How to Buy Water Rights in Ohio
- 1Research existing rights. Contact the Ohio state water resources department to look up water rights records in the area of interest. Most western states maintain searchable public records.
- 2Verify priority date and quantity. Under Reasonable Use, the priority date determines seniority and therefore the value and reliability of the right during shortages.
- 3Conduct due diligence. Verify historical beneficial use, check for forfeiture risk, and confirm the right is current with the state agency.
- 4Hire a Ohio water rights attorney. Water rights transactions are legally complex and state-specific. Always retain a licensed Ohio water rights attorney before closing.
- 5File transfer with the state. Most transfers require state approval. Change of ownership, point of diversion, or use typically require formal filings.
Forfeiture & Non-Use Rules
Rights generally persist but can be restricted if use becomes unreasonable relative to other users. This is critical to understand before purchasing water rights in Ohio. Always verify recent beneficial use history before closing any transaction.
