River Levels

Groundwater flooding in the Great Shefford area

Flooding possible. Be prepared.

Flood alert

High groundwater levels may lead to flooding. Flooding of low-lying areas and roads is possible.

Groundwater levels are now falling very gradually at our Northfield Farm borehole in the Great Shefford area. We expect levels to remain high over the next few weeks and levels will remain sensitive to further sustained rainfall. Due to the nature of groundwater flooding, this situation could continue for several weeks or longer.

We are closely monitoring rainfall and groundwater levels.

Residents are advised to consider property resilience measures and ensure that pumps are working where they have been installed. Take particular care when driving through flood water both for your own safety and to prevent flooding to others.

This message will be updated by 12:00 PM, on the 31 March 2026, or as the situation changes.
