What is a stream gauge?
A stream gauge is a device installed at a fixed point along a river or water body that measures the height of the water. Readings are sent automatically to monitoring centres. Each station has three threshold levels: Normal (the typical water height), Warning (water is rising and may cause flooding), and Danger (flooding is likely or already occurring). A station marked Active is currently transmitting live readings.
Live water level readings are only available where gauge stations are fully operational. Where telemetry is unavailable, reference threshold levels are shown instead.

Glossary
Key terms to help you understand stream gauge data and make better decisions
Current Level
The most recent water level reading from the gauge, measured in metres. Compare this to the Normal, Warning, and Danger levels to understand the risk.
Normal Level
The typical water height at this station during normal conditions. Readings near this level mean everything is fine.
Warning Level
The water height at which flooding becomes possible. Start preparing to move people, livestock, and valuables to higher ground.
Danger Level
The water height at which flooding is likely or already occurring. Take immediate action and follow evacuation routes.
Severity Level
A colour-coded status showing how concerning the reading is: Normal (green), Rising, Elevated, Warning (amber), or Critical (red).
Flow Ratio
How close the current water level is to the danger threshold, shown as the filled bar on each gauge card. A fuller bar means higher risk.
Telemetry Status
Whether the station is actively transmitting data. Active stations provide live readings; Degraded or Offline stations show reference thresholds only.
Last Reading
The date and time of the most recent water level measurement from this station. Older readings may mean the station is no longer reporting.
