About Water Law in Denver, United States

Water law in Denver is part of Colorado water law, which governs who may use water, how much they may use, and under what conditions. Colorado applies the prior-appropriation doctrine - commonly summarized as "first in time, first in right" - meaning older water rights generally have priority over newer rights when shortages occur. Water law in Denver covers surface water and groundwater, municipal and private uses, transfers and changes of use, water-quality regulations, and the administration and enforcement of rights by state agencies and water courts. Because Denver relies on a mix of municipal supplies, transmountain diversions, groundwater, and storage, legal questions can involve allocation, permitting, adjudication, augmentation for wells, intergovernmental compacts, and environmental obligations.

Why You May Need a Lawyer

Water law is technical, highly fact-specific, and governed by a mix of state statutes, administrative rules, judicial precedents, and interstate compacts. You may need a lawyer in Denver for situations such as:

- Buying or selling property where water rights are involved - to confirm what rights run with the land and to handle deeds and title matters.

- Acquiring, transferring, or leasing water rights - transfers often require water-court approval and careful documentation.

- Filing or defending a water-rights adjudication - disputes over priority, quantity, or diversion practices can end up in water court.

- Changing the use or point of diversion of a water right - most changes require an application to the water court and proof against injury to other users.

- Obtaining permits for wells, irrigation, or construction that affects water supplies - including preparing augmentation plans when necessary.

- Resolving disputes with municipalities, ditch companies, neighbors, or water providers - such disputes can involve easements, ditch maintenance, tolls, or misuse of water.

- Addressing water-quality or regulatory compliance matters under state or federal law - including Clean Water Act and state public-health issues.

- Handling complex matters involving interstate compacts, transmountain diversions, or environmental water rights - which require knowledge of federal and interstate obligations.

Local Laws Overview

This overview highlights the key local and state systems that shape water law in Denver:

- Prior-appropriation system - Colorado allocates water based on priority dates. In times of shortage, senior rights are satisfied before junior rights.

- Water courts - Colorado has a specialized water-court system that handles adjudications, changes of water rights, and related proceedings. Water-court approval is commonly required for transfers or changes.

- Division of Water Resources - The Office of the State Engineer and Division of Water Resources administers water rights, enforces court decrees, issues well permits, and manages streamflow administration.

- Denver Water and local water providers - Denver Water is the primary municipal utility for much of the metro area and holds extensive water rights and infrastructure. Numerous local water districts and ditch companies also hold and administer rights.

- Groundwater regulation - Groundwater is regulated differently from surface water. Denver-Basin aquifers and other groundwater systems often require special permitting, proof of augmentation, or limitations on pumping to protect senior surface rights.

- Augmentation and substitute supply plans - When groundwater pumping would injure senior rights, an augmentation plan or substitute-supply plan may be required to replace depletions to streams or senior users.

- Interstate compacts - Colorado is signatory to compacts such as the Colorado River Compact and the Arkansas River Compact. These compacts influence allocation and operations of transboundary water resources and can affect local rights.

- Water-quality regulation - Federal and state laws address pollution and discharges. Permits and regulatory compliance are handled by agencies such as the state health and environment department. Water-quality compliance is separate from water-rights allocation but often interacts with land use and development projects.

Frequently Asked Questions

What does "prior appropriation" mean and how does it affect my water use?

Prior appropriation is the system Colorado uses to allocate scarce water. Rights are based on a priority date established when water was first put to beneficial use. If there is not enough water, holders of older, or senior, rights are entitled to be served before holders of newer, or junior, rights. Your ability to divert or use water can be limited during shortages depending on the priority of your right.

How can I find out if my property has water rights?

Determining whether a property has water rights requires searching county records, water-court decrees, ditch-company records, and state filings. Deeds sometimes reference water rights, but many rights are separately decreed in water court. A title report, a water-rights search, and consultation with a water attorney or water specialist will clarify what rights attach to the land.

Can I drill a well on my Denver property?

Drilling a well typically requires a permit from the state and may be subject to local ordinances and water-court conditions. In many areas, new wells must demonstrate that pumping will not injure senior surface-water users or must be part of an augmentation plan. The rules differ by basin and aquifer, so consult the Division of Water Resources and a water attorney before drilling.

How do I change the use or location of my water right?

To change the use, point of diversion, or place of use of an existing water right, you generally must file an application in water court. The court examines whether the proposed change will injure other water-rights holders. Applicants often need technical studies and may agree to mitigation such as changed operations or additional storage to prevent injury.

What is an augmentation plan and when is one needed?

An augmentation plan is a legal mechanism used to replace stream depletions caused by new or increased groundwater pumping so senior users are not injured. If pumping depletes streamflow that supports senior surface rights, the well owner may need an augmentation plan approved by a water court or an applicable administrative program.

Who enforces water-rights administration and violations?

The Division of Water Resources, led by the State Engineer, administers water rights, enforces streamflow administration, and can bring actions to stop illegal diversions. Water-court decrees and the courts themselves can also be enforcement venues. Private parties can seek relief in water court for injuries to their rights.

How do municipal supplies like Denver Water relate to private water rights?

Large utilities such as Denver Water hold their own water rights and infrastructure. Municipal suppliers may deliver treated water under service agreements independent from underlying water rights on a property. However, municipal actions - such as buying and transferring agricultural rights for municipal use - can change regional water availability and local priorities. Property buyers should understand whether their water comes from a utility connection or a historic on-site right.

What are the key differences between water-rights matters and water-quality issues?

Water-rights law controls who may use water and how much they may use. Water-quality law controls the condition of water and regulates pollution and discharges. They are separate legal tracks but often interact - for example, a contaminated water source may affect lawful use, and permits for discharges may include conditions that influence water availability for certain uses.

What happens during a drought - can I be shut off?

During droughts, water administration follows priority. Senior rights continue to be fulfilled before junior rights, and curtailment orders can require junior users to stop or reduce diversions. Municipal utilities may impose conservation measures, but those who hold senior, decreed rights may still get water while junior users may face restrictions.

How long does a water-court case or change-of-use proceeding typically take?

Water-court proceedings can take many months to several years depending on complexity, the need for technical studies, the number of objectors, and court backlog. Simple uncontested changes may be faster, but contested matters or those requiring environmental analyses and engineering studies will take longer. Expect to plan for a multi-month to multi-year timeline for substantive water-rights changes.

Next Steps

If you need legal assistance with a water-law matter in Denver, consider this forward plan:

- Gather documentation - deeds, prior water-rights paperwork, well logs, tax records, title reports, ditch-company papers, and any permit or correspondence from state agencies.

- Identify the issue - clarify whether the matter concerns rights acquisition, transfer, well permitting, augmentation, enforcement, contamination, or regulatory compliance.

- Consult a specialized water attorney - look for attorneys with Colorado water law experience, water-court practice, and familiarity with the Denver-Basin and South Platte systems.

- Consider technical experts - hydrogeologists, engineers, and water-resource consultants can produce the studies and modeling often required for filings or litigation.

- Contact relevant agencies early - a preliminary inquiry with the Division of Water Resources, Denver Water, or the local water district can clarify permit requirements and administrative options.

- Plan for time and cost - water matters are often time-consuming and require court filings, surveys, and technical reports. Request an expected timeline and budget estimate from your attorney.

- Explore alternative dispute resolution - mediation or negotiated settlement with other water users or ditch companies can be faster and less costly than litigation.

- Keep careful records and act promptly - missing a permit requirement or failing to file in water court can foreclose options. Prompt, informed action improves the chance of a favorable outcome.

Starting with clear documentation, the right legal and technical advisors, and an understanding of Colorado's prior-appropriation system will help you navigate water-law issues in Denver more effectively.
