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.

Gauged tributaries

Streams and rivers with a gauge whose water joins the Dearne Washlands above one of its gauges, from the source down. The river map knows where gauges are, not every stream, so a tributary without a gauge is not listed here.

1 gauged tributary, 13 gauges

River Dearne

Joins the Dearne Washlands above Mexborough Pasture Road Pumping Station, its highest gauge, no more than 2.4 km by river above Mexborough Pasture Road Pumping Station.

Its water passes every gauge on the Dearne Washlands, from Mexborough Pasture Road Pumping Station down.

Where the Dearne Washlands goes

Below Mexborough Dearne Mouth, its water next reaches Sprotbrough, a gauge on River Don, 6.0 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.

Storm overflows upstream

70 storm overflows are traced upstream of Mexborough Dearne Mouth, the Dearne Washlands’s lowest gauge on the river map: on the Dearne Washlands itself, on its gauged tributaries, and on smaller streams that join above there.

  • 0 report discharging now
  • 67 not discharging
  • 3 offline or silent: 3 monitor offline, 0 status unknown, 0 no live feed

Official figures for 2025, for the overflows traced upstream of Mexborough Dearne Mouth: 1,495 spills over 9,312 hours in total, across all 70.

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 Washlands includes the smaller streams that join it there. Every overflow traced is listed here, each stretch in full. Back to the short lists →

11 other overflows within 3 km of these gauges are placed below the Dearne Washlands’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.

Water samples

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 Dearne Washlands and the streams that join it above Mexborough Dearne Mouth. 19 have a sample from the last 12 months; 24 have any sample banked.

Sampled most recently, anywhere on the Dearne Washlands and its streams:

Where, from the source downSampling pointsNewest sample
River Dearne and its streamsjoins the Dearne Washlands above Mexborough Pasture Road Pumping Station58 points24 sampled11 Sep 2026

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.
