## Questions, answered briefly

**How long is Walnut Stream?**

1.8 km as mapped, 11 ways in the open map, crossing 1 suburb.

**Which suburbs does Walnut Stream pass through?**

Akaroa.

**Is the line on the map the whole waterway?**

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 line is OpenStreetMap’s, named ways tagged river, stream, drain or canal inside the city boundary, merged by name (ODbL). Centrelines, not banks; the live gauges are instruments, kept at https://www.chch.live/rivers.
