Gauging Basin
This is the outfall / overflow / spillway from Bottoms Reservoir in Tintwistle. This outfall is also the head of the river Etherow which I guess is the river that was dammed to create Bottoms Reservoir and other reservoirs in the Woodhead Valley. I’m not quite sure what all the stonework is designed to achieve but it is a tribute to Victorian design and construction.
Well, you live and learn! A quick look on Wikipedia reveals that the reservoir was obliged to release 10 million gallons of water each day for the benefit of water powered mills downstream. The circular stone construction is a gauging basin. Now I’ve just got to find out how that works.
