A yazoo is a river or stream that flows parallel to a larger river for a considerable distance before eventually joining it. Imagine it like a sidekick river tagging along before finally merging with the main hero. Yazoo rivers often form because of natural levees, which are raised embankments along a main river that prevent the tributary from directly joining it. These rivers are found in areas with broad floodplains. The name specifically comes from the Yazoo River in Mississippi.
