Latest flood alert advice from the Environment Agency: High groundwater levels may lead to flooding. Flooding is possible. Groundwater levels are falling slowly at our Longacre borehole in the Lambourne Valley. We expect levels to remain high over the next few weeks and levels will remain sensitive to further sustained rainfall. Due to the nature of groundwater flooding, this situation could continue for several weeks or longer. We are closely monitoring rainfall and groundwater levels. Residents are advised to consider property resilience measures and ensure that pumps are working where they have been installed. Take particular care when driving through flood water both for your own safety and to prevent flooding to others. This message will be updated by 12 PM, on the 7 April 2026, or as the situation changes.
