Plug?

Some sort of mechanism to regulate the waterflow from Rivington Reservoir I presume. Gorgeous morning to be out, felt almost spring-like. Enjoyed a fairly leisurely run from Rivington out to Healey Nab looking for the heronry en route. Down to White Coppice and then over Great Hill in the opposite direction to last Saturday's event - out to Round Loaf and back. Probably no more than twelve miles (Garmin packed in) don't have exact mileage - half last Saturday's distance! Legs still a bit tired, but great to be out - Lakes tomorrow : )
