The operator's own annual returns· 2024 to 2025

What the water company itself reported to the Environment Agency’s annual returns for this overflow, year by year. 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.

How we keep the record.

Rain at the nearest gauge· 8.6 km away

The nearest Environment Agency rain gauge, Poringland, is 8.6 km from this overflow. It recorded 6.2 mm in the last 48 hours.

Day (UTC)Rain
17 Oct 20261.8 mm
16 Oct 20264.4 mm
15 Oct 20260.0 mm
14 Oct 20260.0 mm
13 Oct 20260.0 mm
12 Oct 20260.6 mm

Rainfall comes from 15-minute Environment Agency readings rolled into hourly and daily totals; the 48-hour figure rests on 180 of 192 possible readings. The gauge is 8.6 km from this overflow, so it may not match the rain at the site itself, and the latest day may be incomplete. Rain figures do not show whether a discharge was permitted; that is a matter for the regulator. How we keep the record.
