how deep is my pool

[Sully]

17' x33' w/ 8' deep end.

Need to know average depth..........depending on the average depth anywhere from 16K to 25K gallons, using 4 to 6 feet average depth respectively.

i say at about 5' is the middle marker. Low end of it is about 3.5' deep then step away to about 5', then slopes to 8' deep end. But I am not sure. I say 22K gallons?
