________ is a barrier created in a waterway or depression

Explanation:
A dam is a barrier built across a river or stream to hold back water and create a reservoir. It fits the description because it is placed directly in the waterway, blocking flow. Levees and dikes are raised embankments along the sides of a river or coast to prevent flooding, not barriers across the channel. A barricade is a general obstacle, not a water-control structure. So the barrier created in a waterway or depression is a dam.
