Flood Alert Info - Groundwater flooding in Flamstead

Flood Alert Currently in Force

Flood Alert issued on 25 Feb 2021 14:25
Groundwater
Groundwater levels have responded to high autumn and winter rainfall, and have risen to very high levels at our observation borehole at River Hill close to Flamstead. Groundwater levels are unusually high for this time of year and have now reached a level where communities are at risk of being affected by flooding from groundwater. We expect levels to remain high over the coming weeks in response to the high winter rainfall. Low lying land and roads such as those in the Trowley Bottom area near Flamstead will therefore be at risk of groundwater 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 Thursday 4 March or as the situation changes.
