Live levels from 1 monitoring station across Lancashire, updated every 15 minutes.
| Station | Level now | Status |
|---|---|---|
| Carry Bridge | 0.08 m 32m ago | Normal |
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 Colne Water 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 Colne Water above Carry Bridge, its highest gauge, no more than 1.9 km by river above Carry Bridge.
| Trawden Brook | 0.05 m 32m ago | Normal |
Its water passes every gauge on Colne Water, from Carry Bridge down.
Below Carry Bridge, its water next reaches Reedyford, a gauge on Pendle Water, 5.2 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.

1 storm overflow is traced upstream of Carry Bridge, Colne Water’s lowest gauge on the river map: on Colne Water itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflow traced upstream of Carry Bridge: 3 spills over 6.0 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 Colne Water includes the smaller streams that join it there.
Within 3 km of one of Colne Water’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 Colne Water’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 Colne Water and the streams that join it above Carry Bridge, and below it. 1 has a sample from the last 12 months; 3 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.
