I'm sure the driver of the concrete truck will have seen
this before. Offer him some money to help you pour, and
you'll get his advice for free.
My guess is that Jim is right, but I'd think about pumping
the water out after you have put a foot or two of the
concrete in. You'll want to punch down the concrete to
get the air out long before the hole is full. Have you ever
pushed a 2x4 through 6' of concrete?
Just make sure you have a pump on hand that can clear
the hole in 5 min or so. Then you have options.
