Water Situation Report
The Water Report for June makes for interesting reading. It only covers England - other countries have their own reporting bodies. We had heavy rain 180% of the long term average. River flow went up across the country. Soils became wetter through June - except in South East and South West, which continued to dry out. Groundwater levels continued to drop nationally and reservoir levels went up slightly.
Fascinating to see in London that some reservoirs are at maximum, while groundwater levels fell through June, despite all the rain. Some areas of London have "notably low" groundwater and soil deficits. Clay areas hold much better than chalk - and there are lots of both in the South East region.
