Risk: absolute vs conditional

Worth knowing: Dolores County has about 1.7x more acre-feet decreed as conditional than as absolute. Conditional water is decreed on paper but not yet put to beneficial use. A buyer or lender who does not separate the two is valuing a different asset than the one on the ground.
