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 Mole 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 Mole above Stafford Bridge, its highest gauge, no more than 2.2 km by river above Stafford Bridge.
| Ifield | 0.81 mASD 30m ago | Normal |
Its water passes every gauge on the Mole, from Stafford Bridge down.
Joins the Mole between Gatwick Airport and Horley, no more than 2.5 km by river above Horley.
| Maidenbower | 0.70 mASD 30m ago | Normal |
| 1.2 km by river | ||
| Three Bridges | 0.54 mASD 30m ago | Normal |
| 6.0 km by river | ||
| Gatwick Link | 0.09 mASD 30m ago | Normal |
Its water passes Horley and every gauge below it on the Mole. It does not pass Gatwick Airport or the gauges above it.
Joins the Mole between Horley and Kinnersley Manor, no more than 4.5 km by river above Kinnersley Manor.
| Peeks Brook Lane | 0.99 mASD 30m ago | Normal |
| 5.4 km by river | ||
| Bonehurst Bridge | 1.86 mASD 30m ago | Normal |
Its water passes Kinnersley Manor and every gauge below it on the Mole. It does not pass Horley or the gauges above it.
Joins the Mole between Kinnersley Manor and Dorking, no more than 19.3 km by river above Dorking.
| Salfords Bridge | 0.42 mASD 30m ago | Normal |
Its water passes Dorking and every gauge below it on the Mole. It does not pass Kinnersley Manor or the gauges above it.
Below Esher, its water next reaches Thames Ditton Island, a gauge on River Thames, 5.0 km by river downstream.
Joins the Mole between Mole Mills and Woodleigh, no more than 15.1 km by river above Woodleigh.
| Leehamford | 0.15 m 10h ago | Normal |
| 10.3 km by river | ||
| Newtown Bridge | 0.29 m 1h ago | Normal |
Its water passes Woodleigh and every gauge below it on the Mole. It does not pass Mole Mills or the gauges above it.
Below Woodleigh, its water next reaches Umberleigh, a gauge on River Taw, 17.6 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.
18 storm overflows are traced upstream of Esher, the Mole’s lowest gauge on the river map: on the Mole itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Esher: 506 spills over 6,435 hours in total, across the 17 that have a figure. 1 has no 2025 figure.
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 Mole includes the smaller streams that join it there.
Within 3 km of one of the Mole’s gauges in a straight line, but the river map cannot say whether their water reaches it.
9 storm overflows are traced upstream of Woodleigh, the Mole’s lowest gauge on the river map: on the Mole itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Woodleigh: 731 spills over 7,719 hours in total, across all 9.
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 Mole includes the smaller streams that join it there.
Within 3 km of one of the Mole’s gauges in a straight line, but the river map cannot say whether their water reaches it.
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.
Sampled most recently, anywhere on these rivers and their streams:
33 sampling points on the River Mole and the streams that join it above Esher. 17 have a sample from the last 12 months; 24 have any sample banked.

England's samples only. Each count opens the list of those points, nearest first, with the date of each one’s latest sample (the gauge’s “Upstream of here” list).
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.
