River Yarrow: water levels along the river

We have 4 gauges on the River Yarrow. 1 is below normal for the date and 1 above. Low and high readings are fairly evenly spread.

The gauges are in Lancashire. 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.
