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.
Contains OS data © Crown copyright and database rights 2026.
Streams and rivers with a gauge whose water joins the Greta 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 Greta above Riddings Wood, its highest gauge, no more than 1.5 km by river above Riddings Wood.
| Threlkeld | 0.59 m 1h ago | Normal |
Its water passes every gauge on the Greta, from Riddings Wood down.
Joins the Greta above Riddings Wood, its highest gauge, no more than 7.1 km by river above Riddings Wood.
| Thirlmere | 0.15 m 1h ago | Normal |
Its water passes every gauge on the Greta, from Riddings Wood down.
Below Keswick Campsite, its water next reaches Portinscale, a gauge on River Derwent, 970 m by river downstream.
No gauged tributary joins the Greta above Rutherford Bridge on the river map. Streams without a gauge are not counted here.
Below Rutherford Bridge, its water next reaches Broken Scar, a gauge on River Tees, 33.4 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.

5 storm overflows are traced upstream of Keswick Campsite, the Greta’s lowest gauge on the river map: on the Greta itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Keswick Campsite: 175 spills over 466 hours in total, across all 5.
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 Greta includes the smaller streams that join it there.
Within 3 km of one of the Greta’s gauges in a straight line, but the river map cannot say whether their water reaches it.
4 other overflows within 3 km of these gauges are placed below the Greta’s lowest gauge or on another river, so not listed.
1 storm overflow is traced upstream of Rutherford Bridge, the Greta’s lowest gauge on the river map: on the Greta itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflow traced upstream of Rutherford Bridge: 34 spills over 164 hours.
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 Greta includes the smaller streams that join it there.
Within 3 km of one of the Greta’s gauges in a straight line, but the river map cannot say whether their water reaches it.
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.
Sampled most recently, anywhere on these rivers and their streams:
38 sampling points on the River Greta and the streams that join it above Keswick Campsite, and below it. 6 have a sample from the last 12 months; 13 have any sample banked.

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.
