Explanation:

The Oxbow lakes mostly form during the period of a flood. the water of the river is looking for the swiftest and the most directed route so instead of flowing around the meander it cuts through straight across it and flows.Oxbow lakes start as a meander during a flood and form the new channel. the water in it becomes stagnant for a long time and forms a lake until the water in it gets dry out.
