Hey, its the Clutha, not the Amazon.

Average flow is 508 cumecs and in 1999 it was 3500 cumecs at Clyde and 4200 cumecs at Roxburgh.

3500 cumecs...hmm √3500=59 so it is 30m x 5.9 m of water flowing at 20m sec =72 km hr!

This is about "normal" flow ... near the flood levels indicator I pictured ...

It was not the speed of water ... just the sheer VOLUME of water ... the lower end of the bridge pictured was touching the water ...

And I was duty flood controller. These photos were taken after the peak flow had already passed. The peak of the flood happened at 01:00 in the morning.
Photo 4 is where the tag is.
