{{Infobox biome
A '''river''' is a common [[biome]]. Rivers can serve as borders between various other biomes, and usually lead to [[ocean]]s, although they can also form loops.
| title = River
 
== Description ==
Rivers are thin, lengthy biomes that frequently generate across the world. They typically serve as a division between two different biomes, but can also split a single biome in two. They are filled with [[water]] up to sea level, though rivers may run dry in certain areas due to higher than usual elevation. Saddle valleys in [[mountains]] can generate rivers, but often too high so that there's not any water. Rivers can vary a lot in width and depth, in generally flat areas rivers are usually around 10 blocks deep but in mountainous regions rivers can reach over 30 blocks in depth which is comparable to deep oceans. Sometimes rivers can also generate as lakes with small islands.
 
Exposed grass in rivers takes on a bluish-green hue and oak trees can rarely generate along with spare grass. Riverbeds consist of [[dirt]], [[sand]], [[gravel]], and [[clay]], and are one of the few places where clay generates, alongside lakes, [[swamp]] marshes, ocean hilltops, and [[lush caves]]. [[Sugar cane]] occasionally generates on the riverbank. [[Salmon]] and [[squid]] may spawn here.
 
== Variants ==
There are two different river biomes.

A '''river''' is a common [[biome]]. Rivers can serve as borders between various other biomes, and usually lead to [[ocean]]s, although they can also form loops.
The standard river variant. This is a very common biome in the game. The grass color is turquoise green, similar to the meadow and birch forest biomes. Vegetation is sparse, with occasional [[oak]] trees. [[Seagrass]] generates atop the riverbed.
 
== Description ==
Rivers are thin, lengthy biomes that frequently generate across the [[Overworld]], making up about 6.2% of the Overworld's area. They typically serve as a division between two different biomes, but can also split a single biome in two. They are filled with [[water]] up to sea level, though rivers may run dry in certain areas due to higher than usual elevation. Saddle valleys in [[mountains]] can generate rivers, but often too high so that there's not any water. Rivers can vary a lot in width and depth, in generally flat areas rivers are usually around 10 blocks deep but in mountainous regions rivers can reach over 30 blocks in depth which is comparable to deep oceans. Sometimes rivers can also generate as lakes with small islands. Rivers often make giant loops as well, due to a quirk in the terrain generator.
 
[[Salmon]] and [[squid]] may spawn here. Along the riverbanks, occasional [[Bush|bushes]] and [[Firefly Bush|firefly bushes]] can be found, and [[Sugar Cane|sugar cane]] grows adjacent to water. Exposed grass takes on a bluish-green hue, similar to the meadow and birch forest biomes, and oak trees can rarely generate where there is available space. Riverbeds consist of [[dirt]], [[sand]], [[gravel]], and [[clay]], and are one of the few places where clay generates, alongside lakes, [[swamp]] marshes, ocean hilltops, and [[lush caves]]. Atop the riverbed, [[seagrass]] commonly grows.
 
Neither passive nor hostile{{only|bedrock|short=1}} [[mob]]s (except [[drowned]]) spawn within river biomes themselves, but frequently wander into them from the surrounding biomes if they can spawn there. Drowned can spawn underwater, as can [[salmon]] and [[squid]].
 
== Mobs ==
The following mobs are naturally spawned here：

'''Frozen Rivers''' replace regular rivers in regions with snowy biomes. As the name implies, the top layer of water is entirely frozen. Seagrass does not generate on the riverbed. While sugar cane can generate alongside a frozen riverbank, it often quickly uproots itself after generation due to the water being frozen. Oak trees and grass can still generate here if this biome generates on land. Sometimes, frozen rivers can generate next to {{BiomeLink|Taiga|regular taiga biomes}}, resulting in incorrect and weird generation.

== Trivia ==
*Both types of riversRivers override [[ravine]]s at or close to the surface level, causing the ravine to be abruptly cut off by a wall of stone. However, if the ravine is long enough, it may continue on the other side of the river.
**Ravines can generate underground in river biomes without being cut off.<!-- tested with river biome scale set to 9999999 -->
