What the water company itself reported in its annual returns for this overflow, year by year, as republished by The Rivers Trust. Hours are the total reported discharge duration; monitor working is the share of the year the event monitor was operating (a figure of 0% may mean no usable monitoring data rather than no spills). These figures are the operator's own reporting, not our measurement, and our live record above begins on 6 May 2026.

The rows carry no identifier shared with our overflow list, so each is matched by location: the nearest row within 150 m, or by permit reference where a year could not be placed. The distance is shown per row, nothing is forced, and where several rows sit at one location their figures are added together. Years where the match is uncertain, or close to another overflow's row, are left out here rather than risk showing another overflow's figures.
