Keyline and other dams are shown along with a water release for irrigation. Grazing cattle are also seen. The film then shifts to a yet to be confirmed property where the complete pictorial demonstration of the building of a Keyline (Saddle) Dam takes place. Building a Keyline Dam at a Saddle (A Contour and Functional Plan-Enhanced) 1958 http://issuu.com/gboothy/docs/23._bui... Notes: 1. The saddle itself is the Keypoint and is the exit point for a natural gently-falling dam spillway into the opposite Primary Valley on the other side of the Main Ridge. See Fig. 7 in Chapter 6 (Land Shape) of the above book: http://www.soilandhealth.org/01aglibr... 2. For the final smoothing of the reintroduced top soil over the dam wall itself, the use of a dragged chain between two bulldozers travelling in parallel along the wall crest and the toes of the wall is shown.

Welcome to this 7-part video series that is excerpted from Oregon State University's Online Permaculture Design Certificate Course:
https://workspace.oregonstate.edu/cou...
The Keyline® Plan is a method of land design for soil and water conservation developed by Australian farmer and engineer P.A. Yeomans in the 1950's, and practiced widely throughout Australia ever since. My training in this design system came from Keyline® design's modern day emissary, Darren J. Doherty of the Regrarians (www.regrarians.org). This series is my best attempt to present a simple introduction to the design system, beginning with the very basics: understanding landforms to determine the potentials that each landscape possesses.
There are a lot more design layers to this system then what is presented in this 7-part series, so please treat this as an introduction, and not a comprehensive explanation. I also refer to other videos within this series that are part of Oregon State's Online Permaculture Design Certificate Course and are not publically available, so if you want more depth in this topic and others, please visit our course offerings:
