Answer:

An oxbow lake is a uniquely shaped lake resulting from the path of a meandering river. Oxbow lakes are U-shaped or curved bends in a river that are cut off from the main river flow, forming a lake. An oxbow also refers to the horseshoe-shaped bends in rivers that can eventually become oxbow lakes.

Answer:

An oxbow lake is a U-shaped lake that forms when a wide meander of a river is cut off, creating a free-standing body of water. In south Texas, oxbows left by the Rio Grande are called resacas. In Australia, oxbow lakes are called billabongs. The word "oxbow" can also refer to a U-shaped bend in a river or stream, whether or not it is cut off from the main stream.[1][2]

This picture of the Nowitna River in Alaska shows two oxbow lakes – a short one at the bottom of the picture and a longer, more curved one at the middle-right. Furthermore, it can be clearly seen how a third oxbow lake is in the making. The isthmus or bank in the centre of the most prominent meander is very narrow – much narrower than the width of the river. Eventually, the two sections of river on either side of the isthmus break through, and create a new, straighter course. A new river bank then starts to accumulate, sealing off the meander and leaving another oxbow lake.
