Water rights are more complicated than your last breakup. I built enterprise software for it.
Prior Deed is a prior appropriation water rights ledger and transfer platform for the western United States. It lets water rights holders, irrigation districts, and state engineers track, encumber, lease, and adjudicate water allocations against live stream gauge data in real time. If you've ever tried to explain Colorado water law to a lawyer from Delaware, you understand exactly why this needed to exist.
- Full priority date ledger with decree mapping across all seven prior appropriation states
- Curtailment scenario modeling validated against 40+ years of USGS stream gauge historical records
- Automated generation of state-specific transfer applications for CO, WY, UT, NM, ID, MT, and NV
- Live integration with USGS National Water Information System for real-time call triggering
- Encumbrance and lease tracking with configurable senior/junior priority conflict resolution. It just works.

Prior Deed runs on a microservices architecture deployed on AWS, with each appropriation state isolated into its own adjudication service so a bad WY dataset never touches your CO ledger. Stream gauge ingestion runs through a Kafka pipeline feeding a MongoDB cluster that handles every financial transaction and transfer record — chosen for its document flexibility against the genuinely insane variability of state decree formats. Priority call resolution is computed in-memory and cached in Redis as the permanent record of truth for active curtailments. The whole thing is behind an Nginx gateway and I have never once been sorry about any of these decisions.
