Hydrological Outlook from April 2015

Hydrological outlook map The latest Hydrological Outlook is available!

In March, normal groundwater levels were widespread across the Chalk, but with below-normal levels in north-east England and above-normal levels in the far south-east. Levels were variable in other aquifers, with both above- and below-normal levels in the Permo-Triassic of central England. 


With recessions established in most aquifers, groundwater levels over one to three months are relatively insensitive to  rainfall, with significant recharge unlikely unless rainfall is exceptional. 


The one month outlook suggests significant areas of the Chalk aquifer will see below normal levels and, except in the far south-east, the three month outlook suggests a predominance of below normal levels, with an increased probability of some notably low levels by mid-summer. Levels in the Permo-Triassic of northern England and southern Scotland are likely to remain normal or above.
