Live levels from 2 monitoring stations across South Yorkshire, updated every 15 minutes.
| Station | Level now | Status | ||

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 Blackburn 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 Blackburn Brook above Sheffield Blackburn, its highest gauge, no more than 7.0 km by river above Sheffield Blackburn.
| High Green | -0.01 m 1h ago | Low |
Its water passes every gauge on Blackburn Brook, from Sheffield Blackburn down.
Joins Blackburn Brook above Sheffield Blackburn, its highest gauge, no more than 3.2 km by river above Sheffield Blackburn.
| Ecclesfield Morrisons | -0.05 m 1h ago | Low |
Its water passes every gauge on Blackburn Brook, from Sheffield Blackburn down.
Below Sheffield Wincobank, its water next reaches Rotherham, a gauge on River Don, 5.6 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.

14 storm overflows are traced upstream of Sheffield Wincobank, Blackburn Brook’s lowest gauge on the river map: on Blackburn Brook itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Sheffield Wincobank: 161 spills over 415 hours in total, across all 14.
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 Blackburn Brook includes the smaller streams that join it there.
Within 3 km of one of Blackburn Brook’s gauges in a straight line, but the river map cannot say whether their water reaches it.
8 more near these gauges whose connection is not known.
14 other overflows within 3 km of these gauges are placed below Blackburn 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.
7 sampling points on the Blackburn Brook and the streams that join it above Sheffield Wincobank, and below it. 1 has a sample from the last 12 months; 1 has 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.
