What the colours mean
MinorModerate +Quiet or unclassifiedA river in flood is drawn in its class colour — amber at minor, red at moderate and above — and that always takes the line. Everything else is drawn in one of three hues that only separate neighbouring systems from each other; they carry no meaning of their own. Colour is never depth. Hover any line for its name.The map opens on rivers that are rising or at/above minor. All shows every system. Lines join gauges on the same river; for 247 of 681 they follow gauge positions, not a surveyed course. Where consecutive gauges are more than ~120 km apart the line breaks (30 rivers) — we do not know what the river does in between.Coastline and relief from Natural Earth (public domain); relief is real terrain derived from SRTM elevation, shown for context only.
Reading the map
Every dot is a river gauge and its colour is the Bureau of Meteorology’s flood class for that gauge, never a depth and never a temperature scale. A grey dot is a gauge that has not reported for more than ninety minutes: the river is doing something, but this is not the page that knows what.
The lines between dots join gauges on the same river. Where the course has been surveyed the line follows it; where it has not, the line follows the gauges themselves, which usually runs downstream and is not a claim about the channel. Open any gauge for its level against its own flood classes, its history and what is rising upstream of it.
