My best guess on why the river rocks lining the bottom would be to discourage anyone from attempting to get into the water and wade across the pond to the island and discourage dog owners from use it as a play pool for their dogs.
My second and more reasonable guess is that a plain light coloured bottom will easily lead to unsightly and uneven algae growth. The use of the river rocks will balance out whatever algae growth may happen.
