The Jubilee Flood Relief Channel: your questions answered

  • Jubilee operational status

    supporting image

    We are not currently operating the Jubilee as a Flood Relief Channel, but it remains ready to be used to reduce the risk of flooding for the Maidenhead, Windsor and Eton areas when required.

    Our specialist officers constantly monitor the river and in flood conditions we split some of the water from the River Thames into the Jubilee.

    We are not able to tell people directly every time we increase or decrease the flow of water through the Jubilee. Our duty officers don’t have the resource to be able to offer this service. This is because our team prioritises issuing flood alerts and flood warnings over a large geographical area. This work is time critical, requiring 24/7 observation of river levels and flows and needs quick decisions to ensure people are warned and informed in an accurate and timely way.
