Flood alert for Groundwater flooding in the Henley and Assendon area

Get flood warnings by phone, text or email

Groundwater levels are high and continuing to rise slowly at our Stonor borehole near Henley and Assendon. Groundwater levels are above normal for this time of year and have now reached a level where communities may be affected by groundwater flooding. We expect levels to remain high for the rest of the winter period and sensitive to further 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 11/03/2025, or as the situation changes.

Flood alert area: Communities at risk of groundwater flooding including Turville, Skirmett, Stonor, Middle and Lower Assendon and parts of Henley.
