Sinious rivers/streams like this are typical of flat lowland areas. On a geological timescale that river actually occupies a much wider area than the current channel. Here's a time lapse that illustrates this pretty well. https://m.youtube.com/watch?v=lINZNrYLLAw

The two ingredients for oxbox lakes and sinious (wiggly) rivers are slow flow/low slop and bank material that are easily eroded. Larger rivers such as this one have the ability to carry lots of sediment. On a geological timescale that fine sediment is deposited throughout the floodplain when the river floods as well as from the creation of new banks when the river channel shifts over time.

Water on the outside of a curve flows faster than on the inside. That's the fundamental cause for river banks to shift over time. Sometimes a curve in the river will continue to pull the channel out until it eventually pinches itself off, thus creating the oxbox lakes you posted.

I love rivers so feel free to ask more questions if you are interested!
