have you had your soil analyzed? How much rain do you receive? Are you going to have a well?
My thoughts as well! Looks extremely arid to me, and salty in some nearby areas (unless it snows in July). Glanced over the terrian and didn't see any surface-water - except some swimming pools in the nearby town.
Some tree farming is evident, and the town certainly requires water - so I'm guessing there are wells involved. ?? Otherwise, I saw little evidence of surface-flows. Building the pond is one thing. Filling it with water might be an entirely different challege - based on GE appearances....
