Chalk streams remain dry despite wetter weather

The unique chalk streams to the north of London continue to be dry, even though November brought more rain than usual, according to Environment Agency data.

According to the agency’s latest monthly situation report for Hertfordshire and North London, the area received 121% of long-term average rainfall in November, or 138% over October-November.

In response, river flows and groundwater levels at the majority of monitoring sites in the Upper Lee and Colne catchments increased and “soil moisture deficits across the area were erased”, according to the report.

“Despite this, many remained with below normal flows,” it continues. Over the last 12 months, rainfall across the area has been somewhat less than normal, at 89-97% of the long-term average.
