Reference excerpt

Water rights for the Navajo Nation have been a source of environmental conflict for decades, as Navajo lands have provided energy and water for residents of neighboring states while many of the Navajo do not have electricity or running water in their homes. Beginning in the 1960s, coal mining by Peabody coal at Black Mesa withdrew more than 3 million gallons of water/day from the Navajo aquifer, reducing the number of springs on the reservation. The Navajo Generating Station also consumed about 11 billion gallons of water per year to provide power for the Central Arizona Project that pumps water from Lake Havasu into Arizona. Native American tribes along the Colorado River were left out of the 1922 Colorado River Compact that divided water among the states, forcing tribes to negotiate settlements with the states for water. The Navajo negotiated water settlements with New Mexico and Utah in 2009 and 2020 respectively, but had not reached an agreement with Arizona in 2023. On June 22, 2023, the US Supreme Court ruled in Arizona v. Navajo Nation that the federal government of the United States has no obligation to ensure that the Navajo Nation has access to water. The court ruled that the 1868 treaty establishing the Navajo Reservation reserved necessary water to accomplish the purpose of the Navajo Reservation but did not require the United States to take affirmative steps to secure water for the Tribe. Additionally, environmental crises, such as the 2015 Gold King Mine waste water spill have had lasting impact on the Nation's access to clean water.

Water rights and access The Navajo reservation is the largest Indian reservation in the US with a population of about 175,000 people. In 2023, about one third of residents did not have running water in their homes.

Water rights to the Colorado River are governed by the 1922 Colorado River Compact that divides the water among western states. Indigenous Nations were left out of this agreement, forcing them to negotiate for water from the states. In 1908, the US Supreme Court ruled in Winters vs United States that Native American water rights should have priority over settler claims, because the federal government established those claims when the reservations were formed. Beginning in the 1960s, coal mining by Peabody coal at Black Mesa withdrew more than 3 million gallons of water/day from the Navajo aquifer, reducing the number of springs on the reservation. From 1968 until 2019, the Navajo Generating Station consumed 11 billion gallons of water/year to provide power for the Central Arizona Project, which pumps water from Lake Havasu into Arizona.

New Mexico Water Rights In 2005, the tribe made a water agreement with the state of New Mexico securing some water rights in the San Juan Basin. Congress approved that agreement in 2009, but the tribe lacked pipeline infrastructure to access that water. The San Juan Generating Station’s water reservoir was sold to the U.S. Bureau of Reclamation in 2023 to provide a reliable and sustainable water supply to Navajo homes and businesses. The reservoir was renamed the Frank Chee Willetto Reservoir. The settlement supports a variety of projects and provides federal funding for some of them. The Navajo Nation will receive water allocations in the form of releases from the Navajo Dam. However, New Mexico maintains priority rights and can deplete from the Navajo Reservoir under certain conditions. The agreement also states that Navajo groundwater diversions from the San Juan Basin in New Mexico can be used for purposes in Arizona, and vice versa.

Utah Water Rights In 2020, the tribe completed a water settlement with the state of Utah. The section of the Navajo Nation Indian Reservation that falls in the southeast corner of Utah is home to over 5,000 people. As of 2022, about half of the Navajo households in Utah have indoor plumbing, and those without may have to travel up to 50 miles round trip to get water. The water settlement, named “Navajo Nation Utah Water Rights Settlement” outlines the rights of the Navajo Nation to use water from the Colorado River System in Utah, specifically naming allowable withdrawals and depletions from the San Juan River. The new settlement states that the Navajo Nation can withdraw up to 81,500 acre feet annually from the system. Agreements regarding water rights of the Navajo Nation in Utah also involved allocation of funds to water infrastructure projects. The Infrastructure Investment and Jobs Act, or Bipartisan Infrastructure Law, passed under the Biden Administration in November 2021 awarded $2.5 billion to the Indian Water Rights Completion Fund. Over $200 million of this money was allocated to Navajo Nation water projects under the water rights settlement with the state of Utah.

Arizona Water Rights Settlement In 2023, the tribe still had not completed a settlement with the state of Arizona, and is not receiving their share of Arizona's water under the Colorado River Compact. Arizona has tried to use water access as a way to force the Navajo to make concessions on unrelated issues, and other tribes have also had trouble negotiating water settlements with Arizona.

Arizona v Navajo Nation

The tribe brought a lawsuit against the federal government in 2003, seeking to force the federal government to assess the Nation's water needs and "devise a plan to meet those needs." The states of Nevada, Arizona, and Colorado intervened in the suit to protect their access to water from the Colorado River. In 2021, the 9th U.S. Circuit Court of Appeals ruled that the tribe could force the government to ensure its access to water. The suit was decided by the Supreme Court in 2023 in favor of the states. Justice Brett Kavanaugh wrote the majority opinion, and said that the 1868 Treaty of Bosque Redondo between the Navajo Nation and the federal government did not require that the US government secure water access for the Navajo. Justice Neil Gorsuch wrote the dissenting opinion, and argued that the federal government should identify the water rights that are held for the Navajo Nation and ensure that water had not been misappropriated. The court affirmed the Navajo Nation's right to intervene in lawsuits related to water claims.

Worked examples

Example 1 — a first encounter with Navajo water rights

Start with the simplest possible case. Write down what Navajo water rights claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Navajo water rights before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Navajo water rights ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Navajo water rights

In research: Navajo water rights appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Navajo water rights in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Navajo water rights is common in secondary-school and first-year university syllabi. It links to neighbouring topics Environmental ethics, Environmental justice in the United States, Environmental racism in the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Navajo water rights outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
