Your average depth works out to about 4.5 feet. The gallons in a pool is equal to Length x Width x Average Depth x 7.5. So your pool has 33x15x4.5x7.5, which is 16700 gallons (16706.25 by calculation).

For a rectangular pool and assuming the shallow end is the standard 3 feet deep, the total volume will be about 14,541 gallons of water.
If the pool is 8 feet in the deep end and 3 feet in the shallow end, the total volume will be about 38,507 gallons of water.
If the pool is 8 feet at the deep end and 3 feet at the shallow end, the total volume will be 39,494 gallons of water.
10000000 gallons of water ;) it's true, my teacher told me
If the pool is 8 feet in the deep end and 3 feet in the shallow end, the total volume will be about 59,900 gallons of water.
18,691.2 gallons if shallow end 4'
A pool that is 32 feet long, 16 feet wide and with a depth from 3 feet in the shallow end to 8 feet in the deep end has a capacity of about 21,070 gallons of water.
It really depends on the depth of the shallow end. However, let's say the shallow end is three feet deep. In that case, the pool holds up to about 22,980 gallons of water.
If the pool is a constant 9 feet deep the total volume would be 48,600 gallons. However, if 9 feet is only the deep end and the shallow end is 3 feet deep, the gallons changes to 32,400 gallons.
