Fishing in Crater Lake National Park

Crater Lake sits in the caldera of Mount Mazama in southern Oregon, a collapsed volcano that left behind one of the deepest lakes in North America.

The park's fishable water is split between that single, extraordinary lake and a network of streams cutting through the surrounding terrain — though the streams come with significant restrictions. The lake itself has no native fish.

Between 1888 and 1941, seven species were stocked; only rainbow trout and kokanee salmon established self-sustaining populations.

Kokanee are the more abundant of the two — population estimates have ranged as high as 633,000 fish — and average around 8 inches, though some reach 18.

Rainbow trout run less numerous but larger, averaging 10 to 14 inches, with documented fish pushing 26 inches and over six pounds. Both populations fluctuate year to year, so what you find on the water may differ from what you read about.

Access to the lake is a single point: the Cleetwood Cove Trail on the north rim, which drops steeply to roughly a quarter mile of rocky shoreline. Wizard Island is also fishable when the park's boat tours are running.

The lake is accessible for fishing roughly from late May through October, when the trail is clear of snow. No state fishing license is required anywhere within park boundaries.

No organic bait of any kind — including worms, eggs, or power bait — is allowed; artificial lures and flies only. Private boats, waders, and flotation devices are prohibited on the lake.

The park streams hold brook trout and brown trout, along with some rainbow. Most are steep, brushy, and hard to reach — Annie Creek and Castle Creek run through deep canyon walls.

All streams are open except Sun Creek and Lost Creek, both closed to protect bull trout, the only fish native to the park's stream system. Bull trout are federally threatened; any caught elsewhere in the park must be released.

State regulations apply to stream fishing. The fishing here is shaped as much by the place as by the fish. Getting to the water takes effort, the gear rules are strict, and the conservation context is real. That's not incidental — it's the whole deal.
