About this data
Average daily flow is measured in cubic metres per second (m3/s).
Water level is measured in metres according to the geodetic reference above mean sea level and is either the level measured at 24:00 (midnight) or the daily average.
The median is used to represent the long-term average value.
Hourly level and flow data values are the instantaneous measurement for the given time.
