Lewiston Lake is created by Lewiston Dam on the Trinity River. It is used for trans basin diversion to the Sacramento River and flood control, as well as for hydroelectric generation.

Current Lake Conditions: Lewiston continues to offer good fishing and it should only get better as we close in on July. Once water releases out of Trinity Dam subside, the big bad rainbows will move up and concentrate near the slow currents only found above the marina. It's all rainbow trout here. Lot's of rainbows between 12"-14". Some going 18-22" also!

The Fly Shop's ? Tips: Retrieving Pheasant Tail Nymphs or something small like Mercer's Gidget has been the most productive technique lately. Go prepared with some ant patterns, just incase the carpenter ants are out. A productive technique is suspending #22 red zebra midges or Gidgets under a treated piece of poly yarn. A single BB shot will get the flies down deep. About 7-8 feet. When using indicators, the takes can be difficult to see and detect. Successful indicator anglers keep the flies in the water, sometimes letting the drift extend all the way to the backing, then low and slow retrieve. Sink tip fly lines allow anglers to retrieve leeches, buggers and small nymphs fast or slow. This lake is best fished from a motorized boat, pram or pontoon boat. Float tubes are fine if you are okay with walking back up to the parking lot after the slow current of Lewiston pushes you south of the boat ramp.

Lake Fact: Created by Lewiston Dam, Lewiston Lake is used as a diversion storage area, connected to the Lower Sacramento river via underground tunnels. Lewiston's water is used for hydro electric generation and flood control.
