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 Bonny Water above one of its gauges, from the source down. Named streams without a gauge that have a page here are listed at the end.

No gauged tributary joins Bonny Water above Bonnybridge on the river map. Streams without a gauge are not counted here.

Where Bonny Water goes

No gauge below Bonnybridge 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.

Streams without a gauge

Named streams on the river map that flow into Bonny Water and have no gauge of their own. Each has a page with what is known about it: the next gauge downstream, and any storm overflows or water-sampling points placed on it.

  • Red Burn (joins about 5.2 km above Bonnybridge)

Storm overflows upstream

3 storm overflows are traced upstream of Bonnybridge, Bonny Water’s lowest gauge on the river map: on Bonny Water itself, on its gauged tributaries, and on smaller streams that join above there.

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

Official figures for 2025, for the overflows traced upstream of Bonnybridge: 64 overflow events over 294 hours, from the 1 that has a figure. 2 have no 2025 figure. Scottish Water counts overflow events, not the 12/24-hour spills counted in England and Wales, so this total cannot be set beside theirs.

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 Bonny Water includes the smaller streams that join it there.

2 other overflows within 3 km of these gauges are placed below Bonny Water’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.
