Castlewellan Forest Lake is one of the stronger public-estate stocked trout waters in Co. Down. Brown and rainbow trout, boat access, a central location and simple DAERA permit logic make it one of the easiest NI stillwaters to approach with confidence. It sits more in the accessible stocked-fishery lane than the wild-upland category.

The plan
Plan A
Set up a broadside drift and cover the water systematically. Work Bibio on the bob and Peeping Caddis 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
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Boat — drift
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.
