Lewiston Lake

B1741-800-14 Lewiston Lake

Lewiston Lake is the cold heart of the Trinity tailwater system — a long, narrow reservoir fed by water drawn from deep in the dam above, which keeps it cool and trout-rich the whole season through while lakes at the same elevation are warming and going quiet.

How to fish it · for Rainbow
When
Conditions are not ideal but fishable at Lewiston Lake. Flat calm means fish may be spookier — longer leaders and subtler flies will help.
Where
Start with Balanced Leech (8-12) on a As per local method. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. Rainbows respond to more active retrieves — try short strips between pauses.
The plan
Plan A

Start with Balanced Leech (8-12) on a As per local method. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. Rainbows respond to more active retrieves — try short strips between pauses.

Plan B

A fry-imitating pattern stripped through the margins can save a blank in autumn.

Watch for

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Bank

About this water

Lewiston Lake is the cold heart of the Trinity tailwater system — a long, narrow reservoir fed by water drawn from deep in the dam above, which keeps it cool and trout-rich the whole season through while lakes at the same elevation are warming and going quiet. That steady cold is the whole story here. It grows rainbows and browns in good condition, and because the temperature never really shuts the fishing down, it's one of the more dependable stillwaters in this part of the state. The constant flow gives it a faint river character at the upper end. Chironomids dominate the diet, and the patient indicator angler does well on them month after month. There are large browns in this water for those who'll fish a streamer through the low light and mean it. Cool, consistent, and quietly generous — a lake worth knowing.
