Then off my own bat I did a 2 lot subdivision here of my 30 acre Australian property. Which involved designing a 400 metre driveway with 4 culverts etc. As part of this process I was required to make my three dams smaller to meet the required 0.75megalitre per lot as part of the development approval conditions. So I filled in one smallish dam and was able to purchase a water entitlement for the remaining two dams so that I didn't have to do any earthworks like lowering the spillways etc. They are not big dams but are a good size for the two fifteen acre blocks which now have a dam in each block. They are about 2.5 megalitres each plus or minus. After a quick chat to the New South Wales Office of Water I learned that I am allowed to do silt removal etc to maintain the water entitlement for which I paid a small fortune. As you can imagine I am not allowed to make it any bigger than the 2.5 megalitres. So now the fun begins. I need to survey it to see if I have more or less than the 2.5 megalitres. Has anyone done any farm dam surveys with the water in them? I have never done any Hydro surveys before and my personal equipment I have at my disposal is a flat-bottom canoe, a hundred metre tape, an old analogue theodolite, a 5metre staff. ranging rods. I'm sure there is a cartoon in there somewhere. Jokes aside. I can borrow the Topcon GR3 GPS set up from work or the Topcon robotic total station. But I might just end up setting up a perimeter grid which is about 60m x 60m on the aerial imagery. Then take depth readings along the knotted rope etc. I would love to hear your ideas and stories if there are any. </span></p></div>
