How to fish it · for Rainbow
When
Overcast days with a light ripple, cool water; sheltered enough to fish in wind
Where
Start with Black Buzzer (10-12) on a slow, natural presentation — check locally for the preferred method. Evening can produce explosive surface takes — try a foam beetle or booby on a long leader. Rainbows respond to more active retrieves — try short strips between pauses.
The plan
Plan A

Start with Black Buzzer (10-12) on a slow, natural presentation — check locally for the preferred method. Evening can produce explosive surface takes — try a foam beetle or booby on a long leader. 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.

Bank

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
