Freezing Water
Water in Dwarf Fortress can freeze to become ice if the temperature is low enough and the water is exposed to the air. The tile must be tagged as 'Above Ground' in order for water to freeze.
Water at level 1/7 freezes to become an ice floor. Water at level 2/7 or greater freezes to become an ice wall. Any ice wall will return 7/7 water when melted, or can be mined for 1 boulder of ice.
Creatures on a water tile that freezes into an ice wall are instantly killed. Dwarves die with the message "<dwarf name> has been encased in ice". The ice wall must be melted or mined in order to regain the items.
Melting
Ice can melt when the temperature rises as part of the natural cycle of seasons. Some biomes may be frozen all year round and others may never freeze. Ice can also be melted by proximity to Template:L. An ice tile with magma above or beneath it, or within 2 tiles on the same z-level, will cause the ice to melt (or will prevent water freezing in the first place).
Climate
Freezing Template:Ls are the coldest, and water on them is typically in permafrost. Choosing to embark in one poses an interesting challenge and offers opportunities for substantial amounts of Template:L.
Settling
One of the first challenges presented by a freezing climate is the lack of Template:L in any conveniently drinkable form. Along with trees, water may be the hardest resource to obtain. The ice chunks left behind while digging through ice cannot be melted into drinking water. There are several ways to approach a freezing area. One of them is embarking with a Template:L in site, utilizing the natural obsidian surrounding it to create Template:L floodgates and mechanisms to effectively melt ice. Another is to penetrate to the cavern levels, which may have water in liquid form. Note that Template:L can be used to create buildings and workshops, which may be melted by Template:L or other heat sources, and constructions, which will never melt.
Cautions
While channeling ice and magma, supervise your miners to ensure they are not encased in cooling magma or freezing ice.
