Wetlands Drainage, River Modification, and Sectoral Conflict in the Lower Illinois Valley, 1890-1930 John Thompson   December 2001 352 pages, 42 illus., 6 x 9 ISBN 0-8093-2398-2, $60..00s cloth Environmental Studies With support form the U.S. Geological Survey Upper Midwest Environmental Sciences Center   “Wetlands Drainage, River Modification, and Sectoral Conflict in the Lower Illinois Valley, 1890-1930 is the only detailed account of the demise of natural wetlands along the Illinois River and the development of levee systems and their effect on wetlands. It is one of the most superior scholarly works I have reviewed. It brings together, in orderly form, a massive amount of information that has never before been assimilated.” —Robert Mohlenbrock   John Thompson provides a historical account of the development process, sectoral conflicts, and outcomes related to major alterations of land and water relationships, as well as habit changes, caused in the valley downstream from Peoria by the large-scale reclamations for agriculture and the post-1900 intrusion of large volumes of waste water from the Sanitary and Ship Canal of Chicago.              Thompson examines the history of the land drainage movement and the inevitable environmental changes caused by the intensification of urban and rural land use in the Midwest between sixty and one hundred years ago. He shows how institutions of land drainage were organized and operated and how the nascent drainage engineering and contracting sectors functioned. Focusing on the lower valley, Thompson also deals with drainage as it affects the nation, the Midwest, Chicago, and downstate Illinois.   Thompson is the first to address the array of interrelated physical, economic, and political circumstances caused by the development of competing and incompatible uses for the waters and the floodplain of the Illinois River when large-scale land reclamation and great volumes of water from Lake Michigan and Chicago changed land and water relationships, destroyed a major riverine fishing industry, and severely damaged renowned waterfowl hunting grounds.             John Thompson is a professor emeritus of geography at the University of Illinois, Urbana-Champaign. He is the coauthor of The Tule Breakers: The Story of the California Dredge (with E. A. Dutra) and the author of Flood Chronologies and Aftermaths Affecting the Lower Sacramento River, 1878-1909.
