We have 2 gauges on the River Bulbourne. 2 of them read below normal for the date, and none is running high.

The gauges are in Hertfordshire. 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.

About the River Bulbourne

The River Bulbourne is a small river in Dacorum, Hertfordshire, England. The word bourne derives from the Anglo-Saxon word for a stream. It is an unnavigable tributary of the River Gade, which flows into the River Colne, which in turn is a tributary of the River Thames. The Bulbourne is an example of a chalk stream, which is a watercourse that flows from chalk-fed groundwater. Chalk streams are a very rare habitat globally, with more than 85% of all the 210 chalk streams in the world found in England. The river is reduced in size, due to human activity, the main one being the building of the London to Birmingham Grand Union Canal through the narrow valley which takes most of the river's water.
