If you are trying to measure it to find out the area, I was going to suggest http://www.acme.com/planimeter/

But, since it's a newer pond, it might not show up on there.

Mine didn't, and I ended up walking along the waters edge with a hand held GPS that had an area calculator imbedded in the software.
