&lt;div&gt;... but only '''stone''' and metal will hold back magma.&lt;br /&gt;
&lt;br /&gt;
Is this true? In the last version only steel was strong enough to contain magma. --[[User:Mizipzor|Mizipzor]] 15:29, 1 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
: Well, my dolomite floodgates were enough to hold magma. So stone floodgates are capable of holding magma. Dunnoe about wooden ones though. [[User:Noctis|Noctis]] 15:59, 1 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
:Not true. I used stone floodgates all the time with magma in the last version. --[[User:RedKing|RedKing]] 00:52, 2 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
::Perhaps the confusion comes from the fact that you needed steel to bridge over magma --[[User:Moller|Moller]] 02:11, 2 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
:::Alright, the dolomite floodgates that I've mentioned earlier seem to have disappeared, presumably melted away. Thus I'm led to belive that only steel(or better) floodgates are capable of holding magma now. [[User:Noctis|Noctis]] 09:29, 3 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
::::From what I've seen stone floodgates are, at the moment, one use like the steel ones listed in the article...but for different reasons.  A closed stone floodgate will hold back magma indefinitely (probably for the same reason that the normal stone walls hold magma as they do), but once you link  and open it the magma enters the same tile and turns any stone into it's molten counterpart.  This means both your stone floodgate and stone mechanism are turned to slag and eventually lost to the magma forever.  I would bet that the steel floodgates are still there, but forever locked in their open state since your mechanism just got turned to goo and you can no longer select the flood gate from the lever's link menu{{verify}}.  Perhaps [[Bauxite|Bauxite]] might be able to survive the magma {{verify}}, but I need to find some first in order to test that theory.{{version|0.27.169.33b}}   --[[User:TheUbie|TheUbie]] 04:28, 19 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
Interesting note, floodgates seem to take approximately 100 steps to open after activation, from my experimentation. Maybe this could be used in the article somehow? &lt;br /&gt;

== opening and closing ==&lt;br /&gt;
&lt;br /&gt;
do I '''have''' to use a lever to open and close a floodgate? Early on - I have a room next to a river - I want to put a floodgate in the corridor and &amp;quot;bucket fill&amp;quot; a &amp;quot;pond&amp;quot; from the outside.&lt;br /&gt;
&lt;br /&gt;
will this plan work or do I '''need''' a lever?[[User:GarrieIrons|GarrieIrons]] 01:55, 5 January 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
:You need some kind of machine to trigger it, yes. Pressure plates work as well. --[[User:N9103|Edward]] 06:20, 5 January 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
==Construction==&lt;br /&gt;
&lt;br /&gt;
All right... I have a 1-wide channel, with a floodgate &amp;quot;placed&amp;quot; not &amp;quot;built&amp;quot; somewhere along it.&lt;br /&gt;
Access is from a stair to the right.&lt;br /&gt;
No matter if I put the build command closer to the stair, or further away from the stair, the dwarves seem to build the floodgate so that it cuts off their exit! WTF is one to do here? I keep ordering the dwarf that just built the floodgate to remove it so they can get out again.[[User:GarrieIrons|GarrieIrons]] 23:34, 2 February 2008 (EST)&lt;br /&gt;
:Hook it to a mechanism and open it. --[[User:Ikkonoishi|Ikkonoishi]] 00:59, 3 February 2008 (EST)&lt;br /&gt;
::Yeah well when I get a mechanic that is the general plan ;) but right now it's sitting in the middle of a channel while I prey for more immigrants before all of my dwarves die of thirst![[User:GarrieIrons|GarrieIrons]] 01:48, 3 February 2008 (EST)&lt;br /&gt;
:::All right, I have opening and closing floodgates now.[[User:GarrieIrons|GarrieIrons]] 07:45, 5 February 2008 (EST)&lt;br /&gt;
::::Would you mind posting a pic of your setup?  I'm a mite confused on this also....[[User:Holyfool|Holyfool]] 22:38, 3 February 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
==River crossings==&lt;br /&gt;
I can dam/divert a river with floodgates I hope. &lt;br /&gt;
If I dig a channel 1 z-level down, then build a wall, the top is a floor I can walk across. Why isn't the top of a floodgate a floor? it is silly that I have to build a floodgate then a bridge as well, and connect them to the same lever, if I want a floodgate I can walk over. (in real life even a simple drop-board weir - which is pretty mcuh a timber floodgate - can be walked over so that you can put the boards in and out).[[User:GarrieIrons|GarrieIrons]] 07:45, 5 February 2008 (EST)&lt;br /&gt;
:PS. I am diverting my brook by digging a channel through it while it is frozen then building a series of floodgates in the resulting channel. I guess this will work (here's for trying) but how would one divert a river?[[User:GarrieIrons|GarrieIrons]] 07:47, 5 February 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
::Non-freezing? Very difficult to get to work properly, dependent on the terrain of course. Basically, you'd have to dig quite a large pond/lake for the river to fill while scrambling like mad to get those dwarves to install all the floodgates or build the walls before the flow into the lake slows enough for construction-blocking waterlevels to start flowing again. Definitely suggest a stockpile immediately adjacent to the closest entry point to the downstream side of the dam to hopefully avoid a waste of time if only one or two dwarves get their lazy butts over to the work that needs to be done! As for freezing; well, that's always been child's play, and I always wonder why people bother asking someone &amp;quot;if the map they're on freezes,&amp;quot; anytime someone says they need help trying to dam a flow. ;) --[[User:N9103|Edward]] 09:30, 5 February 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
:Well, I have dug a channel in the ice. There are some boulders left behind as well as it seems some ice blocks. I think these will be off to make a pond as ice hauling seems much more efficient to me than bucket hauling?&lt;br /&gt;
:But anyway, the channel is all marked as &amp;quot;blocked&amp;quot; when I try to build floodgates. Will see what it's like when the ice blocks are all gone.[[User:GarrieIrons|GarrieIrons]] 06:40, 6 February 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
==Floodgate swept away ==&lt;br /&gt;
With version 38a I noticed that floodgates can be swept away by molten rock which is pushed by the flowing lava. I don't know if this also happend with earlier versions since this was the first time, because of lack of fule and wood, that I actually used magma.&lt;br /&gt;
Somebody should probably mention in the article that it is advisable to remove rocks from the magma channel to prevent this. [[User:Buckermann|Buckermann]] 11:53, 9 February 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
:The floodgate was verified beforehand to have been built, and not simply dropped and forgotten? --[[User:N9103|Edward]] 07:39, 13 February 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
::I'm quite sure that it was build, and not just dropped. It was even connected to a lever and was working. For a short time at least... And I'm also quite sure that I used Bauxit mechanism for it. [[User:Buckermann|Buckermann]] 09:53, 13 February 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
:::A non-bauxite mech. would be my next point of inquiry, and just to make sure we're not missing the obvious, the floodgate itself was magma-proof? --[[User:N9103|Edward]] 04:14, 14 February 2008 (EST)&lt;br /&gt;
::::Yes, the floodgate too was made of Bauxit, and it is still visible in my magma silo. ([http://i162.photobucket.com/albums/t243/TaBu-NiW/magmachamber.png?t=1203005405 Link to image]) [[User:Buckermann|Buckermann]] 11:11, 14 February 2008 (EST)&lt;br /&gt;
:::::Can you reproduce this? [[User:VengefulDonut|VengefulDonut]] 12:21, 14 February 2008 (EST)&lt;br /&gt;
::::::No. I tried a few times to reproduce this, but never succeeded. Probably I just forgot to use bauxit mechanism the first time. Though, I would have sworn that I did. [[User:Buckermann|Buckermann]] 20:14, 8 March 2008 (EST)&lt;/div&gt;</summary>

::Non-freezing? Very difficult to get to work properly, dependent on the terrain of course. Basically, you'd have to dig quite a large pond/lake for the river to fill while scrambling like mad to get those dwarves to install all the floodgates or build the walls before the flow into the lake slows enough for construction-blocking waterlevels to start flowing again. Definitely suggest a stockpile immediately adjacent to the closest entry point to the downstream side of the dam to hopefully avoid a waste of time if only one or two dwarves get their lazy butts over to the work that needs to be done! As for freezing; well, that's always been child's play, and I always wonder why people bother asking someone &amp;quot;if the map they're on freezes,&amp;quot; anytime someone says they need help trying to dam a flow. ;) --[[User:N9103|Edward]] 09:30, 5 February 2008 (EST)&lt;br /&gt;

:Well, I have dug a channel in the ice. There are some boulders left behind as well as it seems some ice blocks. I think these will be off to make a pond as ice hauling seems much more efficient to me than bucket hauling?&lt;br /&gt;
:But anyway, the channel is all marked as &amp;quot;blocked&amp;quot; when I try to build floodgates. Will see what it's like when the ice blocks are all gone.[[User:GarrieIrons|GarrieIrons]] 06:40, 6 February 2008 (EST)&lt;br /&gt;

==Floodgate swept away ==&lt;br /&gt;
With version 38a I noticed that floodgates can be swept away by molten rock which is pushed by the flowing lava. I don't know if this also happend with earlier versions since this was the first time, because of lack of fule and wood, that I actually used magma.&lt;br /&gt;
Somebody should probably mention in the article that it is advisable to remove rocks from the magma channel to prevent this. [[User:Buckermann|Buckermann]] 11:53, 9 February 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
:The floodgate was verified beforehand to have been built, and not simply dropped and forgotten? --[[User:N9103|Edward]] 07:39, 13 February 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
::I'm quite sure that it was build, and not just dropped. It was even connected to a lever and was working. For a short time at least... And I'm also quite sure that I used Bauxit mechanism for it. [[User:Buckermann|Buckermann]] 09:53, 13 February 2008 (EST)&lt;/div&gt;</summary>

&lt;div&gt;... but only '''stone''' and metal will hold back magma.&lt;br /&gt;
&lt;br /&gt;
Is this true? In the last version only steel was strong enough to contain magma. --[[User:Mizipzor|Mizipzor]] 15:29, 1 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
: Well, my dolomite floodgates were enough to hold magma. So stone floodgates are capable of holding magma. Dunnoe about wooden ones though. [[User:Noctis|Noctis]] 15:59, 1 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
:Not true. I used stone floodgates all the time with magma in the last version. --[[User:RedKing|RedKing]] 00:52, 2 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
::Perhaps the confusion comes from the fact that you needed steel to bridge over magma --[[User:Moller|Moller]] 02:11, 2 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
:::Alright, the dolomite floodgates that I've mentioned earlier seem to have disappeared, presumably melted away. Thus I'm led to belive that only steel(or better) floodgates are capable of holding magma now. [[User:Noctis|Noctis]] 09:29, 3 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
::::From what I've seen stone floodgates are, at the moment, one use like the steel ones listed in the article...but for different reasons.  A closed stone floodgate will hold back magma indefinitely (probably for the same reason that the normal stone walls hold magma as they do), but once you link  and open it the magma enters the same tile and turns any stone into it's molten counterpart.  This means both your stone floodgate and stone mechanism are turned to slag and eventually lost to the magma forever.  I would bet that the steel floodgates are still there, but forever locked in their open state since your mechanism just got turned to goo and you can no longer select the flood gate from the lever's link menu{{verify}}.  Perhaps [[Bauxite|Bauxite]] might be able to survive the magma {{verify}}, but I need to find some first in order to test that theory.{{version|0.27.169.33b}}   --[[User:TheUbie|TheUbie]] 04:28, 19 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
Interesting note, floodgates seem to take approximately 100 steps to open after activation, from my experimentation. Maybe this could be used in the article somehow? &lt;br /&gt;

== opening and closing ==&lt;br /&gt;
&lt;br /&gt;
do I '''have''' to use a lever to open and close a floodgate? Early on - I have a room next to a river - I want to put a floodgate in the corridor and &amp;quot;bucket fill&amp;quot; a &amp;quot;pond&amp;quot; from the outside.&lt;br /&gt;
&lt;br /&gt;
will this plan work or do I '''need''' a lever?[[User:GarrieIrons|GarrieIrons]] 01:55, 5 January 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
:You need some kind of machine to trigger it, yes. Pressure plates work as well. --[[User:N9103|Edward]] 06:20, 5 January 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
==Construction==&lt;br /&gt;
&lt;br /&gt;
All right... I have a 1-wide channel, with a floodgate &amp;quot;placed&amp;quot; not &amp;quot;built&amp;quot; somewhere along it.&lt;br /&gt;
Access is from a stair to the right.&lt;br /&gt;
No matter if I put the build command closer to the stair, or further away from the stair, the dwarves seem to build the floodgate so that it cuts off their exit! WTF is one to do here? I keep ordering the dwarf that just built the floodgate to remove it so they can get out again.[[User:GarrieIrons|GarrieIrons]] 23:34, 2 February 2008 (EST)&lt;br /&gt;
:Hook it to a mechanism and open it. --[[User:Ikkonoishi|Ikkonoishi]] 00:59, 3 February 2008 (EST)&lt;br /&gt;
::Yeah well when I get a mechanic that is the general plan ;) but right now it's sitting in the middle of a channel while I prey for more immigrants before all of my dwarves die of thirst![[User:GarrieIrons|GarrieIrons]] 01:48, 3 February 2008 (EST)&lt;br /&gt;
:::All right, I have opening and closing floodgates now.[[User:GarrieIrons|GarrieIrons]] 07:45, 5 February 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
==River crossings==&lt;br /&gt;
I can dam/divert a river with floodgates I hope. &lt;br /&gt;
If I dig a channel 1 z-level down, then build a wall, the top is a floor I can walk across. Why isn't the top of a floodgate a floor? it is silly that I have to build a floodgate then a bridge as well, and connect them to the same lever, if I want a floodgate I can walk over. (in real life even a simple drop-board weir - which is pretty mcuh a timber floodgate - can be walked over so that you can put the boards in and out).[[User:GarrieIrons|GarrieIrons]] 07:45, 5 February 2008 (EST)&lt;br /&gt;
