Editing 40d:Lake

Freshwater '''lakes''' can be found covering vast areas of land on certain world maps.

These lakes have slopes leading into the [[water]], making them ideal for learning how to [[swimmer|swim]].

Lakes are similar to [[Ocean|ocean]]s except that they are freshwater, not saltwater.

== Creating A Large Artificial Lake ==

:''Note: You must have a source of water on your map.''

There are two ways of creating an artificial lake. The easiest way to make one is to [[channel]] into an [[aquifer]]. However, this is dangerous and only one layer deep. The second requires specific circumstances.

"Requirements for a Lake"

*A large, cut off area (e.g: an area over the edge of a [[cliff]], which has no path available to get there).
*A [[brook]] (or larger) that is the same height as the lowest "wall" of this area.
*1 [[Miner]].

Build a 3x3 Downwards [[stair|Staircase]] 1 tile away from your brook. Build [[stair]]cases downwards at least two stories, then start to build a 3x3 [[channel]] towards your intended lake. Four tiles away from the site, build a 3x3 Upwards Staircase, and a Downwards Staircase on the z-level above (this should not come into contact with your [[cliff]] edge or the square behind the cliff face). Mine out a 3x3 passage out of the cliff face, then, when your [[dwarves]] are out of the reservoir, channel over the gap between the brook and the first stairs. This will create a huge [[flood]] that can fill a 8-9 story area (the test lake made was 10 stories high, 891 tiles large, and filled in about 10 - 15 minutes). The reason that this works is because (instead of a normal reservoir with no steps, going directly over the cliff face) the water is replenished every time a 7/7 tile flows out of the stairs, rather than a 1/7, so the water is forced out 7 times more efficiently.
