March 2014 overview

Groundwater levels, March 2014
March was unusually typical! After several months of exceptional rainfall, rainfall totals for March were within the normal range at the national scale. Rainfall was, however, below average over swathes of England and Wales, north-eastern Scotland and parts of Northern Ireland.

The groundwater recharge season has ended in many lowland areas, with hydrographs showing falling levels.  However, levels in the index wells remain within or above the normal range for the time of year.

Areas impacted by groundwater flooding are diminishing, however, it remains an issue in some areas, such as parts of Berkshire, south London, north Hampshire and Oxfordshire.

Record monthly maximum levels were recorded in Skirwith and Newbridge boreholes (Permo-Triassic sandstones of north west England and south west Scotland) for the third successive month, though levels did peak during March.
