I think the image should be edited... the light blue rivers are streams, not brooks. Brooks are actually invisible on the region map, only visible on local. Only a minor issue though, but it can cause confusion. Lightning4 16:49, 16 November 2007 (EST)

The "cave river" in seed 2967067655 is a short segment enclosed in solid rock, that comes from nowhere and "falls away" into open space at both ends - open space that doesn't extend to the level below. Is this typical of 0.27.169.33? If so, I'll have to put all my cave river plans off to a future version. Kidinnu 09:54, 14 November 2007 (EST)

That sounds very strange. The cave rivers I've seen are sourced from a "mysterious area" and usually either continue off the map or fall off the bottom. They also tend to go through several lowerings of their elevation. Are you sure you fully explored it? VengefulDonut 10:03, 14 November 2007 (EST)

I don't know where this should be mentioned, but there is a huge difference on my machine between FPS on maps with brooks and maps with rivers. I've got a 3.4ghz and 2 gig ram, and my FPS on a map with a river drops to 15-20 right off the bat, where it stays in the high 50's until 30-40 dwarves with only a brook. -- unsigned, but written by Gotthard, according to page history.

I added a bit about temporarily draining and permanently damming rivers and linked to a movie I recorded of doing just that. I think there are ways that would be easier on the dwarves and less micromanagey - one way, perhaps, may be to blast a 3-wide section of the river floor, instead of a 1-wide one, and then build floors in the middle column, and then build floodgates on top of those - that should keep the pesky backflow (which made installing the floodgates so arduous) from interfering with the damming. --SL 00:28, 30 November 2007 (EST)
