THE DRAINS OF KEYLINE

 

   Upper: A large water conservation or feeder drain formed with a 100 horse-power bulldozer. It was next trimmed with farm equipment and sown with pasture grasses and superphosphate. After heavy rainfall it transported into a dam a large volume of water flowing twelve inches deep ("Kencarley", Orange).

   Middle: A recently formed water conservation or feeder drain of the size and section suitable to transfer the run-off rainfall to a farm dam from a catchment area of 50 acres ("Kencarley").

   The smallest drain in Keyline is the irrigation drain (lower picture). The drain stops are left in the irrigation drain after a watering, so that possible heavy runoff rainfall will not be concentrated, but distributed evenly for the benefit of all the area ("Yobarnie", North Richmond).
