Alert Details
The Environment Agency has issued a flood alert for the River Thames and its small tributaries from Calcutt to Lechlade. This alert was officially raised on March 2, 2026, at 9:01 AM following observations of high river levels across the region.
Affected Areas
The alert covers a significant stretch of the River Thames and several associated waterways, including Blunsdon Brook, Water Eaton Brook, Marston Meysey Brook, Share Ditch, Bydemill Brook, Westrop Brook, and Downington Brook. Geographically, the impact zone spans Gloucestershire, Oxfordshire, Swindon, and Wiltshire. Specific concern has been noted for the Hannington Wick area, where flooding of low-lying land and roads is expected to continue throughout the day.
What You Should Do
Residents and travelers in the affected regions are advised to avoid using low-lying footpaths and roads near rivers, as these areas may be submerged. The Environment Agency recommends monitoring current river levels through the River Levels Online service for real-time updates and staying prepared for potential travel disruptions.
Expected Conditions
High river levels are currently impacting the River Thames and its tributaries. While flooding of roads and land is ongoing, the immediate forecast predicts a dry day today, March 2, with dry conditions expected to persist for the next several days. Consequently, authorities expect river levels to begin decreasing over the coming days.
Timeline
The alert is currently in effect as of March 2, 2026. While the situation is expected to improve as water levels recede during the upcoming dry spell, the Environment Agency plans to provide an updated message by 12:00 PM on March 3, 2026, or sooner if conditions change significantly.
