Because there isn't much else to hear if the water is calm? Because sound bounces off water a bit, so the intensity doesn't drop off quite as fast?

Probably because there are no trees or other stuff to absorb the sound.
It also depends on the time of day, since the temperature inversion that occurs at twilight that causes sound to travel along the discontinuity in the atmosphere.

Suppose you are camping on the shore of a lake which is not too wide, maybe 1/2 a mile across or so. During the day you can see campers on the other side of the lake, but you cannot hear them. At night, however, you can not only see the campers on the other side of the lake but you can also hear their conversations as they sit around their camp fire. This phenomena is due to the refraction of sound waves....

There might also be refraction of sound waves at the boundary between the water and the air that causes sound to travel along the surface of the water.

Water does not absorb sound like trees and grass. Have you ever been under water in a pool and heard someone jump in?? Loud, ain't it?
