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 Huish Level Rhyne 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.

5 gauged tributaries, 14 gauges

River Isle

Joins Huish Level Rhyne above Westover Pumping Station, its highest gauge, no more than 4.5 km by river above Westover Pumping Station.

West Moor Drain

Midelney0.98 mASD 34m agoNormal

Its water passes every gauge on Huish Level Rhyne, from Westover Pumping Station down.

Where Huish Level Rhyne goes

Below Westover Pumping Station, its water next reaches LANGPORT GREAT BOW, a gauge on River Parrett, 320 m 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.

Storm overflows upstream

55 storm overflows are traced upstream of Westover Pumping Station, Huish Level Rhyne’s lowest gauge on the river map: on Huish Level Rhyne itself, on its gauged tributaries, and on smaller streams that join above there.

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

Official figures for 2025, for the overflows traced upstream of Westover Pumping Station: 1,583 spills over 17,207 hours in total, across all 55.

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 Huish Level Rhyne includes the smaller streams that join it there. Every overflow traced is listed here, each stretch in full. Back to the short lists →

Near these gauges, connection not known

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

  • Curry Rivel Combined Sewer Overflow Not discharging
    Wessex Water · into Tributary Of Drayton Drain · 2.7 km from Westover Pumping Station in a straight line · its watercourse is not on the river map · 2025: 11 spills, 93 h

4 other overflows within 3 km of these gauges are placed below Huish Level Rhyne’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.

98 sampling points on the Huish Level Rhyne and the streams that join it above Westover Pumping Station, and below it. 51 have a sample from the last 12 months; 52 have any sample banked.

Sampled most recently, anywhere on Huish Level Rhyne and its streams:

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.
