Some new bodies of water I found were some inlets. I thought that was a cool one because I have never seen or learned about an inlet.
There were some. I think the reason for this is because the Arlington heights map was more zoomed in than the Illinois map.
There were a bunch,and the reason is because the
Illinois map is zoomed in and the united states map is more zoomed out.
Some names of bodies of water are lakes,rivers,inlets,etc. Some bodies of water I identified were all that are listed above in the last answer.
