What is this late blooming yellow flower?

Found in SW lower Michigan, September 16. The plants were growing in the bed of a dried up corner of a lake/large pond. I thought this might be Bidens laevis but it isn't suppose to be found in Michigan. It doesn't seem to have leaves like B. cernua, which is recorded in MI. I also looked at B. connata and B. comosa but they don't seem correct either.
