Other paleochannels are better researched, but this one in Africa made the most dramatic picture (oxbow lakes are generally the same size as the river that made them)

I'm assuming it's from the last Green Sahara period, about 6000 yrs ago.
Less dramatic is the Rio Grande. Oxbow lake at top, and meander scars at bottom. According to researchers, these would all be from the Holocene.

Australia. Supposedly, most of the paleochannels around this river date from before the Holocene.

Re: Ancient climate change on google earth
I would be cautious about that statement, as 1,000 yr & 10,000 yr floods can make a huge river channel that normally isn't present. Cut the deep channel with a bigger flood and you would get a lake just like your first example with a tiny river in a deeper basin passing nearby.
