I used to assume that if a farm sold with 'water rights included,' the paperwork was clean. Dead wrong. When I helped my nephew evaluate a 120-acre irrigated parcel near Delta, the listing showed senior adjudicated rights attached to the property. Sounded solid. But when we pulled the actual decrees and traced the point of diversion through the state's WRIS database, two of the three rights hadn't been used beneficially in over a decade. In Colorado, abandonment is real and it moves fast. Those rights were effectively vapor. The seller wasn't lying — they just hadn't looked hard enough themselves. We renegotiated the price based on the actual irrigable acreage the surviving right could support, not the full listed acreage. The deal still closed, but at a meaningfully lower number. If you're buying irrigated ground anywhere under prior appropriation, pull the decree, check the diversion records, and confirm beneficial use history before your inspection period closes — not after. Has anyone else caught abandonment risk during due diligence that the seller was genuinely unaware of?
