Alert Details
The Environment Agency has issued a flood alert for groundwater flooding in the Denton area. This alert, classified as severity level 3, was raised on March 6, 2026, following observations of high groundwater levels in the Solent and South Downs region.
Affected Areas
The primary area affected is Denton in East Sussex. Specific geographic impacts include local fields, the community recreation ground, and a small number of residential cellars. Motorists should be aware of flooding on Denton Road.
What You Should Do
Residents in the affected area are advised to take the following precautions:
- Exercise extreme caution when traveling on roads prone to flooding, specifically Denton Road.
- Ensure that any basement or cellar water pumps are in good working order and ready for use.
- Monitor local conditions as springs may continue to appear in the landscape.
Expected Conditions
Groundwater levels are currently high and close to the surface, showing a slow rising trend at the Houndean Bottom borehole. While springs will continue to appear, only small amounts of rainfall are forecast over the next five days. Consequently, groundwater at the borehole is expected to begin a slow decline over the coming week. Although unsettled conditions and rain may return in the second half of March, it is probable that groundwater levels will continue to fall throughout the month unless exceptional rainfall occurs.
Timeline
The alert was officially raised at 19:17 on March 6, 2026. Current forecasts suggest groundwater flood impacts may stop being visible soon as levels fall through March 10, 2026. The Environment Agency will continue to monitor the situation and has scheduled an update to this message by 18:00 on March 10, 2026.
