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:
What can we say? There's some big ol' rainbows in Lewiston! We expect the quality of fishing on Lewiston to improve through the next few months. As the days get warmer and warmer, the carpenter ants will show up and produce a new dimension to the Lewiston angling experience.

The Fly Shop's ? Tips:
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.
