I don't really know what the bucket is for, I think it is just to siphon through/out of. All you need is a tube full of water, then tape or attatch one end to a board that is beat into the ground (with a reference point on it), and then you could maybe attach the other end to another board, hold it next to the stationary one and transfer the mark accross both boards. Then tape or secure the other end of the hose to the new board. With this done you would essentially have two boards with hoses taped onto them where the water level in each hose is equal to the line. If you wanted to get really creative you should screw a small plywood stand to the bottom of the mobile board. If I were going to do this that is probably how I would do it anyhow, then you could hand the other person a shovel.


This is sort of what I am talking about. Notice my 31337 Paint Skillz.

Carl seems to have a handle on this, and there may be another method for it. But this seems like the easiest way to go about it from where I stand. If you were determined to do it this way...
