Drought restrictions and curtailment
Verify notices, priority administration and irrigation scheduling restrictions.
A careful research sequence
Verify notices, priority administration and irrigation scheduling restrictions. For agricultural users, water law is not uniform nationally. Rights may arise from permits, historic appropriations, riparian rules, contracts or groundwater statutes, and the terminology and exceptions differ.
- Identify whether the intended withdrawal is groundwater, surface water, delivered irrigation water, rainwater or reclaimed water.
- Locate the property, well or diversion point on a map and determine whether a district or basin authority has jurisdiction.
- Ask the actual regulator about registration, permit exemptions, allocations, fees, measurement and reporting.
- Check whether drought notices, transfer rules or limitations apply to this source and planned use.
- Keep written permits, meter readings, maps, correspondence and expiration dates in one record.
Questions for an authority
- Does my parcel or diversion point fall within your jurisdiction?
- What is the exact citation and current effective date of the applicable rule?
- Do you distinguish an existing water right from authority to drill or pump?
- Are metering, beneficial-use reports, permit renewals or change applications required?
- Does the activity have a seasonal or emergency restriction?
