How to fish it · for Rainbow
When
Current conditions suit Frenchman Lake well for summer tactics. The ripple should help fish move and feed more confidently. Early morning is often the most productive window in summer — make the most of it.
Where
Start with Booby (8-10) on a fast strip on floating line or static on sinking. 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. When no hatch is visible, a buzzer team — black stripped quill on the point, attractor or pearl-rib on the top dropper — is the default starting point on any UK stillwater.
The plan
Plan A

Start with Booby (8-10) on a fast strip on floating line or static on sinking. 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. When no hatch is visible, a buzzer team — black stripped quill on the point, attractor or pearl-rib on the top dropper — is the default starting point on any UK stillwater.

Plan B

Fish early and late, try deeper during the heat of the day with a fast-sinking line.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Either bank or boat

Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.

About this water

Frenchman Lake is a Plumas County reservoir out on the dry, sage-edged side of the Sierra, and it has a reputation for growing rainbows fat and strong. It's a Callibaetis lake at heart — those speckled mayflies come off the calm flats and the trout key on them, which makes for some of the most satisfying sight-fishing on stillwater you'll find anywhere this side of the crest. The rest of the time it's a chironomid game, patient and rewarding. Wind is the lake's mood-setter; learn to read it and you've half-solved the place. It fishes best in the cool shoulders of the year, with high summer warming the shallows and sending fish to the cooler depths. Don't overlook the browns holding tight to structure — they're fewer, but they're the ones you'll remember.
