BBC - Thames Hits Highest January Flows Since Record-Keeping Began In 1883 - 2X Prior Monthly Record

The amount of water flowing through the Thames this January was the highest recorded for that month since records began in 1883.

Data from the Centre for Ecology & Hydrology (CEH) shows that the rate of water flow has now exceeded 275 cubic metres per second for more than 50 days. This is nearly twice the record duration for sustained high flow.

The CEH says that Southern Britain is likely to have the wettest winter ever recorded

Scientists from the Centre measure water flow on all the major British rivers. This winter has been a busy time for their instruments, as they have detected record-breaking rates of flow on a majority of rivers in Southern Britain.
