the pool is right around 9-10 feet deep at the point where you land off the single. At the deepest, and far from where you can land, it gets up to 17 feet deep. The reason is because originally they intended to have diving boards at the far end but for some reason it never worked out.
on a side note, I tried leashes one year and they sucked because you have to deal with taking them on and off each time to get out of the pool... only to have to tie them back up at the top. Its really not too are to dive down and the a ski on occasion with your boots still on
