Mid-Atlantic · Regulated RiparianMaryland's water resources include Coastal Plain confined aquifers, Piedmont fractured rock aquifers, and the Chesapeake Bay watershed.
Regulated Riparian (Permit-Based)
A hybrid system where riparian rights exist but significant water uses require state permits.
Key Principles
- •Small domestic uses generally exempt from permitting
- •Major withdrawals (agricultural, commercial, municipal) require state permits
- •Permits typically have terms and conditions including reporting
- •State agencies can limit or revoke permits during shortages
- •Provides more state oversight than pure riparian systems
How to Buy Water Rights in Maryland
- 1Research existing rights. Contact the Maryland 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 Regulated Riparian, 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 Maryland water rights attorney. Water rights transactions are legally complex and state-specific. Always retain a licensed Maryland 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
Permits may be revoked for non-compliance or lapse if not used within the permit term. This is critical to understand before purchasing water rights in Maryland. Always verify recent beneficial use history before closing any transaction.
