Groundwater flooding in Vernham Dean, Upton and the Bourne Valley

Groundwater levels in the Bourne Valley remain high. At the borehole in Vernham Dean, the level has fallen by 1.08m. At Upton, the level remains relatively steady. Flooding is expected to be affecting a small number of cellars in Upton. Septic tanks will also struggle to operate properly. Currently, we do not expect significant impacts to property at Vernham Dean, Hurstbourne Tarrant, Stoke or St Mary Bourne. Mostly dry weather is forecast on Tuesday 10/03/2026, Wednesday 11/03/2026 and Saturday 14/03/2026. On Thursday 12/03/2026 and Friday 13/03/2026, further rain (between 20 and 25mm) is expected. This rainfall is likely to prolong ongoing groundwater flooding impacts. We are closely monitoring the situation. Residents are advised to prepare property resilience measures and ensure that pumps are working where they have been installed, especially if you are in Upton.
