Dig diversion swales off contour with the highest point in the primary valley and with the lowest point on the primary ridge. On the primary ridge create swales that are on contour to re-hydrate the primary ridge. Multiple diversion swale and swale systems would be put above and below the key-point to simulate the keyline cultivation. this is all speculation but i suspect that this alternative wouldn't work as well in a pasture as keyline cultivation but but would be implemented in more of a woodland system, where a tractor and plow would be harder to maneuver in between established trees
There is an attached file with a picture to help with my explanation.

If you replaced your proposed swale with a ridgepoint dam, you could add some spreader drains for gravity irrigation. the drawing you present is exactly what Yeomans' Keyline Design system suggests for filling dams. If you wanted to fill a series of dams, you might have one diversion drain falling to the next valley over to fill a keypoint dam....

William Wallace wrote:Terracing and keyline irrigation work significantly different from each other, but they can be done together. Since keyline is done off of contour lines, you must terrace first, and then create your keyline contour lines from there.
My first bit of advice is that if you are going to be a mime, you shouldn't talk. Even the tiny ad is nodding:
