A deep end or deep center in an above ground pool is simply an area dug out in the earth to add up to an additional 2 feet of water depth to an above ground pool.

The Red Cross considers nine feet to be a good depth for diving if you want to be especially cautious, but the diving area in many pools is eight feet deep. Never dive into a pool that's less than eight feet deep. If you're unsure how deep a pool is, it's best to avoid diving there. It can be hard to gauge a pool's depth just by looking. Find a pool where the depth of the water is clearly marked. In many cases there will also be a sign posted that specifies diving is permitted there.
