- Free fishing
- Fly only
Start with Klinkhammer (14-18) on a As per local method. Midday in warm weather — switch to a fast-sink or Di-7 and fish boobies or blobs along 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.
Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.
