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.
Streams and rivers with a gauge whose water joins the Dee (Grampian) 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.
18 storm overflows are traced upstream of Garthdee, the Dee (Grampian)’s lowest gauge on the river map: on the Dee (Grampian) itself, on its gauged tributaries, and on smaller streams that join above there.

Official figures for 2025, for the overflows traced upstream of Garthdee: 588 overflow events over 1,329 hours in total, across the 12 that have a figure. 2 had no data that year; 4 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 the Dee (Grampian) includes the smaller streams that join it there.
