How many times did Watchet Mill Street So spill in 2025?: The 2025 return records 44 counted spill events and 29.7 hours of recorded discharge. Spills are counted with the 12/24-hour method, so this is not a count of every start signal.
Can I trust the 2025 figures for this outlet?: The monitor worked for 95.8% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Watchet Mill Street So discharging right now?: This record is linked to a company live feed. The panel above shows the latest report we hold, with its date. That report can be old, and the monitor can be offline, so check the date before relying on it. A report that no discharge is taking place is not a water-quality result.
How accurate is the map marker?: The marker comes from the grid reference in the official annual return, which is accurate to about 1 metres. It shows the recorded outlet position, not the extent of any discharge.

That is more than 84% of the 14,239 overflows in England with a reported figure, and ranks 2,078th nationally. Among Wessex Water overflows it ranks 163rd of 1,332; the median Wessex Water overflow recorded 11 spills. Ranks compare counted spill events only. They do not compare volume or harm.
Does zero spills mean the water was safe?: No. A zero means the annual return recorded zero counted spill events for this outlet and year. It is not a water-quality test, and pollution can come from other sources.
