Out in the western United States you may well not own below your surface soil, you may well not own your mineral rights, you may well not own your water rights and you may well not even own the rain that falls upon your land. Check your deed and your state laws.
This. I got roped into a sales presentation one time in Las Vegas where they were trying to sell land in some no-name town that supposedly had an aquifer under it and the land was going to be very valuable very soon. The minute I mentioned mineral rights the sales team whisked me out of there so fast it took my hat 5 minutes to catch up. Clearly the deal was not actually going to include the rights to the water, if any, and they didn't want me anywhere near any of the other victims^H^H^H^H^H^H customers.
