A floodgate is a gate which allows the control of the flow of liquids such as Template:L or Template:L. They are operated by Template:Ls such as Template:Ls or Template:Ls which open and close them. When closed they behave like walls, but allow liquids, objects, and Template:L to pass over them when opened.

They can be manufactured from Template:L (at a Template:L), Template:L (at a Template:L), Template:L (at a Template:L), or Template:L (at a Template:L). Once manufactured, they are built in the desired location using the keys b, x.

Colossus in Arena
This image depicts some orthodox and unorthodox uses of floodgates to control the mixing of creatures and liquids in this arena. The gates, shown in-game as X, act as liquid stoppers and Template:L doors.

Uses

Floodgates are used to control the flow of liquid. Because of the Template:L of certain liquids and the Template:L posed by others, floodgates have a wide range of applications in any dwarven settlement.

They are instrumental in controlled Template:L for Template:Ling, or controlled Template:Ling for Template:L Template:L Template:L.

Floodgates also block the flow of liquid on the Z-axis as it is considered a wall when closed. This can be quite useful when built directly below a Template:L as this will allow you to quickly empty the liquid from the floor above without the danger of its Template:L to rummage through your sewer system.

Placement

Floodgates are constructed Template:Lly on a solid, Template:L floor in the 'closed' position (note that this means it is possible for careless dwarves to trap themselves on the wrong side of the gate). Adjacent walls are not necessary. A Template:L must then link up a Template:L or other triggering mechanism to the floodgate. This requires two Template:Ls; the mechanic will haul one mechanism to the trigger, work for awhile, and then haul the other mechanism to the floodgate to complete the task.

To avoid trapping a dwarf on the wrong side of the floodgate it is building, build walls in the spaces you don’t want the dwarf in (b, C, w). Then suspend the build order on those walls. Once the floodgate is built, you can cancel the walls.

Activation

Once the lever is pulled, the floodgate will open. When the lever is pulled again, the floodgate will close. This will destroy (not displace) any liquid occupying the same tile as the floodgate. Objects on the floodgate's tile, however, cannot be destroyed this way - in fact, the floodgate will refuse to close. Any object, everything from Template:Ls to Template:Ls to Template:Ls to scorpion Template:Ls, can jam the floodgate this way. Once the object is removed, however, the floodgate will grind shut by itself.

Magma control

Floodgates will resist magma when closed, just as a constructed Template:L would, but when opened will be destroyed if they are not made from Template:L. The mechanisms used in the construction of the floodgate must also be magma-safe to prevent this.
