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

2 gauged tributaries, 3 gauges

Evan Water

Joins the Annan between Meikleholm Bridge and Woodfoot, no more than 3.9 km by river above Woodfoot.

Beattock0.39 m 35m agoNormal

Its water passes Woodfoot and every gauge below it on the Annan. It does not pass Meikleholm Bridge or the gauges above it.

Kinnel Water

Joins the Annan between Woodfoot and Brydekirk, no more than 28.5 km by river above Brydekirk.

Redhall0.57 m 35m agoNormal
Bridgemuir0.72 m 35m agoNormal

Its water passes Brydekirk and every gauge below it on the Annan. It does not pass Woodfoot or the gauges above it.

Where the Annan goes

No gauge below Brydekirk 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 the Annan 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.

Storm overflows upstream

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

Official figures for 2025, for the overflows traced upstream of Brydekirk: 77 overflow events over 458 hours in total, across the 2 that have a figure. 2 had no data that year. 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 the Annan includes the smaller streams that join it there.

Near these gauges, connection not known

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

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.
