Meanders are produced when water in the stream channel erodes the sediments of an outer bend of a streambank and deposits this and other sediment on subsequent inner bends downstream. Once pools and riffles have developed, the river flows from side-to-side in a winding course. Formation of meanders explained | Britannica This is why you often see sand bars and beaches on the inside of the curve. Eventually, as silt and sediment clog the rivers main channel, the river will rise, ultimately switching channels, finding a path that is steeper and more direct in its path to the Gulf of Mexico, beginning the cycle all over again.

These meanders that became cut off from the rest of the river system create lakes known as abandoned meanders or oxbow lakes. The deepest part of the channel is on the outside of each bend. Where the bends of two meanders meet, they bypass the curve of river, creating an oxbow lake which may then be infilled with overwash sediment. Over time this deepens the river bed and creates steeper sides which are then weathered. A lake forms as the river finds a different, shorter, course.
