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 Par River 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 Par River above Ponts Vale on the river map. Streams without a gauge are not counted here.

Where the Par River goes

No gauge below Ponts Vale 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

1 storm overflow is traced upstream of Ponts Vale, the Par River’s lowest gauge on the river map: on the Par River itself, on its gauged tributaries, and on smaller streams that join above there.

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

Official figures for 2025, for the overflow traced upstream of Ponts Vale: 86 spills over 1,558 hours.

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 Par River includes the smaller streams that join it there.

Near these gauges, connection not known

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

  • Rescorla CSO Not discharging
    South West Water · into Trib Of Par Sands (S) · 1.1 km from Luxulyan in a straight line · discharges to the sea, an estuary or tidal water · 2025: 7 spills, 2.4 h
  • Molinnis Combined Sewer Overflow Not discharging
    South West Water · into Tributary Of River Par · 2.1 km from Luxulyan in a straight line · several watercourses close by, nothing to choose between them · 2025: 48 spills, 112 h
  • Tredenham Close CSO Not discharging bathing water shellfish water
    South West Water · into St Blazey Stream · 2.1 km from Ponts Vale in a straight line · no mapped watercourse close enough to be sure · 2025: 7 spills, 17 h

1 other overflow within 3 km of these gauges is placed below the Par River’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.

20 sampling points on the Par River and the streams that join it above Ponts Vale, and below it. 4 have a sample from the last 12 months; 9 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.
