Waterwheels do ''not'' work with [[waterfall]]s, nor in magma — it takes water that is "[[flow]]ing" according to the DF use of the term.

A water wheel occupies 3 adjacent tiles (N-S or E-W axis, no diagonals).  It is the [[Wood#Types|color]] of the <u>first</u> wood selected for it, so you could build a red wheel with one piece of [[goblin-cap]] and two of any other wood.

Dig the V-shaped channel and fill it with water (either from an outside source or by designating it as a [[pond]]).  On the top level, channel out two tiles under each wheel -- the ones under the center of the wheel and the ones by the pump output.  Construct the pump, pumping from the South.  Construct the two water wheels.  Start the pump manually ( {{k|q}}, {{k|Enter}} ) - if there is enough water*, the "reactor" will start immediately and the pump operator will leave.  The water from the north end of the pump will spill over the top-most floor tile, filling that to 7/7 and the two tiles east and west of it to ~5/7, but will not overflow back past the water wheel to the walkway area.  Note that for the upper level, no southern walls are shown as none are needed, unless you don't follow the design and do something to create water pressure.

===Micro Water Reactor===

===Micro Water Reactor===

Channel two adjacent tiles to create a trench, remove the ramp from one trench tile and build a [[Minecart#Track_Stops|track stop]] dumping into the other trench tile. Optionally link a lever to the track stop (to disable and enable the reactor later). Add a minecart to the track stop, build a waterwheel over the trench, and use a pond [[zone]] to fill the ramp tile. The reactor requires 11 units of water for continuous operation; any excess will simply disappear. Once filled, the minecart will dump water into the ramp tile. The water will then flow back to the minecart tile, refilling the minecart and repeating the process endlessly.

Waterwheels require water which is flowing; the game will consider water to be flowing under two circumstances - the first is when water spreads, that is, when deeper water flows to an adjacent tile where the water is shallower. This could be called "gradient flow" because it requires the water be flowing from deeper to shallower. Water which doesn't have a gradient - such as stretches of water which are 7/7 deep - is generally not regarded by the game to be flowing even if water is technically being delivered through those tiles.

It is possible to exploit the game's definition of flowing water and create patches of water which power waterwheels despite the complete absence of actual water movement. When a channel is dug into an aquifer, the channel will sometimes have "natural flow". However, if water is pumped into an aquifer channel, then that channel will then always have "natural flow". This is because water is regarded as disappearing from the map at that point, and the tiles are marked as flowing water, and will power water wheels - even if the pump is removed.

The other way to create water with natural flow is to allow the water to flow off of the map edge (most commonly through a fortification carved into the map edge, although the edge of the map on the surface or in a cavern can also be used). The body of water will then be marked as flowing, even if the map edge is subsequently blocked by a floodgate or raising bridge. This can even be done with finite water sources such as murky pools, for example digging out a channel next to the map edge, building a floodgate to seal the map edge drain, filling the channel with 4/7 water, opening the floodgate, then closing the floodgate and filling it back up to 4/7 water.
