Streams and rivers with a gauge whose water joins the Aire Washlands 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.
6 gauged tributaries, 101 gauges
Each tributary’s water passes the gauge it joins above and every gauge below it on the Aire Washlands, and none of the gauges above where it joins. For each, the gauge nearest the Aire Washlands is shown; its own page lists the rest.

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.
