Lewiston Lake - Lewiston, CA

Lake Information

Fish Species: Rainbow Trout
Lewiston Lake is a pristine coldwater reservoir located in Trinity County, renowned for its exceptional trout fishing and year-round accessibility. Fed by the Trinity River and regulated by Trinity Dam, the lake maintains cold, clear water that supports healthy populations of rainbow and brown trout.

Anglers enjoy consistent action on fish ranging from 14–20 inches, with larger specimens present. Fly fishing is highly effective, particularly with dry flies and nymphs during seasonal insect hatches. Spin anglers also succeed with small lures and bait. The lake’s upper section mimics riverine flow, while the lower half fishes more like a stillwater reservoir.

Lewiston is a no-wake zone, making it ideal for kayaks, float tubes, and small boats. Public access is available via Pine Cove Marina and multiple shoreline pullouts. Campgrounds, hiking trails, and clean facilities enhance the angling experience.

Spring and fall are prime times, though stable cold temperatures make trout fishing viable year-round. The lake is regularly stocked and carefully managed by the California Department of Fish and Wildlife.

With its tranquil setting, diverse fishing methods, and trophy-sized trout, Lewiston Lake ranks as one of Northern California’s finest year-round trout fisheries.
