How to fish it · for trout
When
Late May to early June (mayfly peak); buzzer fishing March–April is the local specialist technique
Where
Set up a broadside drift and cover the water systematically. Work Spent Gnat on the bob and Shipman's Buzzer on the point.
The plan
Plan A

Set up a broadside drift and cover the water systematically. Work Spent Gnat on the bob and Shipman's Buzzer on the point.

Plan B

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.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Boat — drift

A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

About this water

Midlands limestone trout lake with a long history of holding specimen brown trout — fish here are fighters. Once compromised by pollution, the recovery has been remarkable. Mayfly hatches from mid-May are productive. The lake fishes particularly well from late April through June when olives and mayfly dominate. Excellent boat fishing when the breeze is right.
