The largest moon of Saturn, Titan is the only body of the Solar System, other than our own Earth which retains a liquid on its surface. It's not water but liquid methane. Completely covered by a thick, smoggy atmosphere, its surface cannot be seen with visible light. Only by cloud-penetrating means such as radar mapping can give clues about what exists there. Which what the Cassini probe did.
So, that being said, I am at liberty to speculate. The lakes are near Titan's north pole so the sun, if visible at all through the clouds remains near the horizon. Saturn itself would not be in view at all, clouds or not. How the liquid methane would appear or behave is guesswork. Foam? Wet the stones and soil at the edge? I decided on none of it. Because who really knows?
