A medium reservoir in Upper Teesdale, set in the moorland above Barnard Castle with four miles of bank and a series of bays and inlets that give it more edge than a single-basin water of the same size. Fly and bait both allowed; locally farmed stock with the occasional tagged fish carrying a cash prize.
A patient day, if you fancy it

The plan
Plan A
Set up a broadside drift and cover the water systematically. Work Egg Fly on the bob and Bloodworm 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.
