Live levels from 3 monitoring stations across Cambridgeshire, updated every 15 minutes.

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 Rhee 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.
Joins the Rhee between Wimpole and Haslingfield Burnt Mill, no more than 11.2 km by river above Haslingfield Burnt Mill.
| Whaddon | 0.43 mASD 49m ago | Normal |
Its water passes Haslingfield Burnt Mill and every gauge below it on the Rhee. It does not pass Wimpole or the gauges above it.
Joins the Rhee between Haslingfield Burnt Mill and Cambridge Byron's Pool, no more than 6.4 km by river above Cambridge Byron's Pool.
| Bourn Brook | 0.22 mASD 49m ago | Low |
| 8.5 km by river | ||
| Comberton | 0.10 mASD 49m ago | Normal |
Its water passes Cambridge Byron's Pool and every gauge below it on the Rhee. It does not pass Haslingfield Burnt Mill or the gauges above it.
Joins the Rhee between Haslingfield Burnt Mill and Cambridge Byron's Pool, no more than 9.2 km by river above Cambridge Byron's Pool.
| Great Chesterford | 0.12 mASD 49m ago | Normal |
| 12.9 km by river | ||
| Dernford | 0.07 mASD 49m ago | Low |

Its water passes Cambridge Byron's Pool and every gauge below it on the Rhee. It does not pass Haslingfield Burnt Mill or the gauges above it.
Below Cambridge Byron's Pool, its water next reaches Cambridge Jesus Lock, a gauge on River Cam, 5.8 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.
12 storm overflows are traced upstream of Cambridge Byron's Pool, the Rhee’s lowest gauge on the river map: on the Rhee itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Cambridge Byron's Pool: 129 spills over 265 hours in total, across all 12.
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 Rhee includes the smaller streams that join it there.
Within 3 km of one of the Rhee’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.
42 sampling points on the River Rhee and the streams that join it above Cambridge Byron's Pool, and below it. 28 have a sample from the last 12 months; 31 have any sample banked.
Sampled most recently, anywhere on the Rhee 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.
