The Great Lakes are the largest collection of fresh surface water on earth, and more than 40 million Americans and Canadians live in their basin. Will we divert water from the Great Lakes, causing them to end up like Central Asia's Aral Sea, which has lost 90 percent of its surface area and 75 percent of its volume since 1960? Or will we come to see that unregulated water withdrawals are ultimately catastrophic? Peter Annin writes a fast-paced account of the people and stories behind these upcoming battles. Destined to be the definitive story for the general public as well as policymakers, The Great Lakes Water Wars is a balanced, comprehensive look behind the scenes at the conflicts and compromises that are the past-and future-of this unique resource.
Water quality concerns are not new to the Great Lakes. They emerged early in the 20th century, in 1909, and matured in 1972 and 1978. They remain a prominent part of today's conflicted politics and advancing industrial growth. The Great Lakes Water Quality Agreement, under the Boundary Waters Treaty of 1909, became a model to the world for environmental management across an international boundary. Evolution of the Great Lakes Water Quality Agreement recounts this historic binational relationship, an agreement intended to protect the fragile Great Lakes. One strength of the agreement is its flexibility, which includes a requirement for periodic review that allows modification as problems are solved, conditions change, or scientific research reveals new problems. The first progress was made in the 1970s in the area of eutrophication, the process by which lakes gradually age, which normally takes thousands of years to progress, but is accelerated by modern water pollution. The binational agreement led to the successful lowering of phosphorus levels that saved Lake Erie and prevented accelerated eutrophication in the rest of the Great Lakes ecosystem. Another major success at the time was the identification and lowering of the levels of toxic contaminants that cause major threats to human and wildlife health, from accumulating PCBs and other persistent organic pollutants
This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.

"Lake ecosystems are known to be valid sentinels for current climate changes and anthropogenic pressure because they provide indicators of these impacts either directly or indirectly through the influence of climate and human activity on their catchments. Among these indicators, to name just a few, are water temperature, dissolved organic carbon, nutrients and metals, phyto- and zooplankton composition as well as population and biodiversity of crustacea, mollusks and fish. The advantages of using lakes as tracers of climatic changes and anthropogenic impacts on aquatic ecosystems are multiple. Lake ecosystems are well constrained, confined and are studied in a sustained fashion; lakes respond directly to climate change and local and global pollution via incorporating the effects of these impacts occurring within the catchment; lakes integrate responses over time, and thus allow to avoid the random or unique single-time effects. Finally, lakes of various sizes are distributed worldwide and, as such, can act as sentinels across various climatic conditions while exhibiting different degrees of vulnerability to external pressure depending on their size and specific location capturing different aspects of climate change (e.g., changing precipitation regime, heat waves, permafrost thaw, invasion of new species, local and global (dispersed) pollution). However, the majority of published studies on lakes in the boreal and subarctic zone deal with Western and Northern Europe and Northern America, with quite limited information on lakes in the NW Russia. This book is intended to partially fill this gap by presenting 13 chapters describing the hydrology, hydrochemistry and hydrobiology of various lakes located in the NW European Russia, from the Finland border in the West to the Ural Mountains in the East. The thirteen chapters of the book, written by the experts in the field of biogeochemistry, limnology and zoology cover full limnetic ecosystems, from lake physical characteristics to lake water chemistry, microbiology, phytoplankton and zooplankton population, Crustacea, mollusks and fish. A multidisciplinary approach across wide geographical zones, comprising both small and large lakes of the Russian Subarctic, presented in this book, will be interesting for a large community of scholars, students, and researchers from academic and private organizations"--
This beautifully written book weaves reflections on anthropological fieldwork together with evocative meditations on a spectacular landscape as it takes us to the remote indigenous villages on the shore of Lake Titicaca, high in the Peruvian Andes. Ben Orlove brings alive the fishermen, reed cutters, boat builders, and families of this isolated region, and describes the role that Lake Titicaca has played in their culture. He describes the landscapes and rhythms of life in the Andean highlands as he considers the intrusions of modern technology and economic demands in the region. Lines in the Water tells a local version of events that are taking place around the world, but with an unusual outcome: people here have found ways to maintain their cultural autonomy and to protect their fragile mountain environment. The Peruvian highlanders have confronted the pressures of modern culture with remarkable vitality. They use improved boats and gear and sell fish to new markets but have fiercely opposed efforts to strip them of their indigenous traditions. They have retained their customary practice of limiting the amount of fishing and have continued to pass cultural knowledge from one generation to the next--practices that have prevented the ecological crises that have followed commercialization of small-scale fisheries around the world. This book--at once a memoir and an ethnography--is a personal and compelling account of a research experience as well as an elegantly written treatise on themes of global importance. Above all, Orlove reminds us that human relations with the environment, though constantly changing, can be sustainable.

"This book describes the physics of water flow into and out of lake systems, explaining the physical parameters that influence lake behavior and the mathematics that describes these systems. This book is aimed at working professionals, graduate and advanced undergraduate students of limnology, and researchers involved in lake management, lake remediation, or investigation of lake systems"--
“Lakes is my favorite kind of natural history: meticulously researched, timely, comprehensive, and written with imagination and verve.”—Jerry Dennis, author of The Living Great Lakes Lakes might be the most misunderstood bodies of water on earth. And while they may seem commonplace, without lakes our world would never be the same. In this revealing look at these lifegiving treasures, John Richard Saylor shows us just how deep our connection to still waters run. Lakes is an illuminating tour through the most fascinating lakes around the world. Whether it’s Lake Vostok, located more than two miles beneath the surface of Antarctica, whose water was last exposed to the atmosphere perhaps a million years ago; Lake Baikal in southern Siberia, the world’s deepest and oldest lake formed by a rift in the earth’s crust; or Lake Nyos, the so-called Killer Lake that exploded in 1986, resulting in hundreds of deaths, Saylor reveals to us the wonder that exists in lakes found throughout the world. Along the way we learn all the many forms that lakes take—how they come to be and how they feed and support ecosystems—and what happens when lakes vanish.
