Reservoir levels

Current reservoir levels are shown below and are updated once a week. The date shows the week ending (always a Sunday) of when the readings were taken. We try to put them here by the following Wednesday, but it can take a little bit longer if there has been a bank holiday.  Please note we provide these to give a snapshot of the previous week’s storage in our reservoirs. The Environment Agency website provides current river levels, flood warning and flood risk forecasts, and should be referred to when assessing potential flooding.
