How to fish it · for Rainbow
When
Ice-off spring and autumn; summer damsel/Callibaetis
Where
Start with Callibaetis Nymph (12-16) on a slow figure-of-eight retrieve. 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 Callibaetis Nymph (12-16) on a slow figure-of-eight retrieve. 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

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

Rich Sierra reservoir up by Portola, holding chunky wild rainbows that grow fat on a diet of blood midges and damsels. This is premier stillwater nymphing — a static blood midge fished over the weed beds under an indicator is the classic Davis method, and the trick is varying your depth until you find the band the fish are sitting in. Tube and boat water. Ice-off in spring and the autumn are the prime windows, with damsel and Callibaetis fishing through the summer.
