Also on the Wey by the river map, but filed under another river name: BROADWEY.

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.

Gauged tributaries

Streams and rivers with a gauge whose water joins the Wey above one of its gauges, from the source down. Named streams without a gauge that have a page here are listed at the end.

River Wey — Wey

5 gauged tributaries, 9 gauges

Caker Stream

Joins the Wey between Passfield Mill and Farnham, no more than 18.0 km by river above Farnham.

Caker Streamstructure-0.12 mASD 35m agoLow

Its water passes Farnham and every gauge below it on the Wey. It does not pass Passfield Mill or the gauges above it.

Tilling Bourne name from the river map

Joins the Wey between Godalming and Guildford, no more than 2.7 km by river above Guildford.

Shalford0.12 mASD 35m agoNormal

Its water passes Guildford and every gauge below it on the Wey. It does not pass Godalming or the gauges above it.

Gauged streams joining Tilling Bourne

  • Lawbrook: joins Tilling Bourne above Shalford (its lowest gauge is 6.6 km by river above it). Gauge, source first: Albury Normal.

East Clandon Stream

Joins the Wey between Newark Weir and Brooklands, no more than 9.3 km by river above Brooklands.

The Bourne name from the river map

Joins the Wey between Brooklands and Weybridge, no more than 1.1 km by river above Weybridge.

Grants Bridge0.35 mASD 2h agoNormal
14.6 km by river
Addlestone0.31 mASD 50m agoLow

Its water passes Weybridge and every gauge below it on the Wey. It does not pass Brooklands or the gauges above it.

Gauged streams joining The Bourne

  • Mill Bourne: joins The Bourne above Addlestone (its lowest gauge is 12.8 km by river above it). Gauge, source first: Millbourne Bridge Normal; and 1 more gauge further up (see its own page).

Where the Wey goes

Below Weybridge, its water next reaches Shepperton Lock, a gauge on River Thames, 1.5 km by river downstream.

River Wey — West Dorset Streams

No gauged tributary joins the Wey above Broadwey on the river map. Streams without a gauge are not counted here.

Where the Wey goes

Below Broadwey, its water next reaches Weymouth, a gauge on an unnamed watercourse (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.

River Wey — Wey

Streams without a gauge

Named streams on the river map that flow into the Wey and have no gauge of their own. Each has a page with what is known about it: the next gauge downstream, and any storm overflows or water-sampling points placed on it.

Storm overflows upstream

River Wey — Wey

16 storm overflows are traced upstream of Weybridge, the Wey’s lowest gauge on the river map: on the Wey itself, on its gauged tributaries, and on smaller streams that join above there.

  • 0 report discharging now
  • 16 not discharging
  • 0 offline or silent: 0 monitor offline, 0 status unknown, 0 no live feed

Official figures for 2025, for the overflows traced upstream of Weybridge: 237 spills over 2,869 hours in total, across all 16.

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 Wey includes the smaller streams that join it there.

River Wey — West Dorset Streams

None of the storm overflows FloodRadar holds is traced upstream of Broadwey 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.

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.

Water samples

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.

River Wey — Wey

35 sampling points on the River Wey and the streams that join it above Weybridge, and below it. 22 have a sample from the last 12 months; 29 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.
