Groundwater flooding in the Lower Allen Vale

Flood Warning

Groundwater levels are high and rising in response to recent and prolonged rainfall. The groundwater level at the Woodyates Borehole was 101.2 mAOD on Monday, 17/02/20. Following prolonged periods of heavy rain from Storm Dennis, groundwater levels have continued to respond. Further rainfall is expected over the next few days and we would expect to see groundwater levels rise in response. Residents are advised to prepare property resilience measures and ensure that pumps are working where they have been installed. We are continuing to monitor the situation and will update this message as the situation changes. Some borehole information can be found at https://flood-warning-information.service.gov.uk/river-and-sea-levels. This message will be updated as the situation changes.
