As adjacent Western states, California and Nevada share similar issues related to drought and limited water resources. Both states are participants in the 1922 Colorado River Compact and the 2003 and 2007 Quantification Settlement Agreements to allocate Colorado River deliveries. Also, about two-thirds of Lake Tahoe lies in California and one-third in Nevada, and the two states have formed a compact to work together on environmental goals for the lake.
Nowhere is the domino effect in Western water policy played out more than on the Colorado River, and specifically when it involves the Lower Basin states of California, Nevada and Arizona. We are seeing that play out now as the three states strive to forge a Drought Contingency Plan. Yet that plan can’t be finalized until Arizona finds a unifying voice between its major water players, an effort you can read more about in the latest in-depth article of Western Water.
Even then, there are some issues to resolve just within California.
It’s high-stakes time in Arizona. The state that depends on the Colorado River to help supply its cities and farms — and is first in line to absorb a shortage — is seeking a unified plan for water supply management to join its Lower Basin neighbors, California and Nevada, in a coordinated plan to preserve water levels in Lake Mead before they run too low.
If the lake’s elevation falls below 1,075 feet above sea level, the secretary of the Interior would declare a shortage and Arizona’s deliveries of Colorado River water would be reduced by 320,000 acre-feet. Arizona says that’s enough to serve about 1 million households in one year.
We explored the lower Colorado River where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to 40 million people in the Southwest across seven states and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs was the focus of this tour.

They are enduring symbols of the vast Mojave Desert, but Joshua trees don’t grow everywhere. Even here in the Grapevine Mesa Joshua Tree Forest, a National Natural Landmark since 1967, you can see where the trees thin out and stop as the land rises sharply to the east.
This issue of Western Water discusses the challenges facing the Colorado River Basin resulting from persistent drought, climate change and an overallocated river, and how water managers and others are trying to face the future.

In 2015, Albuquerque delivered as much water as it had in 1983, despite its population growing by 70 percent. In 2016, Tucson delivered as much water as it had in 1984, despite a 67 percent increase in customer hook-ups. The trend is the same for Phoenix, Las Vegas and Los Angeles, said longtime water policy researcher Gary Woodard, who rattled off these statistics in a recent phone interview.
A federal judge tapped the brakes Thursday but didn’t stop a proposal for a massive and expensive water pipeline to draw underground water from rural valleys along Nevada’s eastern edge to supply the growing Las Vegas metropolitan area.
There was no electricity when Vickie Buchanan’s family came to Diamond Valley in 1958. Nor were there many crops. But there was water, and as early settlers, Vickie’s parents were given priority access under a rule fundamental to Western water law: “first in time, first in right.” A steady flow of farmers followed, planting alfalfa and timothy hay grass in the high-desert soil of the central Nevada valley.

If and when Lake Mead hits 1,075 feet, the government will declare a federal water shortage for the seven states that draw water from the Colorado River, forcing Nevada and the others to limit water use. … Despite the sobering predictions, former Las Vegas water czar Pat Mulroy is confident life will go on in the West.
The “Eagle has landed” moment came at the start of Wednesday’s Southern Nevada Water Authority board meeting, when engineering director Marc Jensen stood to announce what many people in the room were already buzzing about.
Lingering drought has helped push Lake Tahoe’s water level below its natural rim for the first time in five years, cutting off flows into the Truckee River, which has been reduced to a shallow stream as it meanders down the Sierra through Reno.
With an average annual rainfall of only 9 inches, water conservation in Nevada is essential not only in drought years, but every year. This 17-minute video features interviews with key policy-makers who explain how important it is to develop a conservation ethic for this desert state.
In the West, it is not a matter of if a drought will occur, but when. In an effort to develop a drought-proof water supply, many communities are turning to water recycling. Water recycling is reusing treated wastewater for irrigating golf courses, other urban landscapes, some crops, wetlands enhancement, industrial processes and even groundwater recharge. But many people do not understand how water is treated, recycled and reused, causing some to oppose new projects.
A companion to the Truckee River Basin Map poster, this 24×36 inch poster, suitable for framing, explores the Carson River, and its link to the Truckee River. The map includes Lahontan Dam and Reservoir, the Carson Sink, and the farming areas in the basin. Map text discusses the region’s hydrology and geography, the Newlands Project, land and water use within the basin and wetlands. Development of the map was funded by a grant from the U.S. Bureau of Reclamation Mid-Pacific Region, Lahontan Basin Area Office.
This beautiful 24×36 inch poster, suitable for framing, displays the rivers, lakes and reservoirs, irrigated farmland, urban areas and Indian reservations within the Truckee River Basin, including the Newlands Project, Pyramid Lake and Lake Tahoe. Map text explains the issues surrounding the use of the Truckee-Carson rivers, Lake Tahoe water quality improvement efforts, fishery restoration and the effort to reach compromise solutions to many of these issues.
This 24×36 inch poster, suitable for framing, illustrates the water resources available for Nevada cities, agriculture and the environment. It features natural and manmade water resources throughout the state, including the Truckee and Carson rivers, Lake Tahoe, Pyramid Lake and the course of the Colorado River that forms the state’s eastern boundary.
Redesigned in 2017, this beautiful map depicts the seven Western states that share the Colorado River with Mexico. The Colorado River supplies water to nearly 40 million people in Arizona, California, Colorado, Nevada, New Mexico, Utah, Wyoming and the country of Mexico. Text on this beautiful, 24×36-inch map, which is suitable for framing, explains the river’s apportionment, history and the need to adapt its management for urban growth and expected climate change impacts.
The 28-page Layperson’s Guide to Nevada Water provides an overview of the history of water development and use in Nevada. It includes sections on Nevada’s water rights laws, the history of the Truckee and Carson rivers, water supplies for the Las Vegas area, groundwater, water quality, environmental issues and today’s water supply challenges.
The Colorado River provides water to more than 35 million people and 4 million acres of farmland in a region encompassing some 246,000 square miles in the southwestern United States. The 32-page Layperson’s Guide to the Colorado River covers the history of the river’s development; negotiations over division of its water; the items that comprise the Law of the River; and a chronology of significant Colorado River events.
This printed issue of Western Water examines how the various stakeholders have begun working together to meet the planning challenges for the Colorado River Basin, including agreements with Mexico, increased use of conservation and water marketing, and the goal of accomplishing binational environmental restoration and water-sharing programs.
This issue of Western Water examines the challenges facing state, federal and tribal officials and other stakeholders as they work to manage terminal lakes. It includes background information on the formation of these lakes, and overviews of the water quality, habitat and political issues surrounding these distinctive bodies of water. Much of the information in this article originated at the September 2004 StateManagement Issues at Terminal Water Bodies/Closed Basins conference.
