It has been disguised by being overlooked and by our education which ignores it. Even if you look at a primary valley in the cleared countryside you will not see the Keyline, unless a farmer has marked it with a water channel or has disclosed it with the water line of a farm dam. But you may discern the. By accident or by instincts developed from long and intimate association with land, a few farming families have improved and strengthened the primary valleys. Then the water which falls as rain on all the ridges, which occupy so.
Water flows from farming land in the same efficient manner as it does from the natural landscapes.
Therefore much water passes without being used effectively in the landscape. The natural landscapes had come to terms with the water. A state of balance existed which was in accord with the amount of water available to the land. When the man-made landscapes of farm and city were imposed on those of nature, the balance of the association of land and water was changed. The design which achieves the optimum control and beneficial use of water for the development of high fertility, efficiency and balance for the farmscape, will be the logical design for townscape and cityscape and for all the special purposes landscapes of man.
