[OSM-talk] difference between waterway=canal and waterway=drain

[Andy Robinson (blackadder-lists)]

Both are created by man. A canal is normally navigable and a drain is not. A
canal is for carrying goods and people, a drain is for transporting water
much like a river but the drain has been dug by man rather than nature.
Drains can be anything from quite narrow watercourses to very large
constructions depending on how much water they carry.

Hope this helps.

Cheers
Andy
