NZ8808 : River Esk
This is where Yorkshire water now draw the majority of the supply for the Esk Valley.
Previously a large volume was extracted at Esklets and Stockdale beck above Westerdale.
In dry Summers it became clear this was having an undesireable effect on the upper river as they were sometimes taking more than half the flow.
The existing pipes up the valley in many cases simply had the flow reversed.
