Welsh Water operates the reservoirs across Wales to ensure that we can meet our customer demand, whilst respecting the environment in which we live. To do this, we continuously monitor the levels of our reservoirs to ensure we are operating in an optimal manner.

Every week, we will publish an updated water situation report for major supply reservoirs across Wales. We also provide this report to the Environment Agency Wales and the Welsh Assembly Government. As well as current storage levels and monthly average rainfall, this report shows how current levels compare with this time last year and with 1995, the most recent drought period, which affected many parts of the UK.
