How do oxbow lakes form? What will be an ideal response?
Low-gradient river systems are commonly dominated by meandering channel patterns characterized by
tight looping bends shaped like curves in a winding mountain road. These channels migrate through
time. In some instances, the curvature of the channels becomes so pronounced that two channels will
actually intersect each other and form what is called a cut off. The term cutoff is applied because one
bend of the river gets essentially amputated and isolated from the rest of the river. As water continues
to flow through the cutoff, the water left in the abandoned channel becomes a stagnant lake. This lake
is called an oxbow lake.
