Current river levels

Why does the City use the river level at James Avenue as a reference?

Winnipeg references river levels by James Avenue Datum, meaning we determine river levels using data from a gauge located on the Red River at James Avenue, just north of the Forks.

While James Avenue is the City's main gauge used to determine river levels, there are also other monitored locations along the Red and Assiniboine rivers across Winnipeg.
