+ | [[farm plot|Farming]] is only possible on [[mud]] and soil. Any terrain can be made muddy, and therefore suitable for farming, by dumping water on it. In Dwarf Fortress, 'Irrigation' is used as a fancy word for dumping water onto terrain that isn't useful for farming, in order to make it so. | ||
Any amount of water dropped, pumped, or otherwise transported onto a tile will leave behind at least 'a dusting of mud', and this is sufficient for farming. Farm plots cannot be built on terrain with [[water depth|a water level of more than 1/7]], and more mud has no apparent effect on farm output, so it's best to use a minimum of water to irrigate. | Any amount of water dropped, pumped, or otherwise transported onto a tile will leave behind at least 'a dusting of mud', and this is sufficient for farming.

[[Magma]] cannot be used to irrigate, as it does not leave behind mud. It's usually best not to confuse molten rock and liquid water, although the use of both in tandem may help with schemes to irrigate [[glacier|glaciers]]. | [[Magma]] cannot be used to irrigate, as it does not leave behind mud.

− | + | This method ranks somewhere between easy and complex irrigation as it's set up relatively quickly while not necessarily looking as cool as the complex method. It needs a [[screw pump]] and a river or brook next to a hillside. | |
+ | |||
+ | You start by digging out a tunnel of one tile and a rectangular room near the river exactly one level above the river. The floor of the room has to be at the same level as the surface of the river. It doesn't have to be walled on the side of the river as you'll need some open space for the water to get out. If you have dug it farther away from the river, you should dig another tunnel from the room to the water source so that the pumped in water can get out. | ||
+ | |||
+ | Secondly, at the end of the one tile wide tunnel you'll set up the pump. You'll need a free place next to the light green part of the pump for a dwarf to be able to operate it. It will only be operated once, so you don't need any axles or gears or waterwheels or whatever. Manual pump operation is all it takes. | ||
+ | |||
+ | After setting up the pump (whose dark green end has to be between the tunnel's walls) you can start pumping water into the room. If you have set up everything properly, you should have a pump filling up the room with water. The water should flow through the room and out of it at the open side of the room. After having enough muddy ground tiles you can stop the dwarf from operating the pump and deconstruct it (the pump, not the dwarf!) if you like. Given enough time, any remaining water will either flow out of the room or evaporate, at which point you should have some beautiful muddy ground tiles to farm on. | ||
− | + | You should also consider a bridge for the farmers to reach the farming plots. The bridge at the exit point of the water should be long enough so that the water won't flow over it and damp the ground at its far end. You can do without that second bridge though as you can deconstruct the pump after the irrigation. So there is already a passage for the farmers to get to the plots. | |
− | Here's | + | Good luck! Here's a diagram of this method: |

+ | First you need a sufficient source of [[water]]. The best would be a [[brook]] or [[river]], but it is also possible to use a bigger murky pool (it depends on how many fields you want to irrigate). | ||

After that you can place the floodgates and link them to lever 2. To start the irrigation, channel out the last tile to the river / murky pool. Pull the floodgate-lever to fill the reservoirs and pull it again when they are 7/7. Finally pull the hatch cover's lever and release the water to the lower level. |

This reservoir contains 70 units of water (10x7). 9 units of water are lost to the ground of the reservoir (61 left). Roughly 10 units evaporate while spreading (~51). The water should be just enough to cover the whole farm plot and evaporate quickly. | This reservoir contains 70 units of water (10x7). 9 units of water are lost to the ground of the reservoir (61 left).
