Organized into four sections, the twelve chapters of Rivers of Change are concerned with prehistoric Native American societies in eastern North America and their transition from a hunting and gathering way of life to a reliance on food production. Written at different times over a decade, the chapters vary both in length and topical focus. They are joined together, however, by a number of shared “rivers of change.”
Mark Spragg grew up on the oldest dude ranch in Wyoming - a remote spread in the Shoshone National Forest. It is a sublime but unforgiving landscape, a place of unrelenting winds, pitiless blizzards, fierce rivers, and the men who work there have to be tough to survive. Spragg writes lyrically of this world, its animals - horses, bears, elk - and of its people, in particular his parents and John, an old cowboy who becomes the boy's mentor. This is a book about joy - Spragg's writing is miraculous; tough but beautiful, passionate and funny.

Far from being the serene, natural streams of yore, modern rivers have been diverted, dammed, dumped in, and dried up, all in efforts to harness their power for human needs. But these rivers have also undergone environmental change. The old adage says you can’t step in the same river twice, and Ellen Wohl would agree—natural and synthetic change are so rapid on the world’s great waterways that rivers are transforming and disappearing right before our eyes. A World of Rivers explores the confluence of human and environmental change on ten of the great rivers of the world. Ranging from the Murray-Darling in Australia and the Yellow River in China to Central Europe’s Danube and the United States’ Mississippi, the book journeys down the most important rivers in all corners of the globe. Wohl shows us how pollution, such as in the Ganges and in the Ob of Siberia, has affected biodiversity in the water. But rivers are also resilient, and Wohl stresses the importance of conservation and restoration to help reverse the effects of human carelessness and hubris. What all these diverse rivers share is a critical role in shaping surrounding landscapes and biological communities, and Wohl’s book ultimately makes a strong case for the need to steward positive change in the world’s great rivers.
If he was reincarnated today, Captain Meriwether Lewis could retrace the journey that his Lewis & Clark expedition made two centuries ago. Within hours he would shake his head in confusion and surprise. What became of the Missouri, Yellowstone, and Columbia rivers he traveled along? The answers come alive when told by those who live along these waterways. Following Lewis and Clark's route, author Tom Mullen spent five months exploring the Missouri, Yellowstone, and Columbia rivers. This book tells of his surprising discoveries in a landscape peppered by colorful characters, barge pilots, engineers, and biologists, and their determination to improve American rivers. This travelogue is a refreshing blend of quirky history, intriguing stories, and candid conversation from off the beaten trail.
An exhilarating travelogue for a new generation about a journey along Colombia’s Magdalena River, exploring life by the banks of a majestic river now at risk, and how a country recovers from conflict. "Richly observed." —Liesl Schillinger, The New York Times Book Review An American writer of Argentine, Syrian, and Iraqi Jewish descent, Jordan Salama tells the story of the Río Magdalena, nearly one thousand miles long, the heart of Colombia. This is Gabriel García Márquez’s territory—rumor has it Macondo was partly inspired by the port town of Mompox—as much as that of the Middle Eastern immigrants who run fabric stores by its banks. Following the river from its source high in the Andes to its mouth on the Caribbean coast, journeying by boat, bus, and improvised motobalinera, Salama writes against stereotype and toward the rich lives of those he meets. Among them are a canoe builder, biologists who study invasive hippopotamuses, a Queens transplant managing a failing hotel, a jeweler practicing the art of silver filigree, and a traveling librarian whose donkeys, Alfa and Beto, haul books to rural children. Joy, mourning, and humor come together in this astonishing debut, about a country too often seen as only a site of war, and a tale of lively adventure following a legendary river.
The conventional approach to river protection has focused on water quality and maintaining some "minimum" flow that was thought necessary to ensure the viability of a river. In recent years, however, scientific research has underscored the idea that the ecological health of a river system depends not on a minimum amount of water at any one time but on the naturally variable quantity and timing of flows throughout the year. In Rivers for Life, leading water experts Sandra Postel and Brian Richter explain why restoring and preserving more natural river flows are key to sustaining freshwater biodiversity and healthy river systems, and describe innovative policies, scientific approaches, and management reforms for achieving those goals. Sandra Postel and Brian Richter: explain the value of healthy rivers to human and ecosystem health; describe the ecological processes that support river ecosystems and how they have been disrupted by dams, diversions, and other alterations; consider the scientific basis for determining how much water a river needs; examine new management paradigms focused on restoring flow patterns and sustaining ecological health; assess the policy options available for managing rivers and other freshwater systems; explore building blocks for better river governance. Sandra Postel and Brian Richter offer case studies of river management from the United States (the San Pedro, Green, and Missouri), Australia (the Brisbane), and South Africa (the Sabie), along with numerous examples of new and innovative policy approaches that are being implemented in those and other countries. Rivers for Life presents a global perspective on the challenges of managing water for people and nature, with a concise yet comprehensive overview of the relevant science, policy, and management issues. It presents exciting and inspirational information for anyone concerned with water policy, planning and management, river conservation, freshwater biodiversity, or related topics.
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. Developing successful restoration responses are essential. Renewing Our Rivers addresses this need head on with examples of how to design and implement stream-corridor restoration projects. Based on the experiences of seasoned professionals, Renewing Our Rivers provides stream restoration practitioners the main steps to develop successful and viable stream restoration projects that last. Ecologists, geomorphologists, and hydrologists from dryland regions of Australia, Mexico, and the United States share case studies and key lessons learned for successful restoration and renewal of our most vital resource. The aim of this guidebook is to offer essential restoration guidance that allows a start-to-finish overview of what it takes to bring back a damaged stream corridor. Chapters cover planning, such emerging themes as climate change and environmental flow, the nuances of implementing restoration tactics, and monitoring restoration results. Renewing Our Rivers provides community members, educators, students, natural resource practitioners, experts, and scientists broader perspectives on how to move the science of restoration to practical success.
California Rivers and Streams provides a clear and informative overview of the physical and biological processes that shape California's rivers and watersheds. Jeffrey Mount introduces relevant basic principles of hydrology and geomorphology and applies them to an understanding of the differences in character of the state's many rivers. He then builds on this foundation by evaluating the impact on waterways of different land use practices—logging, mining, agriculture, flood control, urbanization, and water supply development. Water may be one of California's most valuable resources, but it is far from being one we control. In spite of channels, levees, lines and dams, the state's rivers still frequently flood, with devastating results. Almost all the rivers in California are dammed or diverted; with the booming population, there will be pressure for more intervention. Mount argues that Californians know little about how their rivers work and, more importantly, how and why land-use practices impact rivers. The forceful reconfiguration and redistribution of the rivers has already brought the state to a critical crossroads. California Rivers and Streams forces us to reevaluate our use of the state's rivers and offers a foundation for participating in the heated debates about their future.
'As fascinating as it is beautifully written' JARED DIAMOND, Pulitzer Prize-winning author of Guns, Germs and Steel Rivers, more than any road, technology or political event, have shaped the course of civilization. Rivers have opened frontiers, defined borders, supported trade, generated energy and fed billions. Most of our greatest cities stand on river banks or deltas, and our quest for mastery has spurred staggering advances in engineering, science and law. Rivers and their topographic divides have shaped the territories of nations and the migration of peoples, and yet - as their resources become ever more precious - can foster cooperation even among enemy states. And though they become increasingly domesticated, they remain a formidable global force: these vast arterial powers promote life but are capable of destroying everything in their path. From ancient Egypt to our growing contemporary metropolises, Rivers of Power reveals why rivers matter so profoundly to human civilization, and how they continue to be indispensable to our societies and wellbeing. 'Takes readers on a tour of the world's great rivers - past, present and future. The result is fascinating, eye-opening, sometimes alarming, and ultimately inspiring' Elizabeth Kolbert, Pulitzer Prize-winning author of The Sixth Extinction 'A tour de force ... From Herodotus musing on the Nile to the dam makers of modern China, this is their story' Fred Pearce, author of When the Rivers Run Dry 'Instructive and entertaining' The Times
The politics of building dams and levees and other structures are just part of the policies determining how American rivers are managed or mismanaged. America's well-being depends upon the health of those rivers and important decisions go beyond just dam-building or dam removal. American rivers are suffering from poor water quality, altered flows, and diminished natural habitat. Current efforts by policymakers to change the ways American rivers are managed range from the removal of dams to the simulation of seasonal flows to the restoration of habitat, all with varying degrees of success. Efforts to restore American rivers are clearly delineated by William Lowry in Dam Politics as he looks at how public policy and rivers interact, examines the physical differences in rivers that affect policies, and analyzes the political differences among the groups that use them. He argues that we are indeed moving into an era of restoration (defined in part as removing dams but also as restoring the water quality, seasonal flows, and natural habitat that existed before structural changes to the rivers), and seeks to understand the political circumstances that affect the degree of restoration. Lowry presents case studies of eight river restoration efforts, including dam removals on the Neuse and Kennebec rivers, simulation of seasonal flows on the Colorado river, and the failed attempt to restore salmon runs on the Snake river. He develops a typology of four different kinds of possible change--dependent on the parties involved and the physical complexity of the river--and then examines the cases using natural historical material along with dozens of interviews with key policymakers. Policy approaches such as conjunctive water management, adaptive management, alternative licensing processes, and water marketing are presented as possible ways of using our rivers more wisely. Dam Politics provides a useful and systematic account of how American waterways are managed and how current policies are changing. American rivers are literally the lifeblood of our nation. Lowry has written a lively and accessible book that makes it clear as a mountain stream that it matters deeply how those rivers are managed.
