− | Dwarves | + | [[Dwarves]] often like to stand on the wrong side of the floodgate they are constructing so that they may conveniently decline any subsequent labor. They'll stand there with their feet propped up on a conveinent rock, twiddling their thumbs until such time as the floodgate is opened mechanically or deconstructed. To avoid this situation you should build something on the tile you ''don't'' want them to stand on, <tt>Suspend</tt> its construction until the floodgate is complete, and <tt>Cancel</tt> its construction when you're finished. |

Once activated, it will take approximately 100 steps for the floodgate to open or close: the same as [[bridge]]s. | Once activated, it will take approximately 100 steps for the floodgate to open or close: the same as [[bridge]]s. | ||

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]] [[farm]]s. Standing water can be used for drinking, or sufficiently rushing water used as a defense against invaders. | 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.

+ | Unlike doors, floodgates can be built directly adjacent to each other; that is, floodgates do not require an adjacent wall. This allows [[channel]]s 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. | ||
