What does this number measure?

Red River (Canada)–Assiniboine is listed in the North America group. The comparison follows a sequence of river branches, rather than straight-line distance. Selected route: Red (Canada) → Assiniboine → Souris. The length includes the named branches, not just the river bearing the first name. The documented value is rounded; the choice of source, lakes crossed, meanders and river mouth may change the published length.

This length follows the course adopted by the catalogue. Maps show simplified, sometimes partial courses; an independent bar represents the documented length, distinct from straight-line distance.

Compare the stated dimensions

The comparison uses the number in each fact sheet: altitude, height, diameter, length or distance, depending on the reference. Two values in metres do not necessarily describe the same property.

Source and limitations

Approximate documentary length, dependent on the branches and route selected; this reference establishes neither a definite record nor kilometre-level precision.

Top view of a simplified geographic outline of the Red (Canada)–Assiniboine, based on the available mapped segments. The locator drawing may be partial, and river systems may combine several branches. The channel width and the textures of the water and banks are interpreted; this is not a satellite photograph. Only the lower bar represents the reference length documented by the source; the width of the map above does not measure that length. Outline: Natural Earth, public domain. Licence: Public domain.
