I'm back at school now and it feels so much better swimming at my schools pool than at my local Y becasuse my school pool has a 13 feet deep end. the Y is shallow, its 3 feet on one end.
Deep water is so much better than shallow water.
Michael,there is water following you. You are right that there is turbulence.While this flow is not unidirectional it is primarily in the direction of motion. It is greatest at the surface(where one is as they approach the wall)so if you push off below 2 feet you will miss most of it.That is one reason you want to get at least to the flags before surfacing. You definitely want to push off at 90 degrees to the wall as any other direction will increase your drag. There was a study done when they were making one of the first "super pools" to see the optimum depth. They put colored crystals that slowly dissolved in the water at various depths and had swimmers swim over them. As I recall at 7 ft. there was no more motion of the colored water.
