Sedge evening rise expected on Thornwood Springs Trout Fishery
Good wave on — drift country. A useful wave. Work the productive shore.
The sedge is on. Buzzer may also come into play as the day warms. Drift conditions look good — cover the wind lanes. Dusk on the lake is prime time for surface feeding — stay out as long as light allows.

Today's tactical plan
The plan
Plan A · Plan B · what to watch · bank or boat
Set up a broadside drift and cover the water systematically. Work Pheasant Tail Nymph on the bob and Diawl Bach 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.
