I had to look twice at the per hour, per second and tonnes instead of m³/s. 
I’m used to thinking in m³/s from kayaking, hence I went with tonnes/second as close enough. I was disappointed not to have an estimate from the original article of the gravitational force changes.
Assuming metric tonnes, here, right?
In the spirit of another ongoing thread on measurement systems I felt a comparison to some well known rivers might do the trick. 
In order not to end up shame-cross-posted to that thread I resisted scaling it against the Rhein, Danube, Nile, Congo, Mississippi, Colorado, Hudson, Amazon… Youghiogheny… Hope you don’t feel left out.
