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 135 of 246 they follow gauge positions, not a surveyed course. Where consecutive gauges are more than ~120 km apart the line breaks (18 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.
