Groundwater is high, very close to the surface, but now falling. Springs will continue to appear, water will be in fields, small amounts of water will flow down roads, groundwater will affect the ability of the sewage network to operate in East Dean, Charlton, Singleton and West Dean, and may appear in a small number of basements. Only small amounts of rain are forecast over the five days to 10/03/2026, and groundwater at both Chilgrove and East Dean boreholes will continue to slowly fall over the coming week. There is a suggestion that unsettled conditions and periods of rain could return nex
