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.

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

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

Calm evenings can fish well from bank or boat — target rising fish wherever you find them.
