It may look like water going down the drain, and that’s exactly what it is.
This is one of two bell-mouthed, 80ft stone overflows at the Ladybower reservoir in Derbyshire. They are used to drain away millions of gallons of water into the River Derwent and its tributaries when the reservoir reaches a certain level, and have been much used during the recent heavy rain. The released water even has an added bonus – it flows through turbines and creates electricity. The reservoir was formally opened by King George VI in September 1945.
