The column that we use is headed 64 (as we are 64km upstream of the datum point). In this example, a fairly even flow of between 0.7 and 1.0 metres per second is predicted throughout the day shown.
The normal maximum speed is about 1.6 metres per second.
A negative number would mean the current is flowing upstream, due to a rising tide.
During the low water months, when the speed of water is not so important, use the Water Levels feature to understand the dangers of low water.
