A handy Aberglasyln gauge.

It may have escaped your notice, but you can now ring up an EA line and get water levels for a whole shed load of North Wales rivers. All well and good, but all you get is a number, and unless you can relate that to something, it’s no use to you at all! More info on the (somewhat pricey) phone line is on the EA WEBSITE

Below is a correlation chart that I will add to in the future. I hope that this proves useful, and acts as a precursor to further river levels info.
