Book Description
Throughout the history of the Great Lakes many organizations have played important roles in the growth and development of the water system. Charting the Inland Seas highlights the work done by the U.S. Lake Survey, one of the most notable, yet least known, organizations in the history of the Great Lakes. With the first great influx of settlers into the Great Lakes region came the need for extensive surveys and accurate navigational charts. In the 1830s shipowners and masters pressed the federal government to begin a thorough survey of the Great Lakes in order to make available detailed maps and charts of the various routes by which the lakes could safely be sailed. In 1841, Congress appropriated $15,000 for the Corps of Topographical Engineers to begin a survey of the northern and northwestern lakes, thus marking the formation of the United States Lake Survey. Arthur M. Woodford documents how the role and responsibility of the Lake Survey grew as conditions on the Great Lakes changed over the next 135 years. Great Lakes ships evolved into larger vessels with greater drafts, creating the need for new and more exact surveys and charts. In order to more accurately predict the water levels of the Great Lakes, special forecasting techniques evolved. When erosion of beaches threatened to destroy valuable lakefront property, extensive studies by the Lake Survey determined the causes. And as the number of recreational crafts increased, a program began for the design and publication of large scale book charts for boaters to use. In addition, the U.S. Lake Survey was one of the military's major suppliers of maps and charts during the two world wars and the Korean conflict. In 1970 the federal government established the National Oceanic and Atmospheric Administration (NOAA) as part of the Department of Commerce, and brought together, in a single agency, the major federal programs dealing with the seas and the atmosphere, and the U.S. Lake Survey was reorganized. In 1976, the U.S. Lake Survey was completely phased out, concluding an important chapter in the history of the Great Lakes.

Book Description
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.

Book Description
New York Times Bestseller Winner of the Los Angeles Times Book Prize Winner of the J. Anthony Lukas Award "Nimbly splices together history, science, reporting and personal experiences into a taut and cautiously hopeful narrative.… Egan’s book is bursting with life (and yes, death)." —Robert Moor, New York Times Book Review The Great Lakes—Erie, Huron, Michigan, Ontario, and Superior—hold 20 percent of the world’s supply of surface fresh water and provide sustenance, work, and recreation for tens of millions of Americans. But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan’s compulsively readable portrait of an ecological catastrophe happening right before our eyes, blending the epic story of the lakes with an examination of the perils they face and the ways we can restore and preserve them for generations to come.
