Oxbow Lake - English Definition & Meaning

Definition

An "oxbow lake" is a U-shaped lake formed when a wide meander from a river is cut off, creating a free-standing body of water. Rivers tend to erode the outer banks of a meander, gradually widening and curving its path. During floods, a river may cut directly across the neck of a meander, shortening the river's course. This leaves the old meander isolated from the main channel. Over time, sediment seals off the ends of the meander, forming a distinct, curved lake. 🏞️ Think of it as a river's abandoned loop.

Etymology

The name "oxbow lake" comes from the lake's distinctive shape, which resembles the bow of an ox yoke. "Oxbow" refers to the U-shaped piece of wood that fits around the neck of an ox when it is pulling a plow or cart. The term was first used in areas where ox-drawn plows were common. "Lake" simply refers to a body of water. The formation process has been understood since the study of fluvial geomorphology became prominent.
