Live levels from 3 monitoring stations across Warrington, updated every 15 minutes.
| Station | Level now | Status | ||
|---|---|---|---|---|
| Causey Bridge | 0.24 m 29m ago | Normal | ||
| 2.9 km by river | ||||
| Higham Avenue | 0.34 m 29m ago | Normal | ||
| 3.2 km by river | ||||
| Liverpool Roadtidal | 1.48 m 29m ago | Normal | ||
Stations are listed from source to mouth as the water flows, traced on the river map (OS Open Rivers) and the Environment Agency’s own links between its gauges. A distance “by river” is along the river, and is shown only where the map traces the path.

Streams and rivers with a gauge whose water joins Sankey Brook above one of its gauges, from the source down. Named streams without a gauge that have a page here are listed at the end.
Joins Sankey Brook above Causey Bridge, its highest gauge, no more than 10.6 km by river above Causey Bridge.
| Ivy Street, Ashton-In-Makerfield | 0.21 m 2d ago | old reading |
| 1.0 km by river | ||
| Lincoln Drive | 0.25 m 29m ago | Normal |
Its water passes every gauge on Sankey Brook, from Causey Bridge down.
Joins Sankey Brook above Causey Bridge, its highest gauge, no more than 11.7 km by river above Causey Bridge.
| Ellamsbridge Road, St Helens | 0.06 m 29m ago | Low |
Its water passes every gauge on Sankey Brook, from Causey Bridge down.
Below Liverpool Road, its water next reaches Fiddlers Ferry, a gauge on River Mersey, 3.1 km by river downstream.
Tributaries and where they join are traced on the river map (OS Open Rivers, edition 2026-04) and the Environment Agency’s links between its gauges. The map holds distances between gauges, not the junctions themselves, so a junction is placed between two gauges, and no further up than the tributary’s own lowest gauge. Contains OS data © Crown copyright and database rights 2026.
29 storm overflows are traced upstream of Liverpool Road, Sankey Brook’s lowest gauge on the river map: on Sankey Brook itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Liverpool Road: 477 spills over 2,082 hours in total, across all 29.
Each overflow is listed in the stretch above the first gauge its water reaches, from the source down, as on the Gauges tab. A stretch of Sankey Brook includes the smaller streams that join it there.
Within 3 km of one of Sankey Brook’s gauges in a straight line, but the river map cannot say whether their water reaches it.
5 more near these gauges whose connection is not known.
3 other overflows within 3 km of these gauges are placed below Sankey Brook’s lowest gauge or on another river, so not listed.
A status is the water company’s own monitor: it says whether an overflow is discharging, never how much or why, and a spill does not by itself explain a change in a river level. A status older than two hours is shown as unknown. Annual figures are the official returns: 12/24-hour spills for England and Wales, overflow events for Scotland (Scottish Water counts differently, so the two cannot be compared). “No data” means the monitor produced no usable data that year, not zero. Overflows are placed on OS Open Rivers (edition 2026-04), which leaves out many small channels: an overflow the map cannot place may still drain here.

Dated samples taken by the Environment Agency, not live readings. Results are published days to months after the sample is taken, and many points are sampled only a few times a year, or have not been sampled for years.
24 sampling points on the Sankey Brook and the streams that join it above Liverpool Road. 4 have a sample from the last 12 months; 7 have any sample banked. Listed from the source down, grouped by the next gauge each one's water reaches.

Distances are along the river to the gauge named. England's samples only.
FloodRadar does not grade these results: there is no overall score, and official river classifications are a separate dataset. A sample taken downstream of an overflow does not by itself show where anything in it came from. River connections and distances are traced on OS Open Rivers (edition 2026-04), which leaves out many small channels.
