We follow 3,317 live gauges across the United Kingdom, spread over 51 regions. Right now 1,031 of them read below normal for the time of year, 1,199 are in their usual range and 89 are running high.
Low water clearly outweighs high water at the moment. Autumn is often a low point for rivers after the summer, until steady rain returns. The rivers with the most gauges include the River Thames, River Avon, River Great Ouse and River Derwent.
Readings come from the Environment Agency and refresh as new data is published.
