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 Conon 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.

3 gauged tributaries, 4 gauges

Bran

Joins the Conon above Arcan Spillway, its highest gauge, no more than 35.7 km by river above Arcan Spillway.

Dosmucheran0.55 m 10m agoNormal

Its water passes every gauge on the Conon, from Arcan Spillway down.

Meig

Joins the Conon above Arcan Spillway, its highest gauge, no more than 22.5 km by river above Arcan Spillway.

Glenmeanie0.61 m 10m agoNormal

Its water passes every gauge on the Conon, from Arcan Spillway down.

Alltan Dubh name from the river map

Joins the Conon between Arcan Spillway and Moy Bridge, no more than 14.6 km by river above Moy Bridge.

Garve0.31 m 10m agoNormal

Its water passes Moy Bridge and every gauge below it on the Conon. It does not pass Arcan Spillway or the gauges above it.

Gauged streams joining the Alltan Dubh

  • Allt a' Ghlas-charnaich: joins the Alltan Dubh above Garve (its lowest gauge is 20.6 km by river above it). Gauge, source first: Allt a' Ghlas-charnaich Normal.

Where the Conon goes

No gauge below Conon Bridge 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 Conon Bridge 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 Conon’s gauges in a straight line, but the river map cannot say whether their water reaches it.

  • Conon Bridge Garrie View Lane CSO Not discharging
    Scottish Water · into River Conon · 300 m from Conon Bridge in a straight line · discharges into a tidal reach, where the water moves both ways · 2025: 0 overflow events, 0 h
  • Maryburgh Wwps CSO Not discharging
    Scottish Water · into River Conon · 730 m from Conon Bridge in a straight line · discharges into a tidal reach, where the water moves both ways · no official annual figure

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.
