As the population of the greater Las Vegas area grows and the climate warms, the threat of a water shortage looms over southern Nevada. But as Christian S. Harrison demonstrates in All the Water the Law Allows, the threat of shortage arises not from the local environment but from the American legal system, specifically the Law of the River that governs water allocation from the Colorado River. In this political and legal history of the Las Vegas water supply, Harrison focuses on the creation and actions of the Southern Nevada Water Authority (SNWA) to tell a story with profound implications and important lessons for water politics and natural resource policy in the twenty-first century.  In the state with the smallest allocation of the Colorado's water supply, Las Vegas faces the twin challenges of aridity and federal law to obtain water for its ever-expanding population. All the Water the Law Allows describes how the impending threat of shortage in the 1980s compelled the five metropolitan water agencies of greater Las Vegas to unify into a single entity. Harrison relates the circumstances of the SNWA's evolution and reveals how the unification of local, county, and state interests allowed the compact to address regional water policy with greater force and focus than any of its peers in the Colorado River Basin. Most notably, the SNWA has mapped conservation plans that have drastically reduced local water consumption; and, in the interstate realm, it has been at the center of groundbreaking, water-sharing agreements. Yet these achievements do not challenge the fundamental primacy of the Law of the River. If current trends continue and the Basin States are compelled to reassess the river's distribution, the SNWA will be a force and a model for the Basin as a whole.  

At the Precipice explores the question many of us have asked ourselves: What kind of world are we leaving to our children? The realities of climate change consume the media and keep us up at night worrying about the future. But in New Mexico and the larger Southwest, climate change has been silently wreaking havoc: average temperatures in the Upper Rio Grande Basin are increasing at double the global average, super fires like Las Conchas have devastated mountains, and sections of the Rio Grande are drying up. Laura Paskus has tracked the issues of climate change at both the state and federal levels. She shares the frightening truth, both in terms of what is happening in nature and what is not happening to counteract the mounting crisis. She writes, "I wonder about the coming world. Which trees will grow, which birds will have survived. . . . The door to that new world has opened. And there's no going back." And yet our future is not yet determined--or is it?

The Colorado River Basin's importance cannot be overstated. Its living river system supplies water to roughly forty million people, contains Grand Canyon National Park, Bears Ears National Monument, and wide swaths of other public lands, and encompasses ancestral homelands of twenty-nine Native American tribes. John Wesley Powell, a one-armed Civil War veteran, explorer, scientist, and adept federal administrator, articulated a vision for Euro-American colonization of the "Arid Region" that has indelibly shaped the basin--a pattern that looms large not only in western history, but also in contemporary environmental and social policy.   One hundred and fifty years after Powell's epic 1869 Colorado River Exploring Expedition, this volume revisits Powell's vision, examining ts historical character and its relative influence on the Colorado River Basin's cultural and physical landscape in modern times. In three parts, the volume unpacks Powell's ideas on water, public lands, and Native Americans--ideas at once innovative, complex, and contradictory. With an eye toward climate change and a host of related challenges facing the basin, the volume turns to the future, reflecting on how--if at all--Powell's legacy might inform our collective vision as we navigate a new "Great Unknown."

The Colorado River is a crucial resource for a surprisingly large part of the United States, and every gallon that flows down it is owned or claimed by someone. David Owen traces all that water from the Colorado's headwaters to its parched terminus, once a verdant wetland but now a million-acre desert. He takes readers on an adventure downriver, along a labyrinth of waterways, reservoirs, power plants, farms, fracking sites, ghost towns, and RV parks, to the spot near the U.S.-Mexico border where the river runs dry. Water problems in the western United States can seem tantalizingly easy to solve- just turn off the fountains at the Bellagio, stop selling hay to China, ban golf, cut down the almond trees, and kill all the lawyers. But a closer look reveals a vast man-made ecosystem that is far more complex and more interesting than the headlines let on. The story Owen tells in Where the Water Goesis crucial to our future- how a patchwork of engineering marvels, byzantine legal agreements, aging infrastructure, and neighborly cooperation enables life to flourish in the desert, and the disastrous consequences we face when any part of this tenuous system fails. Praise for David Owen's Green Metropolis-

The Green River, the most significant tributary of the Colorado River, runs 730 miles from the glaciers of Wyoming to the desert canyons of Utah. Over its course it meanders through ranches, cities, national parks, endangered fish habitats, and some of the most significant natural gas fields in the country, as it provides water for 33 million people. Stopped up by dams, slaked off by irrigation, and dried up by cities, the Green is crucial, overused, and at risk, now more than ever.   Fights over the river's water, and what's going to happen to it in the future, are longstanding, intractable, and only getting worse as the West gets hotter and drier and more people depend on the river with each passing year. As a former raft guide and an environmental reporter, Heather Hansman knew these fights were happening, but she felt driven to see them from a different perspective--from the river itself. So she set out on a journey, in a one-person inflatable pack raft, to paddle the river from source to confluence and see what the experience might teach her. Mixing lyrical accounts of quiet paddling through breathtaking beauty with nights spent camping solo and lively discussions with farmers, city officials, and other people met along the way, Downriver is the story of that journey, a foray into the present--and future--of water in the West.

Water, the most critical fluid on the planet, is seen as savior, benefactor, and Holy Grail in these fifteen essays on natural and faux oases. Fluvial geologist and former Colorado River guide Rebecca Lawton follows species both human and wild to their watery roots--in warming deserts, near rising Pacific tides, on endangered, tapped-out rivers, and in growing urban ecosystems. Lawton thoroughly and eloquently explores human attitudes toward water in the West, from Twentynine Palms, California, to Sitka, Alaska. A lifelong immersion in all things water forms the author''s deep thinking about living with this critical compound and sometimes dying in it, on it, with too much of it, or for lack of it.The Oasis This Time, the inaugural Waterston Desert Writing Prize winner, is a call for us to evolve toward a sustainable and even spiritual connection to water.

"This book tells three interconnected stories: It chronicles a century of attempts to build dams in Grand Canyon and why those attempts failed. It demonstrates how the National Environmental Policy Act came out of these controversies. Finally, it debunks the myth that the Sierra Club saved Grand Canyon and shows how the club parlayed this perception into the leadership of the modern environmental movement after NEPA became law"--Provided by publisher.

The Ogallala aquifer, a vast underground water reserve extending from South Dakota through Texas, is the product of eons of accumulated glacial melts, ancient Rocky Mountain snowmelts, and rainfall, all percolating slowly through gravel beds hundreds of feet thick. Ogallala: Water for a Dry Land is an environmental history and historical geography that tells the story of human defiance and human commitment within the Ogallala region. It describes the Great Plains' natural resources, the history of settlement and dryland farming, and the remarkable irrigation technologies that have industrialized farming in the region. This newly updated third edition discusses three main issues: long-term drought and its implications, the efforts of several key groundwater management districts to regulate the aquifer, and T. Boone Pickens's failed effort to capture water from the aquifer to supply major Texas urban areas. This edition also describes the fierce independence of Texas ranchers and farmers who reject any governmental or bureaucratic intervention in their use of water, and it updates information about the impact of climate change on the aquifer and agriculture.   Read Char Miller's article on theconversation.com to learn more about the Ogallala Aquifer.

Focusing on the past one hundred years constituting New Mexico's statehood (1912-2012), contributors describe the often convoluted and always intriguing stories that have shaped New Mexico's water past and that will, without doubt, influence its future history.

Originally published in 1987, Water in New Mexico remains one of the most comprehensive studies of a natural resource for any state. It contains material from the earliest pueblo irrigation systems to recent judicial decisions. Clark explores the issues of land-grant water rights, the effects of coal and uranium mining on water quality, the allocation of groundwater, as well as the interstate and federal-state conflicts over land and water.

Rising at 11,750 feet in the Sangre de Cristo range and snaking 926 miles through New Mexico and Texas to the Rio Grande, the Pecos River is one of the most storied waterways in the American West. It is also one of the most troubled. In 1942, the National Resources Planning Board observed that the Pecos River basin "probably presents a greater aggregation of problems associated with land and water use than any other irrigated basin in the Western U.S." In the twenty-first century, the river's problems have only multiplied. Bitter Waters, the first book-length study of the entire Pecos, traces the river's environmental history from the arrival of the first Europeans in the sixteenth century to today. Running clear at its source and turning salty in its middle reach, the Pecos River has served as both a magnet of veneration and an object of scorn.

For sixty million years, the Gila River, longer than the Hudson and the Delaware combined, has shaped the ecology of the Southwest from its source in New Mexico to its confluence with the Colorado River in Arizona. Today, for at least half its length, the Gila is dead, like so many of the West's great rivers, owing to overgrazing, damming, and other practices. This richly documented cautionary tale narrates the Gila's natural and human history. Now updated, McNamee's study traces recent efforts to resuscitate portions of this important riparian corridor.

"To fully understand this river and its past, one must examine many separate pieces of history scattered throughout two nations--seven states within the United States and two within Mexico--and sort through a large amount of scientific data. One needs to be part hydrologist, geologist, economist, sociologist, anthropologist, and historian to fully understand the entire story. Despite this river's narrow size and meager flow, its tale is very large indeed." -From the conclusion The Colorado River is a vital resource to urban and agricultural communities across the Southwest, providing water to 30 million people. Contested Waters tells the river's story-a story of conquest, control, division, and depletion. Beginning in prehistory and continuing into the present day, Contested Waters focuses on three important and often overlooked aspects of the river's use: the role of western water law in its over-allocation, the complexity of power relationships surrounding the river, and the concept of sustainable use and how it has been either ignored or applied in recent times. It is organized in two parts, the first addresses the chronological history of the river and long-term issues, while the second examines in more detail four specific topics: metropolitan perceptions, American Indian water rights, US-Mexico relations over the river, and water marketing issues. Creating a complete picture of the evolution of this crucial yet over-utilized resource, this comprehensive summary will fascinate anyone interested in the Colorado River or the environmental history of the Southwest.

Our rivers are in crisis and the need for river restoration has never been more urgent. Water security and biodiversity indices for all of the world's major rivers have declined due to pollution, diversions, impoundments, fragmented flows, introduced and invasive species, and many other abuses.
