Rainfall comes from the nearest Environment Agency rain gauge within 10 km, using 15-minute readings rolled into hourly totals. Where a gauge is further away, or too many readings are missing, we say so rather than guess. Rain figures do not show whether a discharge was permitted; that is a matter for the regulator. How we keep the record.

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.

Rain at the nearest gauge· 6.4 km away

The nearest Environment Agency rain gauge, Moreton, is 6.4 km from this overflow. It recorded 2.0 mm in the last 48 hours.

Rainfall comes from 15-minute Environment Agency readings rolled into hourly and daily totals; the 48-hour figure rests on 184 of 192 possible readings. The gauge is 6.4 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.

River level and flow nearby· 6.1 km away

Latest readings at the Environment Agency gauge "Fornalls Bridge", on the River Birket, which is 6.1 km from this overflow.

• River level0.312 h ago · falling over 24 h

These are the Environment Agency's own gauge readings at the named station, shown for context. The station measures the river, not this overflow, and a reading does not show whether a discharge occurred or was permitted. Trend compares the latest reading with the one nearest 24 hours earlier; a change of 5% or less is shown as steady. How we keep the record.
