It {{l|flow|flows}} from mountain springs, forming the world's {{l|ocean|oceans}}, {{l|lake|lakes}}, {{l|river|rivers}}, and {{l|brook|brooks}}. Water falls as {{l|rain}} and {{l|snow}}, and freezes into {{l|ice}}. Water is home to a variety of {{l|aquatic creatures}}. Many creatures can {{l|Swimmer|swim}} in deep water. Air-breathing creatures that are submerged in water can {{l|Swimmer#Drowning|drown}} in it. Water comes in two varieties: '''freshwater''', which makes up almost all inland water, and '''saltwater''', which fills the seas. In this version, some brooks and murky pools can be saltwater even if the fortress site is partially mountainous. It is not known if this is a bug. To tell the difference, attempt to set up a drinking zone including some of the water in question. If there are zero tiles of water source available, the water is saltwater. |
− | + | In the new system mud is now a {{l|contaminant}} which is created any time water covers an area. Any tiles that contain mud may be used for {{l|Agriculture|farming}}. | |
− | Water is displayed with the symbols {{Tile|≈| | + | Water is displayed with the symbols {{Tile|≈|#008|#999}} and {{Tile|~|#008|#999}}, sometimes colored different blues, and white, showing ripples. Water can also take on other colors indicating {{l|contaminant|contaminants}} such as '''mud''' and '''blood'''. (The game can be {{l|Technical_tricks#The_look_of_the_game|configured}} to show the depth instead). |
− | Dark-colored water symbols indicate the water is one | + | Dark-colored water symbols indicate the water is one {{l|Z-level}} below the camera level. Water has 7 depth levels per tile, with 1 being a shallow puddle, and 7 filling the tile completely. {{l|Dwarf|Dwarves}} can safely walk through water up to a depth of 4. Dwarves finding themselves in water at a depth of 5 or greater are at risk of drowning unless they are skilled at {{l|swimming}}. |

− | Water and | + | Water and {{l|magma}} are both {{l|flow|fluids}} which are constantly trying to '''{{l|flow}}''' into adjacent tiles until they have filled all available space or until they run out of fluid. Fluids move in 10 directions, up, down, and to the sides. Fluids cannot move diagonally up or down. Fluids at a depth of 1/7 no longer attempt to move unless they can move down. Fluids under {{l|pressure}} can be pushed up until the pressure equalizes. |

− | Contaminants that get into water currently can do very strange things. A pool of blood that gets covered by water will be pushed out of the water as the water flows creating more pools of blood at the edge of the water. Overflowing a large reservoir that contains contaminants of blood will generate a large amount of blood very quickly. This behavior is thought to be a bug. | + | Contaminants that get into water currently can do very strange things.
