Where
Set up a broadside drift and cover the water systematically. Fish Damsel Nymph as your primary pattern.
The plan
Plan A

Set up a broadside drift and cover the water systematically. Fish Damsel Nymph as your primary pattern.

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.

A realistic Dutch trout fallback. Do not force a wild-river-trout identity here; keep it as a stocked stillwater and lake-trout pack.

About this water

A large recreational lake near Alkmaar, popular for general coarse fishing. Trout fishing here is unproven — reports of fly-caught trout are scarce and inconsistent, so treat any account of good sport with real scepticism until you've seen the evidence yourself. For now it's better regarded as a mixed coarse water than a dedicated trout venue.
