Current as of when?
A whirlpool. An eddy is water that flows opposite from the normal flow of a river. When a river's water level rises, tributaries that point in the opposite direstion of the flow of the river will rise too. This water will flow upstream in the tributaries and fill them to the level of the river. In some regional areas, such as southern states of the US, an eddy is a part of a river that is set off from the river where the water has no flow at all unless the river is rising.
River level falls when there is drought because there is less rainfall and so the water water in the rivers shrinks/reduces.Pakistan.
