Groundwater levels are currently rising steadily at our Stonor borehole near Henley and Assendon following rainfall over recent months. Groundwater levels are above normal and have now reached a level at which communities may be affected by groundwater flooding. We expect levels to continue rising slowly over the coming weeks and levels will remain sensitive to further sustained rainfall. Low-lying land, cellars and roads will therefore continue to be at risk of flooding.

Due to the nature of groundwater flooding, this situation could continue for several weeks or longer. We are continuing to monitor groundwater levels and will update this message next week, on 4 February 2025, or as the situation changes.
