Expected Conditions
Groundwater levels at the Kingston Russell borehole are currently recorded at 119.53m. While levels are falling slowly, they remain high enough to cause significant concern. The Environment Agency reports that properties may experience flooding in cellars, and inundation of essential utility systems is likely. Additional rainfall is forecast for later in the week, which may impact the rate at which groundwater levels recede.
