Steelhead usually arrive to the area in October and are usually in the system until February. Klamath River steelhead run to about 8 pounds with most fish being in the 4 - 5 pound class. The numbers of fish caught are absolutely incredible with 10 fish per rod days not uncommon.
In September, the King Salmon arrive to spawn. The fish, stack in the deep holes before heading to the spawning beds. The action is intense with hook-up after hook-up. The average fish is about 15 pounds, with the occasional larger hog being landed.
There are places where larger trout, steelhead, and Chinook can be caught. However, few places can rival the high quality non-stop action of the Upper Klamath whatever species you target!
