In Dwarf Fortress, the transition to cold or frosty biomes can create difficulties for you in the winter months. When the surface water freezes, your dwarves will be left without fresh water, and while the average dwarves can survive only on alcohol, wounded and dwarves need water to survive. Here's how to stop the freezing of water in Dwarf Fortress.
prevent the freezing of water, forcing it to be considered inside
Water will freeze only in cold biomes if it is designated as outside. As a result, you can prevent freezing of water sources if they are closed by the roof or redirected underground. With rivers and muddy pools, this can be as simple as building a roof with a floor or walls above them. Keep in mind that for muddy pools this will prevent their re-filling with rainwater, so this is only a temporary solution. In addition, you can create your own water sources by designating a hole or a pond and telling the dwarves to fill it with water.
To do this, use the zone function to designate a hole or a pond. You will need at least one square on the floor next to the open space. Then you can designate this area as a pond. This means that dwarves will use buckets to throw water there. Use this to create an artificial well inside your fort, which can be used as a source of water.
other sources of water?
Please note that there are simpler ways to find non-freezing water in your fortress than to build roofs, redirect rivers or make wells. Digging can detect unusual caves that sometimes contain water, ponds and other elements. These areas will not freeze without much intervention, so you can rely on them as a safe source of water. As an alternative, if you feel really ambitious, the aquifer can be used as an almost unlimited source of water.
