Available in PDF, EPUB and Kindle. Book excerpt: For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use of other waste-management practices. As a result, summer dissolved-oxygen levels have increased, salmon runs have returned, and the overall effort is widely regarded as a singular water-quality success. To document the improved dissolved-oxygen regimen, the U.S. Geological Survey conducted intensive studies of the Willamette during the summer low-flow seasons of 1973 and 1974. During each summer the mean daily dissolved-oxygen levels were found to be higher than 5 milligrams per liter throughout the river. Because of the basinwide secondary treatment, carbonaceous deoxygenation rates were low. In addition, almost half of the biochemical oxygen demand entering the Willamette was from diffuse (nonpoint) sources rather than outfalls. These results indicated that point-source biochemical oxygen demand was no longer the primary cause of dissolved-oxygen depletion. Instead, the major causes of deoxygenation were nitrification in a shallow ' surface active ' reach below Salem and an anomalous oxygen demand (believed to be primarily of benthal origin) in Portland Harbor.

Book excerpt: "The Willamette River Basin Planning Atlas offers a valuable resource for anyone interested in the region's past, present, and future. Using a variety of color maps, charts, and photographs, the Atlas presents a vast amount of information intended to provide a long-term, large-scale view of changes in human and natural systems within the Basin." "Five chapters provide information on current conditions and historical changes since 1850, focusing in turn on land forms and geology, water resources, plants and animals, land use, and human population." "Next, there is a detailed examination of how the Basin may change between now and 2050 under three alternative scenarios for future land and water use: one assuming a continuation of current land use and management policies, the second assuming a loosening of current policies to allow freer development, and the third assuming greater emphasis on ecosystem protection and restoration." "The final chapter demonstrates how the information and analyses presented in the Atlas can be used to prioritize and design river restoration strategies. Although the focus is on the Willamette River and its floodplain, the book's approach provides a useful model that can be applied to other regions as well." "Intended for general readers and specialists alike, the Atlas provides information to help local citizens, policymakers, and scientists make better decisions about the Willamette River Basin and its future."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
