The Caterham Bourne is in flow since mid-March and is still flowing in the Whyteleafe and Kenley area, and the Environment Agency is monitoring the levels and flow of the Bourne in Kenley Bourne Park.
However, groundwater levels across the area have now started to fall, although some properties with deep basements in and around Purley and low-lying land near the Caterham Bourne could still experience flooding.
Whilst property and garden flood risks have reduced, riparian owners are reminded to keep clear any sections of river that flow through their land. The Environment Agency is monitoring the situation alongside Surrey County Council, Tandridge District Council and the London Borough of Croydon.
