Well, I have 30 acres down in the high desert on the UT/NV border in pinion pine and juniper forest. I told the hubby I want a pond down there but he is not going for the idea yet. I have the perfect spot there is a ravene on the property sloped down toward the valley. If we just built up the down hill side, we could line it and fill her up It would be about 100' x 200'.
