Lewiston Lake Fishing: Why the Trout Fishing Here Is Worth the Trip
Cold water, constant levels, and easy access make Lewiston Lake one of Northern California's best trout fisheries. Here's what to know before you cast.
Lewiston Lake doesn't get the press that bigger California reservoirs get, and that's exactly why the fishing stays good. As the afterbay below Trinity Dam, the lake runs cold and clear year-round, with stable water levels and enough trout to keep anglers coming back from Redding, Eureka, and the Bay Area.
Why the fishing is consistently good
The key is water temperature. Lewiston stays cold because Trinity Dam releases water from the bottom of the reservoir. That keeps trout active even when other lakes are warming up in July and August. The lake is also no-wake, so trolling is calm and bank access is peaceful.
Rainbow trout are the main target, with some brown trout mixed in. The California Department of Fish and Wildlife plants the lake regularly, and wild fish hold in the deeper channels near the dam.
Best seasons and times of day
Spring and fall are the most reliable seasons. March through May sees aggressive post-winter fish, and September through November offers cool mornings and less boat traffic. Summer still fishes well if you go early — the bite is usually best from dawn to about 9am.
Winter is quiet but not dead. Hardcore anglers who don't mind the cold can find fish near the inflow and outflow channels. Just watch the weather on Highway 299.
Where to fish on Lewiston Lake
The upper end near the Trinity River inflow has shallow flats that hold fish in spring. The dam end drops off fast and is where most trollers work. Bank anglers do well near the public launch and along the road-accessible shoreline early and late in the day.
A small boat or kayak is the best way to explore. The lake is long and narrow, so wind can funnel down it quickly — mornings are usually your calmest window.
Gear and tactics that work
Trolling with small spoons, Rapalas, or threaded nightcrawlers behind a flasher covers water fast. Bank fishermen do well with PowerBait, salmon eggs, or inflated nightcrawlers fished on a sliding sinker rig. Light to medium trout tackle is plenty.
If you're fly fishing, bring sinking lines in summer and intermediate lines in spring. Midges, small streamers, and damselfly nymphs are consistent producers.
Where to stay for a fishing trip
The best fishing mornings start at the resort. Our cabins give you a kitchen, real beds, and a place to rinse gear. RV sites work great for anglers with boats who want full hookups and easy launch access. Both are minutes from the best water.
We also host fishing and hiking clubs for group trips — block bookings, flexible checkout, and space to sort tackle at the end of the day.
Before you go
Check the current California fishing regulations for Trinity County, including bait restrictions and catch limits. A California fishing license is required for anyone 16 or older. If you're bringing a boat, inspect it for invasive species — Lewiston and Trinity Lakes have quagga mussel screening requirements.
