Live levels from 1 monitoring station across South Lanarkshire, updated every 15 minutes.
| Station | Level now | Status |
|---|---|---|
| Kirkmuirhill | 0.28 m 38m 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 the Nethan 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.
No gauged tributary joins the Nethan above Kirkmuirhill on the river map. Streams without a gauge are not counted here.
Below Kirkmuirhill, its water next reaches Blairston, a gauge on Clyde, 30.2 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.

4 storm overflows are traced upstream of Kirkmuirhill, the Nethan’s lowest gauge on the river map: on the Nethan itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Kirkmuirhill: 67 overflow events over 279 hours in total, across the 3 that have a figure. 1 had no data that year. Scottish Water counts overflow events, not the 12/24-hour spills counted in England and Wales, so this total cannot be set beside theirs.
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 Nethan includes the smaller streams that join it there.
Within 3 km of one of the Nethan’s gauges in a straight line, but the river map cannot say whether their water reaches it.
2 other overflows within 3 km of these gauges are placed below the Nethan’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.
