The term for a stagnant lake that forms along a winding river due to soil erosion, resulting in an abandoned stream cut off from the river, is called an "oxbow lake." These lakes are created when a meandering river erodes the land and eventually alters its course, leaving behind a crescent-shaped body of water. Over time, oxbow lakes can become stagnant and may support unique ecosystems.
