River levels & historical flood information
Winnipeg references its primary water level to a gauge located on the Red River at James Avenue. The gauge is just downstream of The Forks, at the junction of the Assiniboine River. The gauge is also known as the James Avenue Datum.
In a "normal" summer, water levels are maintained at around James 6.5 ft.
In the spring, a moderate flood will exceed James 18 ft. The zero point for this gauge is normal winter ice level and is established as 727.57 ft. above mean sea level.
Current river level information is available at City of Winnipeg – River Levels.
