Groundwater flooding in the Lambourn Valley catchment

Flood alert

Groundwater levels have responded to the recent rainfall across the area and have risen at our observation borehole in Longacre in the Lambourn Valley. Groundwater levels are higher than normal for this time of year and have now reached a level where communities may be affected within the next few days by flooding from groundwater.

The groundwater level at Longacre is higher than normal for this time of year but is currently very slowly declining. The catchment remains sensitive to rainfall due to saturated ground and groundwater levels and may start to rise again if there is further rainfall. Low-lying land, gardens, roads and cellars 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 by 15/12/2023, or as the situation changes.
