As a general rule, you would prefer to have the sun behind the viewer, so that the surfaces facing the viewer are lit up brightly.
Backlighting using a sun position low on the horizon does reflect off the water very nicely. This can be used to hide underwater shadows.
However, sometimes you want to show the shadow of floating objects under the water. If your setting is on a shallow tropical bay, the water is often crystal clear and boats, canoes, etc. cast a crisp shadow on the sand below the surface.
This is only in the shallowest part though. Once the beach begins to slope downward into the bay, the shadows are broken up by the depths and also by the rippled patterns waves leave in the sand.
There's a guide for using
Set Water Lighting triggers to make dazzling screenies on any body of water.
Man, this makes me want to make some more eye candy. brb
