## What it shows

- **1455**: source water-line features
- **2442**: drawn line parts
- **1:10M**: source cartographic scale

Use this map for regional geographic context. It does not establish complete stream coverage, upstream connectivity or current flow.

## Method

All source geometry, projected to Equal Earth. Line widths are visual styling, not discharge or navigability. Source segments can share names or have missing identifiers.

## Sources and reuse

Natural Earth rivers and lake centerlines; boundaries. Public domain.
