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.

== 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.

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.

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]].

== Issues ==
{{issue list|River}}

== Trivia ==
*Rivers 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 -->
