The pond is full of algae and not much cover for wildlife right now, but hopefully that should change. In the past, mallards have nested in the ravine, into which the water from this pond flows, and they have also attempted nesting amongst the dead cattails (last year's cattails) on the shore. But as there is no vegetation whatsoever it is more difficult. Yet, I found a pair of eggs deposited on the shore right out in the open, no attempt even at making a nest, though there is nothing to make a nest from. Not even sure they were laid by this female. Typically, mallards make a good deep nest lined with feathers.
