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.

The normal range, identified with the light green band on the figure, is where observed levels or flows occur 50% of the time.

Hourly level and flow data values are the instantaneous measurement for the given time.
