I’m now thinking it is a variety of white water buttercup or crowfoot. The only difference I’m seeing between the online descriptions and what I have is the lack of a different leaf at the surface. The flower is spot on and it is native to this area.

Any suggestions on getting rid of it? I will look into professional help, but I’m not aware of any in this region.
