Groundwater flooding in the Lambourn Valley catchment

Groundwater levels are high, but are falling steadily, at our Longacre borehole in the Lambourn Valley. Groundwater levels are above normal for this time of year and remain at a level where communities may be affected by groundwater flooding. This week is forecast to be predominantly dry. We expect groundwater levels to remain high over the next week, but levels are expected to continue their downward trend while drier conditions persist. Low lying land, roads and cellars will therefore continue to be at risk of flooding through this week. We are continuing to monitor groundwater levels and will update this message next week, by 08/04/2025, or as the situation changes.
