| Summary | 0001376: Presence of saltwater marsh causes mountain brooks/pools to become salty | ||||
| Description | I have a fortess on a 4x4 map with a brook that descends from a mountain terrian in a series of waterfalls. There is an aquifer. The level of the aquifer is slightly below the level of the brook at it enters the map, and well above the level where it exits the map. There are murky pools at various levels on the map. All of these water sources are saltwater. There is no coastal water on the map and the wildlife for the past seven years has been mountain goats and hoary marmots. There was no notification of saltwater at embark, and to my best recollection, no ocean was nearby the site. It was just a site on a brook, split between rock and forest. I generated a small world and emarked on a similar site with a throw-away party. The water there was freshwater. Obviously this does not happen all the time. | ||||
| Additional Information | May be related to http://www.bay12games.com/dwarves/mantisbt/view.php?id=738, where saltwater crocodiles were found far inland. The fortress is the same one I've been playing for the past week or so, and has been uploaded for another bug. | ||||

Might have been a salt-water marsh, and there is some... oddness with salt water - apparently dwarves will drink it in this version, but get a bad thought for contaminants. Might have resulted in the warning being pulled. Edit: Copy your save for that fort, abandon a copy of the save, then check if it was a salt water marsh using the Reclaim function. |
|
|
^^^ Also, while you're doing the reclaim thing, it would be helpful to grab a screenshot of the embark area and post it along the with the world params (which you can export from Legends). |

The Dwarves were not drinking it when the time came to use water as a beverage, which is what tipped me off to it being saltwater. I have plenty of booze for them. Yes, I see now that part of the embark was called saltwater swamp, even though it was "Heavily Forested". It was closer to a sea than I remembered although there was no coastline on the 16x16 area from which I chose the embark. The embark was, however, also mountainous on one half. Should a brook coming down from mountains really be saltwater? How does saltwater rise through several waterfalls? I think at least there should be a warning before embark. http://dffd.wimbli.com/file.php?id=2150 is the fortress. From that you can see the terrain in question. |

I think you've just solved my little mystery from http://www.bay12games.com/dwarves/mantisbt/view.php?id=953. Thanks. :) |

Once in fortress mode all the water is contaminated by salt, even rainwater, as long as you've got a saltwater source anywhere. You don't need to have an ocean tile in your embark area to get a saltwater source. I'm not sure how far inland the salt actually goes, it's based on factors other than distance. I originally suspected aquifers, but after running a few tests that's not it. Seems to be tied to biomes for some reason. If the biome touches a coastline it'll remain salty even several world-map tiles away from the ocean, and systematically contaminate the other biomes in fortress mode. A biome has to be in contact with an ocean tile on the local map to be salty. I have no idea what factors determine where a saltwater swamp ends and a freshwater swamp begins though. (Embarking on a site with both a freshwater swamp and a saltwater swamp gives you only saltwater, by the way.) However, I always get a saltwater warning on a salty biome, regardless of brooks, rivers, aquifers, freshwater biomes or anything else. |

This is a pretty major bug. The only work around is not to embark on a biome which has a single tile touching saltwater unless you want to put a load of work into creating a desalination plant (screw pump plus fully constructed reservoir). You do however get the salt water warning when you try to embark so it's possible to work around but it makes large swathes of generated worlds almost unusable. |

Water pulled from a well is drinkable even if its from a saltwater source. So all you need is a rope, a bucket and a block and you're good to go. |
|
|
I guess the question, then, is: once you have a well, and thus force the dwarves to drink it, does salt water act like fresh water in every possible instance? |
|
|
danaris other than giving dwarves bad thoughts from drinking "water laced with salt", I haven't seen any other effects which differ from fresh water. |
