A floodgate is an object used to regulate the flow of fluids, such as water and magma.
Placement
Floodgates generally have to be built prior to flooding (obvious for magma, isn't it?) but can still be built at a water level of 1/7.
If there is no roof above a floodgate, and water comes to it from a source with higher elevation, the water can spill over it.
Dwarves often like to stand on the wrong side of the floodgate they are constructing, so that they may conveniently decline any subsequent labor (floodgates are closed by default) until the floodgate is activated. To avoid this situation, you may build a door on the forbidden spot, then forbid the door, then build the floodgate. You will have to deconstruct the door after the floodgate opens, but better a trapped door than a trapped dwarf, as granny says.
Activation
Floodgates have to be linked to levers or pressure plates to allow them to be opened and closed remotely at all. An open floodgate also can be walked through, whereas a closed one can not.
Once activated, it will take approximately 100 steps for the floodgate to open or close: the same as bridges.
Floodgates vs Magma
Closed floodgates of any material will resist magma, much like constructed walls. However, once a magma floodgate is opened, the magma will flow inside it and destroy
- the floodgate itself if it was not made of magma-safe materials.
- the mechanism if it was not made of magma-safe materials (bauxite), thus breaking the open/close trigger.
Uses
A water floodgate connected to a river can be opened to create a shallow pool, then closed, the pool then be drained or allowed to evaporate. The resulting mud can be used for underground farms. Standing water can be used for drinking, or sufficiently rushing water used as a defense against invaders.
A floodgate can also be used to cover fortifications when they are not being used. This will prevent enemies from firing into your fort through the fortifications, and can be useful if your marksdwarfs arrive at the fortification one at a time.
Unlike doors, floodgates can be built directly adjacent to each other; that is, floodgates do not require an adjacent wall. This allows channels wider than two squares to be regulated. This characteristic also permits for the construction of "siege doors", allowing areas wider than two tiles to be sealed off from the enemy. For instance, the three tile wide access point for a Trade Depot within the fortress can be closed down into a chokepoint with floodgates and a lever, giving your marksdwarves more of a chance to shoot invaders.
