20,500 gallons
15' x 24' oval pool with 54" wall has 8,823 gallons of water.
formula for determining how many gallons in a pool is, length times width times average depth times 7.5 = gallons of water in pool if it round or oval its times 5.9
If its an oval pool approx 7800 gallons at full capacity. If its rectangular pool then approx 9000 Gallons.

4500 US Gallons
Approximately 12,000 gallons.
What are your depths in the deep and shallow end and what shape is the pool? Rectangular, kidney, oval or irregular?
How large is the pool? In ground or above ground? Shape? Above ground is easier to calculate. I have an oval above ground pool which is 18 x 38. It holds approx. 15,000 gallons. To get an accurate answer, you need to be far more specific.
