Ever Notice how Pools are Death Traps?

Through swimming in an inground pool over the past week or two, I've noticed a huge amount of living things that get caught and die (drown) in it. This includes mice, toads, frogs, cicada, dragonfly, worms, crickets, grasshoppers, ants, spiders, and many other unidentifiable bugs. It would seem that the sudden drop into the water makes it nearly impossible for entrapped creatures to climb back out. Anyone else notice this?

This happens to a lesser extent in ponds lakes and streams as well, however the food web takes care of the "leftovers" so you don't notice it as much.....

We take the ecosystem out of that water so we are the cleanup crew....
