Water is sprayed onto the pool surface, creating a ripple effect, so the diver can see the surface. Without it, the water takes on a glass-like appearance, and all you can see is the bottom of the pool. The diver needs to be able to spot the water surface in order to enter the water correctly in the vertical position.
A pool this size can hold up to 17,770 gallons of water. This would completely fill the pool to the very top.

It is the Water Cube
Minimum Volume of water in an olympic swimming pool = 2,500,000 liters Source = Wikipedia (no reference as to temperature). Depends on size of pool. Average daily consumption of water by a 150 lb human exercising 20 minutes a day = 2.36 liters a day. Source = CSGN Network calculator. (My grandmother drinks less, the fat woman down the street drinks more.) 2,500,000 liters / 2.36 liters = 1060 liters a day. This does not include evaporation nor kids peeing in the pool. Steve I disagree entierly with your mathematics, it depends upon which planet the pool is located creating a variable surrounding the gravitational potential energy of the water.

You usually see them in diving competitions. The water spouting into the pool gives the divers perspective on the distance to the surface of the pool.
To wash off the chemicals of the pool water, especially the chlorine which is very drying
Divers don't make a big splash when diving into a pool because of the way they have their bodies straightened out. It's the difference between throwing a rock into water, vs. throwing a small stick into the water.
The small pool is a hot tub; divers go in to keep their muscles loose.
Most of the water will be scattered by the spinning winds as a spray.
because the water is so cold from a high dive they go in the wading pool to warm back up
Use extra chlorine for about a week to shock the pool. As long as the water stays clear, you don't have a problem. If the pool gets cloudy, consult a professional.
Divers go in the spa so they don't get cold after each dive.
Pool water is treated with chemicals to make it safe to swim in (young children frequently relieve themselves in the pool). The chemical are not good for the skin and therfore pool users should shower BEFORE (to go in clean) and AFTER (to wash of the chemicals) they use the pool.
Cover your pool if it will not be in use. Remove food sources for the bugs, other dead bugs and foliage. Spray existing bugs with soapy water.
Divers dive in the sea/water, not earth.
