from the book:

The film opens with sweeping views of Yobarnie and Nevallan,
North Richmond NSW. 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._building_a_keyline_dam_at_a_sad
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/01aglibrary/010126yeomansii/010126ch6.html
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.
