Abstract: A test section for the Pukaki - Ohau Canal has been constructed near footage 25000, just north of Ram Paddock Hill. Four geological formations, the Ostler Formation, Pre Balmoral Outwash, the Balmoral Outwash, all plotted by Hancox (1968) in his fig. II, and a Recent Alluvium are recognized in the area, and their distribution is shown on the accompanying map. Approximate contours are drawn on the interface between the Pre Balmoral Formation and Ostler Formation and the test section of canal is shown to lie in the Pre Balmoral Formation. (auth)
