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. |

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. | |

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. | ||

An '''underground river''' is, obviously, a river found [[underground]]. They can be located on the embarkation map pre-[[embark]] through use of the [[site finder]], but are usually invisible until revealed by [[exploratory mining]]. When found, the game will pause and special announcement will be seen. | An '''underground river''' is, obviously, a river found [[underground]].

If your site has a cave river, [[tower-cap]]s will automatically start sprouting in underground [[soil]] or [[mud]]dy caverns, because you have already "discovered" the UG river. |

You can tell it's a cave river/pool because of the distinctive aquatic humanoids such as [[Frogman|frogmen]] or [[olm]]s, and the ever-dangerous [[cave crocodile]]s. An exposed underground river cannot be distinguished from the more typical hidden type during site-selection. |

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. |
