How to read the upstream-to-downstream order
The order and distances come from where each gauge sits along the river line on the map. The gauge at the top of the list is the one closest to the source, and water passing it flows down past the next gauges in order.
The km column is an estimate along the line on the map. It shows the order of the gauges and is not the official length of the river. For some rivers the line starts below the true source. Gauges that sit far from the line are listed separately after the table.
The colour of each point shows the latest water level status against the bank. Use it as supporting information only.
