Groundwater flooding in Finchdean, Dean Lane End and Rowlands Castle

Flood alert

In Finchdean, Dean Lane End and Rowlands Castle, groundwater levels are high and rising. In the last week, heavy rain (53mm) has been recorded at Walderton. Groundwater levels in Finchdean have risen by 42cm during this time. Flows in the Idsworth and Chalton Lavants are rising. We expected that a small number of properties will require water to be pumped from their cellars, and minor impact road flooding will be ongoing. Surface water may flood property during heavier rainfall events. Unsettled weather is forecast throughout the next 4 days, with up to 45mm of rain possible in Hampshire during that time. Groundwater levels throughout the valley are expected to continue rising for at least a week. More significant impacts to property, and deep road flooding are possible if heavy rain continues to affect the area in the coming weeks. We continue to monitor the levels and forecast. If you have pumps to help reduce water levels, please ensure that they are operating. This Flood Alert will be updated by 18:00 on Wednesday 06/03/2024.
