The Environment Agency and the Met Office have issued a warning about groundwater flooding in Rickmansworth, Hertfordshire, which is expected to last until at least 20 March 2026. Residents are told that water coming up through the ground could flood roads and land, making it harder to travel around the community for the next few days.
Specific flood warning zones have been identified around the River Colne, covering areas including Batchworth, Money Hill, and Maple Cross. Information from official flood monitoring services shows that these neighbourhoods are currently at the highest risk.
The risk of flooding is higher in this part of Hertfordshire because of the local chalk rock, which acts as a storage area for water. According to official guidance, these types of rocks can become saturated during wet periods, forcing water to the surface and causing long-lasting flooding on local land.
Over the next five days, people in the area might see flooding on their property, on local streets, and in some buildings. Local authorities, including Three Rivers District Council, are monitoring the situation to manage any disruption to travel or infrastructure.
Residents in high-risk areas are advised to stay alert and check for updates regularly. Officials also suggest taking extra care when moving through flooded areas, as the water can be slow-moving but deep enough to affect car journeys and walking routes.
