Reservoir levels

Here you can view up-to-date information on the water levels in our reservoirs at Bewl Water, Darwell, Powdermill and Weir Wood.

Our reservoirs

Only about 7% of the water we supply comes from reservoirs overall but they're still vital for the supply of water to certain areas in our region.

Below, you can view the current levels compared to average and minimum levels. During the winter we expect a fairly rapid refill due to wetter weather, but this isn’t always the case. The reservoir levels can vary widely year on year depending on the weather, transfers to other water companies or any operational issues that have happened.

On the graphs below, the blue line represents the long-term average levels, the green shows the minimum levels and the purple shows the most recent actual levels.

We aim to update these figures every week.
