Oxbow lakes - How U-shaped lakes are formed

An oxbow lake is a free-standing waterbody that forms from wide curves (meanders) in a river channel. They are also called horseshoe lakes, loop lakes, and cut-off lakes. Over time, a river or creek may find a shorter course through the process of removing meanders. The meander corners closest to each other, called concave banks, slowly erode sediment and eventually pinch together. The banks opposite concave banks are called convex banks, and silt and sediment are deposited here.
