19 gauges report along the River Colne. 9 are below normal for the date and 1 is above. Low water clearly outweighs high water at the moment.
On this page the river runs through West Yorkshire, Essex, Hertfordshire, Buckinghamshire and Greater London. 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.
