Alert Details
The Environment Agency has issued a Flood Warning (Severity Level 2) for groundwater flooding in the Iwerne area. The alert was officially raised on March 16, 2026, in response to high groundwater levels that are expected to cause flooding impacts.
Affected Areas
The warning specifically targets Iwerne Minster within the Dorset Council region of the Wessex area.
What You Should Do
Residents in the affected area are advised to take the following precautions:
- Property Resilience: Prepare property resilience measures immediately.
- Pump Maintenance: Ensure that any installed flood pumps are functional and switched on.
- Power Backup: Consider alternative power sources for pumps in case of potential power cuts.
- Infrastructure Awareness: Be prepared for the possible inundation of septic tanks and sewer systems.
Expected Conditions
High groundwater levels are the primary hazard. Data from the Iwerne Hill Farm borehole currently records a level of 108.14m, which is reportedly falling slowly. While no rainfall is forecast for the next several days, the existing groundwater levels are high enough to cause flooding in property cellars and affect local drainage systems.
