High water: what to watch for

Fast water is stronger than it looks. Even shallow water across a road can move a car, and riverbanks can be undercut and give way without warning.

Upstream gauges on the same river usually show a rise first, which is a useful early warning.

Weather at the gauge

Rain in the last 3 days: 18 mm. Rain that falls upstream can take hours or days to show up at a river gauge.
