opportunities. The fish are primarily migratory, as the water temperatures in Upper Klamath Lake rises, the rainbows seek out the cool water sources. Of those, the Williamson River is the largest and draws the most fish.

The river boasts excellent caddis, mayfly and stone fly hatches, however due to the fact that the majority of the fish are not residents, they behave more like lake fish. Most fishing will be done sub-surface. Leeches, minnows, and nymphs are productive season long. There is a spectacular Hexagenia hatch in late June and early July.
