About Trinity River
The Trinity River below Lewiston Dam is California's top steelhead tailwater, with consistent cool flows supporting runs of both winter and summer steelhead. The Lewiston tailwater section holds wild rainbow trout year-round, while steelhead push up from the Klamath from October through April. The Hoopa Valley Tribe co-manages the fishery.
Regulations
All wild steelhead (intact adipose fin) must be released statewide. Hatchery steelhead (clipped adipose fin) may be kept — check current CDFW regulations for bag limits. California Steelhead Report Card required ($10.29) when fishing for steelhead. California Sport Fishing License required.
