Groundwater flooding for the Pimperne Brook

Groundwater levels in Cranborne Chase are beginning to plateau but remain high. Areas that could be affected include: Pimperne Brook at Pimperne. The groundwater level at Iwerne Hill Farm borehole is 112.03m and starting to fall steadily. A dry week apart from Thursday is expected with drier conditions returning over the weekend. Flooding of roads and some properties, especially basements is expected. Residents should continue to keep any property resilience measures such as pumps, flood barriers and air brick covers deployed. Further rainfall is forecast throughout the week which may see levels rise again. We are closely monitoring the situation. Keep up to date with groundwater levels on the 'Check for Flooding' site on gov.uk. Please take care and do not attempt to walk, cycle or drive through flood water. Never drive through flood water, just 30cm of fast flowing water is enough to move your car. This message will be updated by 12:00PM on 9th March 2026 or as the situation changes.
