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 Irthing above one of its gauges, from the source down. Named streams without a gauge that have a page here are listed at the end.

3 gauged tributaries, 3 gauges

Brampton Beck

Joins the Irthing above Greenholme, its highest gauge, no more than 7.9 km by river above Greenholme.

Brampton Moat Side0.04 m 27m agoLow

Its water passes every gauge on the Irthing, from Greenholme down.

Coal Burn

Joins the Irthing above Greenholme, its highest gauge, no more than 48.2 km by river above Greenholme.

Coalburn Beck0.14 m 27m agoNormal

Its water passes every gauge on the Irthing, from Greenholme down.

River Gelt

Joins the Irthing above Greenholme, its highest gauge, no more than 11.8 km by river above Greenholme.

Hynam Bridge0.39 m 4h agoNormal

Its water passes every gauge on the Irthing, from Greenholme down.

Where the Irthing goes

Below Greenholme, its water next reaches Linstock, a gauge on River Eden, 10.3 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.

Streams without a gauge

Named streams on the river map that flow into the Irthing and have no gauge of their own. Each has a page with what is known about it: the next gauge downstream, and any storm overflows or water-sampling points placed on it.

  • Cam Beck (joins about 6.7 km above Greenholme)
  • King Water (joins about 9.2 km above Greenholme)

Storm overflows upstream

9 storm overflows are traced upstream of Greenholme, the Irthing’s lowest gauge on the river map: on the Irthing itself, on its gauged tributaries, and on smaller streams that join above there.

  • 0 report discharging now
  • 7 not discharging
  • 2 offline or silent: 1 monitor offline, 1 status unknown, 0 no live feed

Official figures for 2025, for the overflows traced upstream of Greenholme: 294 spills over 855 hours in total, across all 9.

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 Irthing includes the smaller streams that join it there.

Near these gauges, connection not known

Within 3 km of one of the Irthing’s gauges in a straight line, but the river map cannot say whether their water reaches it.

  • Hayton Pumping Station Not discharging
    United Utilities · into Bye Gill · 1.9 km from Greenholme in a straight line · its watercourse is not on the river map · 2025: 6 spills, 0.5 h
  • Heads Nook Pumping Station Not discharging
    United Utilities · into Trib Trout Beck · 2.9 km from Greenholme in a straight line · no mapped watercourse close enough to be sure · 2025: 0 spills, 0 h

4 other overflows within 3 km of these gauges are placed below the Irthing’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.

24 sampling points on the River Irthing and the streams that join it above Greenholme, and below it. 10 have a sample from the last 12 months; 13 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.
