Brook Road / Abbey Forgate CSO
Storm overflow run by Severn Trent Water, discharging into Rea Brook.
"Not discharging" means the company's monitor reports no discharge right now — not that the water is clean. The feed publishes status only; no discharge volume is measured.
Year by year
The Environment Agency's official annual returns, counted the EA's way (12/24-hour spills).
A spill is the EA's 12/24-hour count: the first 12 hours of a discharge count as one, each further 24 hours with discharge as one more. "Monitor" is the share of that year the monitor was working, so a 0 beside a working monitor is a real zero; "no data" means the monitor produced no usable data that year — not zero. Years before 2024 are matched to this site by name and location, because the EA's site IDs changed that year; a monitor figure beside one of them means the outlet's permit confirms the match.
Other outlets here
Severn Trent Water runs 4 other overflows within 300 m that also discharge into Rea Brook. They share the sewer and the storm, so one outlet's figures are only part of what reaches the water.
This overflow (Shrewsbury -Abbey Forgate/Brook Rd (CSO)): 1 spill in 2024. Distances are between the published outlet points. The names in brackets are Severn Trent Water's own, from its return.
Downstream of this overflow
The next gauge downstream that the river map places is Buildwas (River Severn), 33.2 km along the river.
Water-sampling points downstream
The nearest Environment Agency sampling points the river map places below Buildwas. Points between this overflow and that gauge cannot be put in order with it on the map, so they are not listed.
- River Severn the Ironbridge at Ironbridge
36 km along the river, below Buildwas · Last sampled 6 Mar 2008, before the imported period - River Severn Coalford Bridge at Coalford
37 km along the river, below Buildwas · Last sampled 20 Jan 2011, before the imported period - River Severn at Coalport
40 km along the river, below Buildwas · Last sampled 4 Mar 2024 · 2.6 years ago
A sample is dated: it is not the river now, and its results are on its own page. A sample taken after a discharge does not show that the discharge caused what was measured.

A river gauge measures the level of the river; it does not measure this overflow's discharge, and a spill does not by itself explain a change there. Traced on OS Open Rivers (edition 2026-04), which leaves out many small channels.

What the 2024 return says
From Severn Trent Water's annual return to the Environment Agency for this overflow.
"High spill threshold not met" means this overflow did not spill often enough to trigger the EA's formal high-spill review for that year. It is not a statement that the spills were harmless.
Discharges we have recorded
2 discharge periods since 8 Sep 2024. 2 of them come from Severn Trent Water's own event-duration-monitoring records (published on Stream, Sep 2024 – Sep 2024); this overflow has no live feed, so nothing after that log is held. The official annual count is the figure to quote.

The year figures above use the EA's 12/24-hour counting method, so they are comparable with the official figures.
Rain nearby last 30 days
Nearest live rain gauge: Rainfall gauge nr Shrewsbury, 2.2 km away. Brown shading = when this overflow was discharging; ▼ = a discharge start.
Overflow shading is a timing match, not proof of cause — heavy rain and spills share a trigger. Times come from the water company’s event-duration monitor (site status only; no discharge volume is published).
