Do not infer a usable or transferable water right from title, a listing, a stream, a well or historic use. The Civil and Commercial Code places broad categories of water in the public domain and subjects even private waters to public-interest controls; official federal guidance says each province and CABA regulate use within their jurisdiction. Identify the exact source, province, competent authority, holder, purpose, location, quantity, term, transfer path and works before assigning productive value.
The first decision is jurisdiction, not SIARH
Argentina's federal and basin information layers can describe water context, but they do not replace the competent authority's legal file. Law 26.438 recognizes COHIFE as a federal coordination body while respecting provincial original control over water resources. Current national guidance likewise states that each province and CABA has its own rules. This guide therefore does not treat SIARH, a map layer or a basin organization as a national water-rights registry.
Separate six evidence questions
- Source: surface water, groundwater, spring, canal, network or stored supply.
- Authority: competent province, local body and, where relevant, interjurisdictional basin entity.
- Legal file: permit, concession, registration, user roll, restriction or unresolved status.
- Operational scope: named holder, parcel or coordinates, purpose, quantity, term, fees and transfer or change-of-use path.
- Works: well, intake, pump, canal, reservoir, easement, power supply and environmental or construction permissions.
- Physical evidence: actual yield, seasonality, reliability and laboratory-tested quality.
Productive use must be tested against the file
A seller may describe water as suitable for irrigation, livestock, household supply or tourism. Those are proposed uses, not permissions or capacity findings. Ask the competent authority and independent technical advisers whether the current file covers that user, source, location, purpose and quantity; whether a transfer or new application is needed; and whether the works and environmental requirements are compatible with the project.
A fail-closed buyer sequence
- Fix the parcel, coordinates, province and every claimed water source.
- Identify the competent water authority and any basin body without confusing coordination with permitting authority.
- Request current authority evidence and reconcile holder, purpose, location, quantity, term, debts, restrictions and works.
- Record absent, expired, mismatched or pending evidence as unresolved; historic use is not a substitute.
- Test yield and quality independently for the intended use and season.
- Make the contract and payment path reflect the actual unresolved approvals and technical conditions, as advised by the responsible Argentine professionals.
Frequently asked questions
Does land title prove a right to use water?
No national answer should be inferred from the deed alone. The source, jurisdiction, local rules, authority file and exact use need separate review.
Does a well, canal or stream prove usable water?
No. Presence, legal authority, quantity, allowed purpose, infrastructure and quality are different evidence states.
Can a national map or basin page clear a parcel?
No. It may provide context. Parcel-specific authority comes from the competent jurisdiction and current evidence.
Can productive value be estimated before the water file is clear?
Treat water-dependent productive value as conditional until legal availability, physical yield, quality, works and intended use have been independently reconciled.
