Lake vs. River — What's the Difference?
By Tayyaba Rehman — Updated on October 3, 2023
A "Lake" is a large body of still water surrounded by land. A "River" is a flowing body of water that moves continuously towards an ocean, sea, or another river. Both are freshwater sources, but lakes are static while rivers flow.

Key Differences
A Lake is a substantial inland body of standing water that has accumulated in a hollow or basin on the Earth's surface. These water bodies can vary significantly in size, from small ponds to massive bodies like the Great Lakes. They are often fed by rivers, streams, or underground springs, and they can have outlets, such as rivers or other waterways. Lakes often serve as significant freshwater reservoirs.
On the other hand, a River is a natural flowing watercourse. It originates from a source, which can be a spring, glacier, or lake, and it moves along a defined path until it reaches its endpoint, often an ocean, sea, or another lake. As it flows, a River might collect water from rainfall, snowmelt, or other tributaries, increasing its volume. Rivers play essential roles in shaping landscapes, facilitating transportation, and providing habitats for various species.
While both Lakes and Rivers are inland bodies of freshwater, their primary distinction lies in their state of motion. Lakes are primarily still, while Rivers are continuously moving. The ecosystem, aquatic life, and the surrounding environment of a Lake can differ greatly from that of a River due to this difference in motion and the varied depths of lakes.
Another point to note is that Rivers often feed lakes. For instance, several rivers might flow into a lake, providing it with a continuous supply of fresh water. Conversely, lakes can also be sources of rivers. This interdependence highlights the intricate relationship between Lakes and Rivers in nature.

Lake
A lake is an area filled with water, localized in a basin, surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although like the much larger oceans, they form part of Earth's water cycle.
River
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water.
