The Red River Floodway at the Floodway inlet, in operation during the 1997 flood. Gates in the Floodway control structure elevate the river stage upstream causing a portion of the river discharge to be diverted down the Floodway channel. The Floodway control structure is in the approximate centre of the photograph and the flow in the Floodway channel is towards the top of the photograph. The Floodway diverts a portion of the river discharge around Winnipeg preventing the stage of the river from overtopping dikes downstream. The Floodway channel in operation in 1999 during a moderate flood.
Flow is towards the base of the channel.
The turbulent white water near the mouth of the Floodway channel is generated from the tailrace associated with the Floodway drop structure. Particularly notable about this picture is that below the confluence, the Red River is again carrying its full discharge, but the entire river flow is contained within a stream-cut valley and does not spill across the plain of the Red River Valley. The confinement of the river reflects a slight, but obviously important, deepening and steepening of the stream-cut valley occupied by the river. Photograph 9 was taken on the same day as pictures 3 to 6 which depict the broad flood zone south of Winnipeg.
