You can expect massive redband trout in good numbers if you know what you’re doing. Though fishing is open here year-round, the redband trout found here are highly migratory, and you’re chasing fish that just aren’t in the lake consistently during the summer or winter. Fish move into the lake to feed during the spring and fall, and you can catch a dozen or more fish over 20 inches in a day.Fish average 23 to 25 inches most years, with 28-inch fish setting the standard for “trophies” and 30-inchers being every angler’s lifetime goal. The lake record was 37 inches long, and weighed more than 25 pounds. Can you break it? Most local guides offer trips in Upper Klamath and Agency Lakes, so you don’t have to fly blind. You can also launch from any of half a dozen boat launches found around the lake — all of which are free.One of the most popular areas is Rocky Point. Both the Rocky Point Resort and Harriman Springs Resort offer an array of services, including camping, cabins, restaurants, boat moorage and launching, and even canoe and kayak rentals.Upper Klamath and Agency Lakes are open year-round and allow retention of one fish over 15 inches in length, but catch and release is strongly encouraged as these fish are wild and have infinitely more sport value than food value. You can use flies, lures, or bait in either lake.
