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 cliffs, 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 lakes. 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.
  • Brooks 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.
Different sorts of rivers in action

Underground Rivers

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.

Cave spiders may occur near underground rivers. They leave small webs strewn around any nearby areas, which can be collected and woven into silk.

It is also possible (but unusual) to find underground rivers or pools which are automatically visible, as they are exposed to the surface (often due to erosion during world generation) - you may even see a few tower-caps already growing in the area. You can tell it's a cave river/pool because of the distinctive aquatic humanoids such as frogmen or olms, and the ever-dangerous cave crocodiles. An exposed underground river cannot be distinguished from the more typical hidden type during site-selection.

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 floodgates. 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: [1]. Another way to dam a river is to direct a lava flow into it, producing obsidian in the squares where it encounters water.
  • Once dammed, a dry riverbed will refill when it rains, similar to a murky pool.
  • Rivers often contain an abundance of fish, including highly dangerous dwarf-killing fish such as carp, pike, longnose gar, etc.
