About these river level locations

Leatherhead is the main local gauge for the town, Fetcham and nearby riverside paths. Dorking / Box Hill is the closest upstream indication for Box Hill and the Stepping Stones area. Downside Bridge / Cobham and Esher show downstream conditions.

Data source: Environment Agency flood and river level data from the real-time data service.

Water quality caution

Use caution around river water

This page cannot say whether the River Mole is clean or safe for people or dogs. Water quality can change quickly after rain because of runoff, drains and older pollution events.
No current alert
No active storm overflows currently reported in the River Mole records. This page keeps water quality as a caution because the live overflow feed is only a rough signal, not a local water-quality clearance.
What this water quality signal means

Storm overflow source: Water UK / Stream national storm overflow dataset. Checked: 07:54, 21 Jul 2026.

Useful signal: this feed can show whether the national overflow data currently has active or recent River Mole catchment records.

Important limitation: the current feed rows do not identify a precise Leatherhead, Fetcham, Dorking, Cobham or Esher outfall. A record saying "River Mole" means catchment-level coverage, not a point on the riverbank.

Limited: the feed identifies River Mole catchment activity, but does not publish specific local outfall/site names for these rows. River Mole records visible in the feed: 2. Recent 7 days: 0.

Technical feed records: shown for transparency only. These labels are not local site names unless the feed supplies one.

Feed labelStatusLast reported activity
Monitored discharge affecting the River Mole Clear No recent event shown
Monitored tributary affecting the River Mole Clear No recent event shown

Better local context: River Mole River Watch is more useful for water-quality observations because it is focused on the River Mole catchment.

Official EA classifications are useful long-term background, but they are not today's pollution level.

Mole - Dorking to Leatherhead: Official Catchment Data Explorer water-body classification for the Box Hill / Stepping Stones area. Useful background, but not current pollution monitoring. Open EA page

Safety note: Please do not treat this page as a swimming, paddling or dog-safety clearance. River water can be polluted even when no overflow is currently active, especially after rain, because runoff, drains and older discharge events can still affect water quality.
