Live levels from 1 monitoring station across Herefordshire, updated every 15 minutes.
| Station | Level now | Status |
|---|---|---|
| Leominster Osbourne Place | 0.48 mASD 1h 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.

Streams and rivers with a gauge whose water joins the Kenwater 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 Kenwater above Leominster Osbourne Place, its highest gauge.

Its water passes every gauge on the Kenwater, from Leominster Osbourne Place down.
Below Leominster Osbourne Place, its water next reaches Leominster Upper Marsh, a gauge on River Lugg (distance by river not measured).
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.

2 storm overflows are traced upstream of Leominster Osbourne Place, the Kenwater’s lowest gauge on the river map: on the Kenwater itself, on its gauged tributaries, and on smaller streams that join above there.
Official annual figures for the overflows traced upstream of Leominster Osbourne Place, each return added up on its own. The Environment Agency’s return, 2025: 122 spills over 700 hours, from the 1 that has a figure. Welsh Water’s own return, 2022: 31 spills over 163 hours, from the 1 that has a figure. These are two separate returns, so the figures are given side by side, not added together.
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 Kenwater includes the smaller streams that join it there.
Within 3 km of one of the Kenwater’s gauges in a straight line, but the river map cannot say whether their water reaches it.
1 other overflow within 3 km of these gauges is placed below the Kenwater’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.
2 sampling points on the Kenwater and the streams that join it above Leominster Osbourne Place. 1 has a sample from the last 12 months; 2 have any sample banked. Listed from the source down, grouped by the next gauge each one's water reaches.
| Sampling point | Watercourse (map) | Above the gauge | Last sample | Latest results (river water) |
|---|---|---|---|---|
| River Lugg at Rossers Bridge, Presteigne | River Lugg | 4.1 km | 5 Mar 2025 · 19 months ago | Oxygen 98.9%Temp 7.4 °CpH 8.13Ammonia below 0.03 mg/l |
| Lugg downstream of Hindwell Brook | River Lugg | 2.9 km | 23 Mar 2026 · 7 months ago | Oxygen 99.9%Temp 9.1 °CpH 8Ammonia below 0.03 mg/l |
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.
