Purau Stream
A stream of the city, 6.9 km as the open map draws it, crossing 2 suburbs. Also recorded as “Purau”.
Where it runs
The centre of the water as OpenStreetMap draws it, centrelines, not banks, and not every reach carries water year-round. The faint outlines are suburbs.
Can you swim here
Purau Bay, the LAWA monitor that is ~250 m away, its latest weekly sample graded it suitable for swimming.
A water-quality risk grade, not a live verdict, after heavy rain any spot can turn. LAWA (Land Air Water Aotearoa) files the Canterbury sites for Environment Canterbury; its page is the one to check on the day.
The suburbs on its banks
The reports along it

The map also records “Purau”, the page answers to all of them.
It’s the centreline, the middle of the water as mapped on OpenStreetMap, not its banks. A line says where it runs, not how wide it is or whether it carries water today.
The record behind this
The line is OpenStreetMap’s, every named way tagged river, stream, drain or canal inside the city boundary, merged by name (ODbL). A line says where a waterway runs, not how wide it is; the live gauges are instruments, kept on /rivers.
