When purchasing agricultural land, most buyers focus on soil quality, location, and acreage. But there's one critical factor that can make or break your investment: water rights. Without secure access to water, even the most fertile farmland becomes worthless. Water rights determine your ability to irrigate crops, sustain livestock, and maintain profitable operations. These legal entitlements are often complex, vary significantly by location, and can dramatically impact both the value and usability of agricultural property. This guide will help you navigate the intricate world of water rights and make informed decisions when buying agricultural land with irrigation assets.

What are Water Rights?
Water rights are legal entitlements that grant individuals, organizations, or entities the authority to use water from a specific source for a designated purpose. These rights can apply to surface water, such as rivers, lakes, and streams, as well as groundwater accessed through wells.
Why are Water Rights Important?
Water rights are essential because they establish a legal framework for the allocation and use of water resources, ensuring equitable access and sustainable management. For agricultural communities, water rights are critical for maintaining consistent irrigation, which is vital for crop production and food security. Agriculture consumes approximately 80% of the United States' freshwater resources, making water access the lifeblood of farming operations. Climate change, growing populations, and increased competition for water resources have made secure water rights more valuable than ever.
Water rights differ significantly between the eastern and western states. In the arid West, where water is a scarce resource, regulations are far stricter to ensure its careful management and distribution. Consider this: agricultural land with guaranteed water rights can sell for 2-3 times more than similar property without water access. In drought-prone regions like California's Central Valley, water rights can account for up to 50% of a property's total value.
Types of Water Rights
Like mineral rights, water rights can either be tied to a property or separated from it. This raises an important question: do you hold water rights on your property? The specifics of water rights depend on regional laws and regulations, which dictate how water can be allocated, used, and transferred. Typically, water rights fall into two primary systems: riparian rights, where access is tied to land ownership adjacent to a water source, and prior appropriation, where rights are based on a "first in time, first in right" principle. Understanding these distinctions is crucial for those involved in agriculture, as water rights directly influence the ability to irrigate crops, support livestock, and sustain long-term agricultural productivity.
Riparian Water Rights: Riparian rights apply to properties next to natural water sources like rivers, streams, or lakes. If your land borders water, you may have the right to use it. These rights allow "reasonable use" but not unlimited consumption, and they may require sharing during shortages. Riparian rights are common in eastern states with more abundant water.
Appropriative Water Rights: Appropriative rights, or "prior appropriation" rights, follow a "first in time, first in right" rule. The earlier someone uses water beneficially, the higher their priority during shortages. These rights are tied to the date of first use and can be sold separately from the land. To keep the right, the water must be actively used, following "use it or lose it" rules. Western states primarily use this system due to the region's dry climate and the need to transport water for mining and agriculture.
Groundwater Rights: Groundwater rights govern the use of water from underground aquifers and vary widely across states under different legal doctrines. The Absolute Ownership Doctrine allows unlimited groundwater use, while the Correlative Rights Doctrine allocates a "fair share" based on land size. The Prior Appropriation Doctrine operates on a "first-come, first-served" basis. These laws aim to balance extraction, promote responsible use, and reduce conflicts among landowners, farmers, and communities.
Legal Frameworks for Water Rights
Water rights involve complex legal and regulatory frameworks that vary significantly by location, depending on factors such as local laws, historical usage, and availability of water resources. These frameworks determine who can use water, how much can be used, and for what purposes, often balancing agriculture, industry, and residential needs.
State Water Laws: Research your state's water laws and regulatory framework. The type of water rights system that applies, along with permit requirements for water use, are key considerations. Additionally, understanding transfer and change procedures, monitoring and reporting obligations, as well as enforcement mechanisms and penalties, is essential for proper water management.
Federal Regulations: Federal laws may also apply, including the Endangered Species Act, which may restrict water use to protect fish and wildlife, the Clean Water Act, which regulates water quality and discharge, and the National Environmental Policy Act, which requires an environmental review for major water projects.
Local Regulations: Don't overlook local regulations, such as county groundwater ordinances, municipal water restrictions, irrigation district rules and assessments, and special district regulations.
Environmental Compliance: Modern water use is increasingly subject to environmental scrutiny, with various potential restrictions to consider. These include stream flow requirements to protect fish habitats, wetland protection regulations, groundwater sustainability requirements, and water quality standards with ongoing monitoring.
How Water Rights Impact Agricultural Land Value
Water rights play a crucial role in determining both the immediate usability and long-term value of agricultural land, and there are many factors that affect the value of water rights. Farmland with reliable natural water sources, such as rivers, lakes, or groundwater, often commands a higher market value due to its dependable water supply. Conversely, properties lacking natural water access typically require expensive irrigation systems, making them less appealing to potential buyers. In regions where water rights are tightly regulated, legal access to water can significantly impact land value. Restrictions or limitations on water usage can greatly diminish the land’s desirability and market potential.
How Irrigation Systems Impact Agricultural Land Value
An existing irrigation system can significantly enhance the value of agricultural land by minimizing the need for additional water management investments. Well-maintained infrastructure, such as drip systems or center pivot irrigation, boosts farmland productivity, often driving up its market value. In contrast, land lacking irrigation systems may come at a lower upfront cost but requires buyers to account for the additional expense of installing such infrastructure.
Water Rights Due Diligence: Steps to Take Before Buying Agricultural Land
Before purchasing agricultural land, conduct thorough due diligence on all water rights and irrigation assets.
1) Determine Water Needs
Understanding your water needs is a crucial first step when buying agricultural land. Begin by assessing the specific crops you plan to grow or the type of livestock you will raise, as each has distinct water requirements.
Climate: Hot, dry, or windy climates increase evaporation, meaning crops need more water. Be sure to research the average precipitation and temperature in the area.
Soil Type: Soil types vary in their water needs to stay productive. Sandy soils, for instance, drain quickly and retain less moisture compared to loamy or clay soils. As a result, they require more frequent watering to maintain optimal conditions.
Crop Type: Crops generally require around 1 inch of water per week, though this can vary greatly depending on several factors. For instance, leafy greens tend to demand more water compared to root vegetables.
2) Examine the Property's Water Sources
Assess any wells or surface water sources on the property and evaluate their production rates and water quality. Review recent water delivery records to gain a clear understanding of actual water availability compared to documented water rights. Keep in mind that during drought years, even holders of senior water rights may face reduced allocations.
Key questions to consider when examining a property's water resources include:
How much water was actually delivered in recent years?
Were there any curtailments or shortages?
What's the reliability of the water source?
Are there competing demands on the water supply?
3) Verify Legal Documentation
Water rights don't always transfer automatically with land ownership. It's essential to review the title and deed to determine whether the water rights were included in the sale or reserved by the seller. Some water rights may require separate documentation or regulatory approval. To ensure clarity, begin by thoroughly reviewing all relevant water rights documentation, including:
Certificates of appropriation
Groundwater permits
Irrigation district memberships
Historical water use records
Any water rights leases or agreements
For comprehensive guidance, consult an attorney to professionally review all water-related documents, verify the chain of title, and clarify any usage restrictions. Water rights attorneys can help with tasks like reviewing documentation, conducting title searches, negotiating transfers, resolving disputes, and ensuring regulatory compliance. Look for attorneys experienced in your state’s water laws and agricultural water use for effective guidance.
4) Research Water Right Priority and History
Water rights differ from state to state, and many states offer resources to help you navigate them. You can start by reaching out to the state’s water resources agency or reviewing county records and information from local ditch companies to investigate the priority date, historical use of water rights, water availability studies, and any pending applications or protests. In regards to priority dates, earlier priority dates offer stronger protection during times of scarcity. Be sure to identify any gaps in beneficial use that may have led to a lapse in rights.
5) Consider Working with Professionals
Experienced agricultural land brokers are well-versed in local water rights issues and offer valuable expertise. They can identify properties with secure water rights, evaluate these rights as part of property valuation, connect you with relevant experts and professionals, and navigate complex transactions involving multiple water rights. Choosing brokers with proven experience in agricultural land and water rights transactions is essential to ensure a smooth and successful process.
Evaluating Irrigation Infrastructure When Buying Farmland
Water rights mean little without proper infrastructure to deliver water to crops. Carefully assess all irrigation systems and related assets.
1) Understand Irrigation System Types
Water for irrigation can come from various sources, including direct diversions from rivers or streams, canal or ditch delivery through irrigation districts, groundwater pumping from on-site wells, and stored water from reservoirs or ponds. Each delivery method has different reliability, costs, and operational requirements. First, you must understand the type of irrigation system present on the property to determine if it aligns with your needs. Different irrigation systems have varying efficiency levels, maintenance requirements, and operational costs. The three main irrigation system types are flood irrigation, sprinkler systems, and drip irrigation systems.
Flood Irrigation: Traditional method using gravity to distribute water across fields. Lower upfront costs but higher water usage and labor requirements.
Sprinkler Systems: More efficient than flood irrigation, with better water distribution control. Includes wheel lines, center pivots, and solid set systems.
Drip Irrigation: Most water-efficient method, delivering water directly to plant roots. Higher initial investment but significant water and labor savings.
Ensure the irrigation system is capable of providing sufficient water to support your planned crops and farming operations, especially in arid or drought-prone conditions. Consider factors such as water availability, soil type, and the specific needs of your crops to ensure consistent and efficient irrigation. Proper planning and system design can make a significant difference in maintaining healthy yields and sustainable farming practices.
2) Assess the Condition of the Irrigation Infrastructure
Next, evaluate the current condition of irrigation infrastructure. The key factors to consider include the age and condition of pumps, motors, and wells, as well as the integrity and capacity of pipelines. Automation and control systems play a crucial role, along with the condition of storage facilities like ponds or reservoirs. Additionally, filtration and water treatment equipment are essential components that require careful evaluation. Factor replacement and upgrade costs into your purchase decision. Modern, efficient irrigation systems can significantly improve water use efficiency and reduce operational costs..
Hire a professional inspector or technical expert to thoroughly evaluate the soil, irrigation systems, and drainage on the property- they can also help you assess the costs for any required repairs, upgrades, or additions to the irrigation system and supporting infrastructure. Keep in mind that well-maintained irrigation systems and infrastructure not only boost the land's value but also contribute significantly to its long-term productivity.
Is Agricultural Land a Good Investment?
Investing in agricultural land offers a stable, long-term, and tangible asset for those seeking diversification, though it comes with its own set of risks and demands thoughtful evaluation. With the potential for both appreciation and dual income streams, like rental payments and capital gains, it has become an attractive choice for a wide range of investors, including high-profile names like Bill Gates. In fact, some of the largest landowners in the U.S. are agricultural land investors.
Agricultural land can be a great investment, as long as you conduct comprehensive due diligence. Careful evaluation of the property ensures that potential risks are identified and mitigated, leading to a more informed and successful investment. Water rights and the availability of a suitable irrigation system are just one of the factors to consider when buying farmland.
