A lake is a biome; it is a large area covered with water. Lakes can be filled with freshwater, saltwater or brackish water. Lakes have slopes leading into the water, making them ideal for learning how to swim in adventure mode.
The settings you choose during World generation have a large impact on how many lakes will be formed. For example, a Large Island world will typically have many fewer lakes than a Large Region world.
There are six types of lakes, divided by climate and the salinity of the water. They are listed in the following table:
|Temperate||Temperate brackish lake||Temperate freshwater lake||Temperate saltwater lake|
|Tropical||Tropical brackish lake||Tropical freshwater lake||Tropical saltwater lake|
