The headwaters of a river are the smaller streams that feed a river, and make up the river's source. [4] These streams may be small and flow rapidly down the sides of mountains. [5] All of the land uphill of a river that feeds it with water in this way is in that river's drainage basin or watershed. [4]

This stream operating together with its environment can be thought of as forming a river ecosystem. River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.
Additionally, only one third of rivers are free-flowing due to the extensive use of dams, levees, hydropower, and habitat degradation. [16] Excessive water use has also caused intermittent streams to become more dry, which is dangerous because they are extremely important for water purification and habitat. [17]
