In hydrology, stage is the water level in a river or stream with respect to a chosen reference height. [1] [2] It is commonly measured in units of feet.Stage is important because direct measurements of river discharge are very difficult while water surface elevation measurements are comparatively easy.
Example graph of stream stages showing Action Stage, Flood Stage, Moderate Stage, Major Stage, and Record Stage on a river. Flood stage is the water level, as read by a stream gauge or tide gauge, for a body of water at a particular location, measured from the level at which a body of water threatens lives, property, commerce, or travel.

A river is a natural freshwater stream that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons.
Rivers with an average discharge of 5,000 m 3 /s or greater, as a fraction of the estimated global total.. This article lists rivers by their average discharge measured in descending order of their water flow rate.
The international scale of river difficulty is an American system used to rate the difficulty of navigating a stretch of river, or a single (sometimes whitewater) rapid. [1] The scale was created by the American Whitewater Association to evaluate rivers throughout the world, hence international in the title. [ 2 ]
