October 2012 overview

Map of groundwater levels in the UK, Oct 2012
Groundwater levels - October 2012.
We usually expect water levels to be around their lowest in early October, but this year has been very different, and aquifers have already been well topped up by the exceptional spring and summer rainfall. The water resources situation is therefore healthier than usual for this time of year. However, going into the late autumn and winter (the time of year when groundwater recharge normally occurs) with groundwater levels that are already anomalously high means an increased likelihood of groundwater flooding in susceptible areas.

Groundwater levels are particularly high in the Chalk of the south of England were groundwater flood warnings were already issued earlier in the autumn. For more information, see the hydrological summary for October 2012 [PDF].
