Water wheel not working on river

[Sam]

I dug a channel from a river (NOT a brook), assembled a horizontal axle, connected a water wheel and... nothing. It doesn't generate power.

Any ideas what's wrong?

Does it flow anywhere or does the water just sit there?

Make sure that there is no "Floor" on the tiles the waterwheel is on. It has to have freedom of movement in that tile. So, basically, a two-tile depth with nothing but water possible in the tile it's operating on.

Should work in a channel from a brook.
These work even after digging 1 deep, eventhough i've read you need +2

Here's how it looks.

Another pic of both water wheels that don't work.

I cant see a gear assembly between the axles and the wheel. Could be the perspective.
Did you place one ?
It shouldn't be a requirement, but I see no other difference between my working one and yours.

[Sam]

I did not. Just an axle, then a water wheel attached to it. So I need axle, gear, then water wheel??

[pezenwever]

As I said, it should not be a requirement to place a gear assembly between the axles and the wheel, but I do not see anything else different between the pic of my working one and yours
So ¯\_(ツ)_/¯
Try digging another channel perhaps. Dig twice down and finish it to size before you connect it to your stream.

I love this game, but there are some frustrating situations occasionally.

Could be that the water is not considered flowing if it has nowhere to go, you can try to make an exit channel for the water after it has passed the waterwheel, so it creates a loop for the water to enter, go past the waterwheel and then back into the river. The bottom one looks like it should have flowing water, but not sure if hard edges in the water path can decrease the pressure or something like that. Also I think the water that powers waterwheels have to be on the level below the waterwheel, but looks like that's already the case in the pics too. Also around winter time, even before the water visually freezes, sometimes the water stops flowing at least for the purpose of powering waterwheels.

You can have the back single tile on floor tile, only need the "first" two to be open into z-1.

Have a bunch of perpetuum mobile power generation assemblies working that way without any issue, similar to the wiki's design (though I run with two more wheels and additional side channels for continued water flow) https://www.dwarffortresswiki.org/index.php/Water_wheel#Dwarven_Water_Reactor

My bet (have imgur blocked, so can't verify) is on the channel not providing a "flowing" water path as Thai Lizard mentioned.

This is how water looks when its flowing your river does not look like it is https://imgur.com/wyqE4bo

Well, that is a river. Aren't all rivers supposed to be considered flowing?

Any connection to a river on the same z-level used to be considered "flowing" even if you floodgated a dead-end channel, but apparently not in the new version?

Or could be some new bug with water flow calculations.

the texture matters not all rivers waterbodys are flowing i got several lakes also underground at map border but just one has also this texture that shows flowing water.
