Stillwaters: Derwent Reservoir is within five miles or so of Slaley, I think the cost was about £22 last year, fly & multibait are allowed, however the Northumberland (north east) bank is fly only. Another less busy reservoir quite close by is Waskerley, telephone 0191 488 4873 for details, fly & worm permitted. As already said, Knitsley Mill near Consett is nearby and also Witton Castle lakes, controlled by Bishop Auckland Angling Club, which is only half an hour down the A68.
Rivers: The River Derwent (which flows through the reservoir) is also very close by – Derwent Angling Association do inexpensive day tickets for the river at Allnesford and Shotley Bridge which can be bought from Frasers, Coatsworth Road, Gateshead; Allensford Caravan Park Shop and Shotley Bridge Post Office. Shotley is about 15 minutes drive from Slaley, Allensford about ten minutes straight down the A68. DAA water is fly only at that time of year. Further down the Derwent, the Axwell Park Angling Assoc.
