Live levels from 2 monitoring stations across Warwickshire, 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 Leam 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 Leam between Kites Hardwick and Eathorpe, no more than 15.4 km by river above Eathorpe.
| Southamstructure | 0.10 mASD 38m ago | Normal |
Its water passes Eathorpe and every gauge below it on the Leam. It does not pass Kites Hardwick or the gauges above it.
Below Eathorpe, its water next reaches Warwick, a gauge on River Avon, 18.5 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.
8 storm overflows are traced upstream of Eathorpe, the Leam’s lowest gauge on the river map: on the Leam itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Eathorpe: 150 spills over 1,324 hours in total, across all 8.
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 Leam includes the smaller streams that join it there.
Within 3 km of one of the Leam’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 Leam’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.
29 sampling points on the River Leam and the streams that join it above Eathorpe, and below it. 11 have a sample from the last 12 months; 17 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.
