Live levels from 2 monitoring stations across Hampshire, 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.
Contains OS data © Crown copyright and database rights 2026.
Streams and rivers with a gauge whose water joins the Swift 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 Swift above St Bedes on the river map. Streams without a gauge are not counted here.
Below St Bedes, its water next reaches ALLBROOK GS, a gauge on The Itchen Navigation, 10.0 km by river downstream.
No gauged tributary joins the Swift above Churchover on the river map. Streams without a gauge are not counted here.
Below Churchover, its water next reaches Rugby, a gauge on River Avon, 5.9 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.

None of the storm overflows FloodRadar holds is traced upstream of St Bedes on the river map. That is not the same as none: the map leaves out many small streams and culverts, so an overflow it cannot place may still drain here, and not every company publishes every overflow.
Within 3 km of one of the Swift’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 Swift’s lowest gauge or on another river, so not listed.
3 storm overflows are traced upstream of Churchover, the Swift’s lowest gauge on the river map: on the Swift itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Churchover: 83 spills over 583 hours in total, across all 3.
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 Swift includes the smaller streams that join it there.
1 other overflow within 3 km of these gauges is placed below the Swift’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 River Swift and the streams that join it above St Bedes. 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.

17 sampling points on the River Swift and the streams that join it above Churchover, and below it. 5 have a sample from the last 12 months; 5 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.
