Cornwall's reservoir levels are now critical, both the largest (Colliford) ad the local one (Stithians) at the lowest level since the were first built.
South west water say they can pump water around, I suggest that they got on with, Roadford on Dartmoor has a good amount still. I have been told it's not that simple, and there's no means of pumping water from other reservoirs into Drift (which feeds Penzance).
Plenty of water escaping from storm sewage overflows onto beaches every time there's a sharp shower these days. Of course, they've stopped reporting overflows out of the summer season, that helps reduce the figures.
It's the same countrywide (well on the coast clearly). Back in the '90s there was great progress made, now it seems almost back to square 1. No politician gives a s**t, if they do it ends on a beach near you. Some storm overflows operate >10 times a month, in other words every time it rains.
