Flooding possible. Be prepared.
Groundwater levels have responded to high effective rainfall during the autumn and early winter, and have risen to high levels at our observation borehole at Lilley Bottom. Levels are unusually high for this time of year and have now reached a level where communities in the Kimpton and Lilley Bottom area are at risk of being affected by flooding from groundwater.
We expect levels to remain high over the coming months in response to the high autumn and early winter rainfall. Low lying land and roads will therefore 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 Wednesday 26th March 2025 or as the situation changes.
