How to fish it · for rainbow
When
Conditions are not ideal but fishable at Chaley Lake. Flat calm means fish may be spookier — longer leaders and subtler flies will help.
Where
Start with Booby (8-10) on a fast strip on floating line or static on sinking. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely. On a flat-calm surface, swap bushy searching dries for flush-in-film emergers — Suspender Buzzer or Shuttlecock — and fish a long leader.
The plan
Plan A

Start with Booby (8-10) on a fast strip on floating line or static on sinking. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely. On a flat-calm surface, swap bushy searching dries for flush-in-film emergers — Suspender Buzzer or Shuttlecock — and fish a long leader.

Plan B

If surface work dries up, try a diawl bach or hare's ear on the point and skate a sedge pattern on the bob at last light.

Watch for

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

Bank

Flat calm suits bank fishing near features — points, weed beds, and inflows where fish patrol.
