Available in PDF, EPUB and Kindle. Book excerpt: "In Wide Rivers Crossed, Ellen Wohl tells the stories of two rivers—the South Platte on the western plains and the Illinois on the eastern—to represent the environmental history and historical transformation of major rivers across the American prairie. Wohl begins with the rivers’ natural histories, including their geologic history, physical characteristics, ecological communities, and earliest human impacts, and follows a downstream and historical progression from the use of the rivers’ resources by European immigrants through increasing population density of the twentieth century to the present day. The environmental changes in the South Platte and the Illinois reflect the relentless efforts by humans to control the distribution of water: to enhance surface water in the arid western prairie and to limit the spread of floods and drain the wetlands along the rivers in the water-abundant east. In addition, during the past two centuries crops replaced native vegetation; excess snowmelt and rainfall carried fertilizers and pesticides into streams; and levees, dams, and drainage altered distribution. These changes cascaded through networks, starting in small headwater tributaries, and reduced the ability of rivers to supply the clean water, fertile soil, and natural habitats they had provided for centuries. Understanding how these rivers, and rivers in general, function and how these functions have been altered over time will allow us to find innovative approaches to restoring river ecosystems. Wide Rivers Crossed looks at these historical changes and discusses opportunities for much needed protection and restoration for the future."

Book excerpt: Excerpt from Identification of Toxic Substances in the Upper Illinois River: Final Report During the course of this study, several species of fingernail clams, includ ing M. Transversum, reappeared in the Chicago area waterways and in the Illinois River at Peoria and Havana. There are at least four possible explanations for this surprising reappearance of clams in the same general areas where the porewaters tested toxic. First, we found that clams recolonizing the upper Illinois are more resistant to ammonia than the clams from the lower Illinois, where the organisms were obtained for all of the early bioassays. Second, our previous research demon strated that the surface layers of sediment in some areas are less toxic than layers a few centimeters deeper. Toxicity may have been overestimated in tests where surface and deep layers of sediment were mixed prior to testing. Third, toxic episodes may be brief and infrequent, allowing organisms to colonize in between episodes. Fourth, the distribution of toxicity in sediments may be extremely patchy, so that healthy organisms are found adjacent to barren areas. If the latter two hypotheses prove to be true, acute toxicity in the Illinois River has changed recently from a widespread problem to a more localized or episodic problem. Reduction of toxicity in surface sediments may reflect recent reductions in ammonia loading from sewage treatment plants in the Chicago area, although it is not clear whether the sources of ammonia in the porewaters are effluents, the deeper layers of sediments, or both.
