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 Cheddar Yeo 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 Cheddar Yeo above Cheddar Gorge on the river map. Streams without a gauge are not counted here.

Where the Cheddar Yeo goes

No gauge below Cheddar Gorge is known on the river map.

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.

Storm overflows upstream

None of the storm overflows FloodRadar holds is traced upstream of Cheddar Gorge 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.

Near these gauges, connection not known

Within 3 km of one of the Cheddar Yeo’s gauges in a straight line, but the river map cannot say whether their water reaches it.

  • Froglands Pumping Station Not discharging
    Wessex Water · into River Yeo (S) · 1.1 km from Cheddar Gorge in a straight line · its recorded watercourse is not the one mapped beside it · 2025: 38 spills, 82 h
  • 41 Wideatts Road CSO Not discharging
    Wessex Water · into Helliers Stream Via Sws · 1.5 km from Cheddar Gorge in a straight line · its watercourse is not on the river map · 2025: 10 spills, 57 h

2 other overflows within 3 km of these gauges are placed below the Cheddar Yeo’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.

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.

4 sampling points on the Cheddar Yeo and the streams that join it above Cheddar Gorge, and below it. 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.

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.
