Approximate - nearest available gauge. Use as general reference only.
This photo is an aerial shot from downstream, showing the river-right (photo left) fish passage, and the river-left (photo right) boating-bypass/play-park.
(NOTE: the fifth feature of the play park is blocked from view by the bridge.)
In this photo you can see that there are something near twice the number of 'steps' (rock-arch rapids) in the fish-ladder as in the play channel. While it may be possible to paddle down the river-right (fish-ladder) side of things, that side was not constructed to 'optimize' whitewater play as was the river-left side.
Flow on the gauge represents approximated full flow of the river. Since the river is flow is split between the fish ladder and the whitewater channel, flow in the whitewater channel is not readily determined.
