In 1988, the U.S. Army Corps of Engineers began an investigation of the benefits and costs of extending several locks on the lower portion of the Upper Mississippi River-Illinois Waterway (UMR-IWW) in order to relieve increasing waterway congestion, particularly for grain moving to New Orleans for export. With passage of the Flood Control Act of 1936, Congress required that the Corps conduct a benefit-cost analysis as part of its water resources project planning; Congress will fund water resources projects only if a project's benefits exceed its costs. As economic analysis generally, and benefit-cost analysis in particular, has become more sophisticated, and as environmental and social considerations and analysis have become more important, Corps planning studies have grown in size and complexity. The difficulty in commensurating market and nonmarket costs and benefits also presents the Corps with a significant challenge. The Corps' analysis of the UMR-IWW has extended over a decade, has cost roughly $50 million, and has involved consultations with other federal agencies, state conservation agencies, and local citizens. The analysis has included many consultants and has produced dozens of reports. In February 2000, the U.S. Department of Defense (DOD) requested that the National Academies review the Corps' final feasibility report. After discussions and negotiations with DOD, in April 2000 the National Academies launched this review and appointed an expert committee to carry it out.

In June 1854 the Grand Excursion celebrated in festive style the completion of the Chicago and Rock Island Railroad to the Mississippi River. Hundreds of dignitaries including newspaper editors and other journalists; politicians; academics, writers and artists; business and industry leaders; and railroad officials were among those who traveled by rail from Chicago to Rock Island, Illinois, then by steamboat to St. Paul in Minnesota Territory. The travelers were shown a region undergoing rapid settlement by Europeans—an area of great natural beauty offering many promises for additional development. One hundred and fifty years later, the thirteen essays in this volume examine the activities and environments of the 1854 Grand Excursion and place them in the context of an evolving regional identity for the Upper Mississippi River Valley based on the economy, culture, geography, and history of the area. In a series of “excursions,” the contributors explore the building of the Chicago and Rock Island Railroad, eastern newspaper accounts of the 1854 excursion, steamboating, the area’s pictorial landscape, passenger trains along the scenic river, the genesis and features of river towns, the control of the river for navigation, the development of preserves, parks, and recreation areas, the lumber industry, and commercial fishing. The book concludes by examining the resurgence of river-oriented development, as river towns are once again embracing the Mississippi. Generously illustrated with maps, engravings, ephemera, and historic and present-day photographs, Grand Excursions on the Upper Mississippi River will be of interest to tourists and residents of the area, river aficionados, railroad and steamboat history buffs, as well as academics interested in the history, geography, and regional development of the area.

This engaging and well-illustrated primer to the Upper Mississippi River presents the basic natural and human history of this magnificent waterway. Immortal River is written for the educated lay-person who would like to know more about the river's history and the forces that shape as well as threaten it today. It melds complex information from the fields of geology, ecology, geography, anthropology, and history into a readable, chronological story that spans some 500 million years of the earth's history. Like the Mississippi itself, Immortal River often leaves the main channel to explore the river's backwaters, floodplain, and drainage basin. The book's focus is the Upper Mississippi, from Minneapolis, Minnesota, to Cairo, Illinois. But it also includes information about the river's headwaters in northern Minnesota and about the Lower Mississippi from Cairo south to the river's mouth ninety miles below New Orleans. It offers an understanding of the basic geology underlying the river's landscapes, ecology, environmental problems, and grandeur.
