- Free fishing
- Fly only
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

- Local recreational charge and current Lake Akan rules apply; check zones, boat rules and any C&R requirement.
A good match for Lake Akan — most conditions are close to what it fishes best in.
