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 Forth 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.
Its water passes Craigforth and every gauge below it on the Forth. It does not pass Gargunnock or the gauges above it.
Gauged streams joining the Teith
Eas Gobhain: joins the Teith above Callander (its lowest gauge is 3.2 km by river above it). Gauge, source first: Loch VenacharNormal; and 1 more gauge further up (see its own page).
Leny: joins the Teith above Callander (its lowest gauge is 6.2 km by river above it). Gauge, source first: AnieNormal; and 3 more gauges further up (see its own page).
Where the Forth goes
No gauge below Craigforth is known on the river map.
8 storm overflows are traced upstream of Craigforth, the Forth’s lowest gauge on the river map: on the Forth itself, on its gauged tributaries, and on smaller streams that join above there.

Official figures for 2025, for the overflows traced upstream of Craigforth: 357 overflow events over 362 hours in total, across the 3 that have a figure. 5 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 Forth includes the smaller streams that join it there.
