No clue about its identification. The pubescence on the stems and shape of the leaves made me think Solanaceae, but the flower petals are highly divided and not bell-shaped, and the stamen are small.

The dogs prevented additional photographs… they had to make sure I was paying attention to them.

I’m not sure what species of water lily this is, nor whether the small white flowers belong to it. My search led me to believe that the flower isn’t produced by the water lily, as it doesn’t appear that any Nymphaea or Nuphar produce similar flowers. Nuphar advena appears to be a common species in Georgia, but it produces robust yellow flowers, and Nuphar, if I remember correctly, often have less rounded leaves that extend out of shallow water.

The only water lily I’m familiar with in the US is Nymphaea ordorata, which was common is Ohio wetlands, but without the flower, I can’t confidently make an identification.
