Summary for September 2014
Following the wettest August across England for 10 years, September was the second driest on record with only 22% of the long term average rainfall recorded.
Soil moisture deficits increased across England in response to the low rainfall and monthly mean river flows decreased at all but one indicator site. Despite the low rainfall, river flows were normal or higher for the time of year at the majority of sites; however, flows at approximately two-fifths of sites across northern and parts of central and southwest England were below normal or notably low.
Groundwater levels decreased at all indicator sites during September but remain normal or higher for the time of year at all sites.
Reservoir stocks decreased at all but one of the reservoirs and reservoir groups during September, but remain normal or higher for the time of year at the majority of sites. Overall reservoir storage for England was 73% of total capacity at the end of the month.
