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.
