- Free fishing
- Fly only
Start with Foam Beetle (14-18) on a As per local method. 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.
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.
Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.
