Recent rain welcome but groundwater sources remain slightly below average
We welcomed the rain in late September in our East region, which was above the long-average at 116%.
However, groundwater levels are still slightly below average following a prolonged period of dry weather and a few good weeks of rain is not enough to make up for this. We are now entering the important recharge season when we typically see recharge of groundwater, if there is sufficient winter rainfall. This period usually runs from October to March.
Soils in our East region have been drier than average, so any rain that falls now will first be absorbed by the soil before it filters down to the aquifer (porous rock where groundwater is stored), potentially delaying recharge of groundwater.
You may have heard that our central region (covering north London and parts of Bedfordshire, Hertfordshire, Buckinghamshire and Surrey) is in drought following three years of below average rainfall. Whilst groundwater levels are below average in your region, they are in a better position than our central area and have not yet reached the level where we would have to declare a drought.
Whatever the weather brings, it is important we all continue to think about our water use.
