The taking, impounding or diversion of water flowing on the public domain from its natural course and the application of the water to some beneficial use personal and exclusive to the appropriator. APPURTENANCE: That which belongs to something, but not immemorially; all those rights, privileges, and improvements which belong to and pass with the transfer of the property, but which are not necessarily a part of the actual property. Appurtenances to real property pass with the real property to which they are appurtenant, unless a contrary intention is manifested. Typical appurtenances are rights-of-way, easements, water rights, and any property improvements.
