Hatches of many aquatic insect species are very common in spring. You see it more in rivers, but it can occur in lakes and ponds with the right habitat and species present. I fish a lake in PA that has such a heavy hatch of stone flies that even the walleye will surface feed on them right at dark! I have seen several ponds where you could catch bass, even ones in the four pound range using a dry fly matching the hatch. However, smaller bass are much more common dinner table customers on such fare.
