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 the Dearne 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 the Dearne between Denby Dale Norman Road and Darton, no more than 11.3 km by river above Darton.
| Skelmanthorpe Park Gate | 0.02 m 22m ago | Normal |
Its water passes Darton and every gauge below it on the Dearne. It does not pass Denby Dale Norman Road or the gauges above it.
Joins the Dearne between Darfield Bridge and Bolton Bridge, no more than 3.6 km by river above Bolton Bridge.
| Manvers Old Moor Lane | 0.35 m 22m ago | Low |
Its water passes Bolton Bridge and every gauge below it on the Dearne. It does not pass Darfield Bridge or the gauges above it.
Joins the Dearne between Darfield Bridge and Bolton Bridge, no more than 6.4 km by river above Bolton Bridge.
| Worsbrough | 0.07 m 22m ago | Low |
| 6.8 km by river | ||
| Stonyford Bridge | 0.13 m 22m ago | — |
Its water passes Bolton Bridge and every gauge below it on the Dearne. It does not pass Darfield Bridge or the gauges above it.
Joins the Dearne between Bolton Bridge and Adwick, no more than 5.0 km by river above Adwick.
| Wath upon Dearne | 0.09 m 22m ago | Low |
Its water passes Adwick and every gauge below it on the Dearne. It does not pass Bolton Bridge or the gauges above it.
Below Adwick, its water next reaches Mexborough Pasture Road Pumping Station, a gauge on Dearne Washlands, 2.4 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.
67 storm overflows are traced upstream of Adwick, the Dearne’s lowest gauge on the river map: on the Dearne itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Adwick: 1,461 spills over 9,177 hours in total, across all 67.
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 the Dearne includes the smaller streams that join it there. Where a stretch or a tributary has more than 4, the 3 discharging now or nearest its gauge are listed, the rest are counted, and every one is in that gauge’s “Upstream of here” list.

Within 3 km of one of the Dearne’s gauges in a straight line, but the river map cannot say whether their water reaches it.
25 more near these gauges whose connection is not known.
8 other overflows within 3 km of these gauges are placed below the Dearne’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.
58 sampling points on the River Dearne and the streams that join it above Adwick. 19 have a sample from the last 12 months; 24 have any sample banked.
Sampled most recently, anywhere on the Dearne and its streams:

England's samples only. Each count opens the list of those points, nearest first, with the date of each one’s latest sample (the gauge’s “Upstream of here” list).
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.
