Water supply problems are not a new issue for the UK.
In the 1880s, a river in Wales was dammed to give Liverpool a desperately needed new supply. It sparked a scramble by other cities to secure their own Welsh water.
Our August river of the month: Afon Efyrnwy (Vyrnwy).

Atlantic salmon are classified as being at risk of failing to sustain their populations in all 23 of Wales’s “principal salmon rivers.”
Predictions are that they could disappear entirely from some Welsh rivers in the next 20 years.
