PUT THE READINGS IN CONTEXT
Gauge height uses a station-specific reference and is not the river’s depth everywhere. Local rainfall, tributaries, tides and dam operations can affect readings differently. Open the individual gauge for its charts and available historical context.
These observations are not a flood warning or a recreation safety rating. Check official warnings, closures and local guidance before acting.
These retain their own pages and are not combined with this overview.
CURRENT OBSERVATIONS
Readings have their own timestamps. Compare each gauge with its own history—not the raw height at a different station. Missing data is not a zero or an all-clear.
Snapshot checked . Readings older than 6 hours are excluded at page load. This is an observation snapshot, not a forecast.
