Just a guess at this point, but I'd say less than a gallon per minute. The water flows out of the one end, drops down into a small creek which feeds a larger creek about 200 yards away.
That's why I was thinking this would be a multi person job if I were to take it on myself.
I'm just not sure if I want to sink thousands of dollars into this for a contractor to do it. I mean the water doesn't have a "pond" smell to it, the only negative thing is you can't stand cause of the muck. You just have to float!
