NuSlayer: /* Surface Rivers */

== Surface Rivers ==

'''Rivers''' are found on the surface of world maps. They vary in width and depth, some being more wide and some being more deep than others. They often flow through deep canyons or just across the flat surface of a level. On levels with [[cliff]]s, [[waterfall|waterfalls]] may be found.

'''Major rivers, Minor rivers, Streams and Brooks'''''

On the surface of the world you can find four different types of rivers.

*Major Rivers are distinguished by a "=" as opposed to a "-". Some worlds have no Major Rivers so they can be considered quite valuable. Usually they have minor river tributaries and can often feed large [[lake]]s. Major rivers are much wider than regular rivers. Besides this, the difference (if any) between major and minor rivers has yet to be discovered. However major rivers are believed to lower the fps.

*Minor Rivers are dark blue and usually have tributaries of brooks.

*Streams are light blue and often converge with other streams, and have some tributaries of brooks.

*[[Brook]]s are not visible on the region map. They are the smallest flowing body of [[water]] that can be found ingame. Brooks have a special water designation, [[dwarves]] and other units are capable of walking through a brook. Brooks are very common, almost every tile around a stream or larger river will have a brook running through it.

== Underground Rivers ==

An underground river is, obviously, a river found [[underground]]. They are hard to find in the current version of Dwarf Fortress, particularly because you are not guaranteed to have one in your map.

If you are lucky enough to find a cave river, [[tower-cap]]s will start sprouting in [[soil]] or [[mud]]dy caverns. You can use it as the basis of an [[underground forest]] operation.

It is also possible to find cave rivers or pools which are actually visible from the surface - you may even see a few [[tower-cap]]s growing on the surface. This may be rather rare, however, and cannot be spotted from site-selection. (You can tell it's a cave river/pool because of the frogmen or what-have-you in it)

== Other Important Facts ==

*Rivers presumably contain an unlimited amount of water and cannot be drained. They can, however, be dammed if you can *temporarily* drain part of them to 1/7 or less for long enough to install [[floodgate]]s. For some reason, rivers will not overflow floodgates which are blocking them. The water just... stops. This demonstrates one way to drain and dam a river: [http://mkv25.net/dfma/movie-196-draininganddammingamajorriver-i]. Another way to dam a river is to direct a lava flow into it, producing obsidian in the squares where it encounters water.
*Rivers often contain an abundance of [[fishing|fish]], including highly dangerous dwarf-killing fish such as [[carp]], [[pike]], [[longnose gar]], etc.
*See [[water]].
