Groundwater flooding in Finchdean, Dean Lane End and Rowlands Castle

Flood Alert

Groundwater levels at Chalton and Carpenters are high and rising, following heavy rainfall in the last 7 days. The Idsworth Lavant continues to flow. At Chalton, levels should peak in the next 24 hours. At Carpenters, it will increase over the next 12 days. The volume of water flowing through the villages will be much greater than it has been so far this winter. It will have an impact on general drainage, with more surface water affecting roads when it rains. As Carpenters peaks, levels will be very high and closer to onset of flood impacts to property. Whether more significant impacts occur, depends on whether further heavy and intense rainfall is recorded in the next 2-3 weeks. Over the next 5 days, very small amounts of rain are forecast, which won’t have much impact on levels at Chalton. We are in contact with the Flood Action Group. If you have pumps to reduce water levels, please ensure they can operate. We will update this Flood Alert by 12:00 on Thursday 27/02/2020
