Murky pools are small pools of water on the surface of the map. They can be filled with freshwater, saltwater or brackish water.
Murky pools act as a finite water source and a biome.
 As a water source
Drinking from a murky pool will give dwarves an unhappy thought. Dwarves will not normally drink from murky pools if they can at all help it; preferring alcohol, well water, or running water from a brook/stream/river over water from a murky pool.
Using water from a murky pool to wash injuries results in a higher chance of the wound becoming infected.
Sometimes the only water visible on the map is in murky pools. In hot and scorching climates, its typically a good idea to quickly create a cistern to collect the water from murky pools before it all evaporates.
 As a biome
There are six types of pools, divided in climate and the kind of water. They are listed in the following table:
|Temperate||Temperate brackish pool||Temperate freshwater pool||Temperate saltwater pool|
|Tropical||Tropical brackish pool||Tropical freshwater pool||Tropical saltwater pool|
These are also used for any dwarf-made pools of water, even those that may be connected to rivers.
In order to remove a murky pool, you must first remove the water. You can do this with a pump, or you can let pools evaporate in hot/scorching climates, or you can just dig into your pools from the side and let the water drain away and evaporate.
The bottom of a murky pool will keep its "murky pool" status, presumably to let the game know that water should collect there during rain storms. You can't build certain structures, including farm plots, on dry "murky pool" tiles.
To de-murk those tiles, simply build a paved road on top of them, and then remove it. The floor covered by the road will become standard soil once the road is removed. Be aware that once you do this the tiles won't gather rainwater anymore.
A drained Murky Pool tile will block trade depot access.
Only very few creatures are found in murky pools. There are:
- additionally Lungfish can be found in tropical pools
- Dragonflies and Acorn flies can be found near in pools in savage areas
- and Blood gnats can be observed in evil biomes
 Adventure Mode
Conducting combat around murky pools is dangerous, as you may dodge or be thrown into them and drown. Dried Murky Pools are even more dangerous, as no amount of Swimming skill can save you.
 Thawing and drowning
In fortress mode, frozen murky pools will, when they thaw, do so instantly. Any dwarf standing on the ice will plunge into the water with a risk of drowning if they can not find a nearby ramp quick enough. (unless they have Adequate or better swimming skill, the fall will stun them.). To reduce the chance of this happening, you can use traffic designations: mark the ice as restricted, and put a high traffic ring around the perimeter of the pool. Or, if you don't need to fish from it, you can construct a wall around it or a floor over it.
