Coverage shows valid readings received; the reporting interval is unknown, so a percentage is unavailable. Gaps may understate rainfall and are not treated as dry weather.
Water fills show relative rainfall, not flood risk. Hourly cards use rainfall intensity; 24 hours uses recorded wet-day percentiles; longer totals use estimated seasonal pace for the elapsed period. Grey means there is insufficient coverage or history for a comparison.

Explore recorded river changes and compare events after drier or wetter weeks.
