This guy is taking level readings to find the best spot for the new dam to take advantage of the natural fall in the land and maximise water collection.
This thing that Graham is peering through, is like a pair of really strong binoculars.
What you can’t see is Anthony, way out in the paddock, holding a measuring stick.
Graham can then read the stick measurements and calculate how the land falls.
Sometimes it’s quite surprising – where you think it is quite low and water lies, can often be one of the highest points! Can you explain that to me?
