Groundwater flooding in the Henley and Assendon area

Groundwater levels remain high at our Stonor borehole near Henley and Assendon. Groundwater levels are above normal for this time of year and remain at a level at which communities may be affected by groundwater flooding. This week is forecast to be predominantly dry. We expect groundwater levels to remain high for the next few weeks and levels are sensitive to sustained periods of rainfall. Low lying land, roads and properties will therefore continue to be at risk of flooding. We are continuing to monitor groundwater levels and will update this message next week, by 08/04/2025, or as the situation changes.
