Seniority, absolute versus conditional water, and decreed uses for all 78 water rights on record in Broomfield County, taken from the state's own records. Priority dates run from 1863-06-06 to 2020-12-31.
CFS on record: 57.7 absolute · 373.7 conditional. Flow (CFS) and volume (AF) are never added together.
Worth knowing: Broomfield County has about 4.5x 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.
