you do it like this:
I started digging straight east, placing doors every couple of squares, so my dwarvers could have a chance to escape the flood if I struck the river.
I finally hit it and my dwarf ran to safety until the water receeded.
I then placed a flood gate on the piece of land that caused the flooding to begin with. (if it did not flood your tunnels when you dug it out, it probably wont flood a channel either)
After I set the floodgate to be built, I started digging out my 'farmland'
I looked at the general direction of the river and hoped that it did not suddenly open up directly to the north. Just to be careful, I did not dig the eastern most farm plot completely square.
Once I finished digging one of the plots out:
I proceeded to dig a channel almpost to the entrance of my newly built 'farmland'. I leave one square before the room opens up to place my floodgate.
Then, hopefully I have some mechanic, making mechanisims. I build a room close to all of the action and build at least 2 levers. One for the outer most floodgate(right next to the river) and the last/rest for the inner floodgates, leading to my fields.
Once you have built all of the channels, floodgates, levers, and linked all of the levers to the corresponding floodgates, open up all the floodgates.
(or if you have a bunch of stones/metal/gems etc left on your newly dug fields, and have dwarves set to pick them up;
once all dwarves have left the farming area: open the outer floodgate first, to flood the channels, then the inner floodgate to flood the rest of the rooms.
Or just finish moving the stupid stones!)
here are some more farms:
they do not need to be separate like I have them. If you wanted to, you could place all farms in one huge room (with supports)
