River Ash: water levels along the river

We have 5 gauges on the River Ash. 1 is below normal for the date and 1 is above. Low and high readings are fairly evenly spread.

On this page the river runs through Hertfordshire and Surrey. Reading the gauges in order shows how a rise or a dry spell travels downstream, usually over a day or more on a big river. Autumn is often a low point for rivers after the summer, until steady rain returns.
