Upper Klamath Lake, Oregon's largest freshwater lake by surface area, offers a truly unique and often challenging angling experience. It is most celebrated for its substantial native redband trout, which can reach impressive sizes and provide powerful fights. While these large trout are the primary attraction, the lake also supports yellow perch, kokanee, and other warmwater species.

Successful angling for redband trout on Upper Klamath Lake is highly dependent on understanding its dynamic conditions. The lake is relatively shallow and can warm significantly in summer, leading trout to concentrate in cooler refuges, particularly near the mouths of spring-fed tributaries like the Williamson and Wood Rivers, and Pelican Bay. Spring, immediately after ice-out, and the fall are generally considered the best times for targeting these large trout.

Boat fishing is the most effective method for covering the lake's vast expanse and locating fish concentrations. Trolling with lures or flies that mimic the local forage, or fly fishing with sink lines and appropriate patterns, are highly recommended. Bank fishing is also possible, especially near tributary mouths, with bait proving effective at times. Conservation is paramount on Upper Klamath Lake; anglers are strongly encouraged to practice catch-and-release for most redband trout and to adhere strictly to Oregon Department of Fish & Wildlife (ODFW) regulations, which include specific slot limits and mandates for releasing tagged fish. This lake offers a formidable yet deeply rewarding pursuit for dedicated anglers.
