This is one of the most picturesque spots in Oregon’s northern Cascade Mountains because the natural rhododendron-rimmed lake perfectly reflects nearby Mount Hood.
It’s also pretty if you like trout fishing, because the Oregon Department of Fish and Wildlife stocks the lake generously beginning in May and occurring periodically throughout the summer.
Trillium is just 60 acres in size and is easily accessed from the bank or a small boat.
There is a boat ramp and a fishing dock at Trillium Lake Campground (U.S. Forest Service) on the east bank, a very nice place to spend a few days. There also is a day use area with boat launching.
Know that boat motors may not be used at Trillium Lake, but it’s a great spot for that float tube, pontoon boat, kayak or canoe.
Trillium Lake Rainbow Trout Fishing
It’s common for ODFW to plant several thousand rainbow trout here at once.
Most of those hatchery fish will be pan-sized legals, but the agency often will throw in some good-sized trophy rainbows and perhaps a couple dozen giant brood trout, so watch that rod closely because brooders can be the size of a steelhead.
The usual trout-fishing tactics will work here. Bait fishing is always effective for stocked trout, and lures and flies can produce as well. (More detail: Trout Fishing: Basic How-To Techniques and Tips.)
Fishing will be best soon after it is stocked, so use the links below for current information.
Trillium Lake Brook Trout Fishing
Anglers have reported (including on Oregon Fishing Forum) that Trillium can have pretty good brook trout fishing at times, with some mentioning that the edges of the lake’s lily pads are a good spot to find them.
Brookies are a non-native fish that reproduce naturally in many of Oregon’s high-mountain lakes and streams.
They can be caught using the same methods as the rainbows and are particularly agreeable to fly fishing.
Trillium Lake sits at 3,600 feet in elevation so there is often plenty of wintertime snow, and the lake can get off to a slower start in the spring.
Trillium Lake is located a little more than an hour and a half from Portland and about four miles from Government Camp. Two miles or so southeast of Government Camp, take Forest Service Road 2656 south to the lake.
