Groundwater
Groundwater levels are high but currently stable at our Stonor borehole near Henley and Assendon as a result of recent rainfall. Groundwater levels are above normal for this time of year and have now reached a level where communities may be affected by groundwater flooding within the next few weeks. Groundwater levels remain sensitive to further rainfall due to saturated ground and high groundwater levels. Low-lying land 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 by 29/03/2024, or as the situation changes.

Groundwater
Groundwater levels are currently rising at our Stonor borehole near Henley and Assendon following recent rainfall across the area. Groundwater levels are above normal for this time of year and have now reached a level where communities may be affected by flooding from groundwater. Groundwater levels are sensitive to rainfall due to saturated ground and we expect groundwater levels will continue to rise over the coming weeks in response to recent rainfall. Basements, low-lying land and roads will therefore continue to be at risk of flooding. Due to the nature of groundwater behaviour, this situation could continue for several weeks or longer. We are continuing to monitor groundwater levels and will update this message on 22/03/2024, or as the situation changes.
