Book Description
The need to address instream flow needs (IFN) in the Northern River Basins Study arises primarily from issues related to flow regulation on the Peace River. Flow regulation may have effects on fish habitats and has clearly affected riparian habitats in the study area. This report presents proceedings of a workshop held to review methods and approaches for conducting IFN analyses, to consider their applicability to the northern river basins, and to develop recommendations for undertaking IFN investigations as part of the Study. The workshop included two sessions, one on IFN related to fisheries and aquatic habitats and one on IFN related to riparian and delta habitats. Topics of presentations and papers include river hydrology, water quality considerations, vegetation studies, instream flow assessment, winter habitat, implications of river impoundment, modelling of wildlife habitat, channel morphology, sediment transport, and wetland vegetation management.

Book Description
Lists Northern River Basins Study technical reports by issue number, subject, and geographic area studied. Subject areas used to classify the reports are: hydrology/hydraulics, nutrients/dissolved oxygen, contaminants, food chain, drinking water, other uses, traditional knowledge, and synthesis and modelling. Ten geographic divisions are used: three each for the Athabasca and Peace Rivers, and one each of the Wapiti/Smoky rivers, Peace-Athabasca Delta, Lake Athabasca, and Rivière des Rochers/Slave River.

Book Description
The NTBS was designed to address the ecological concerns about pulp mill expansion, and to increase scientific knowledge about environmental conditions [ecology, ecosystem sustainability, water pollution and control, habitat, effect on fish and fishing, etc.] in the major river systems of the north. The study's objectives were to gather and interpret sound scientific information about the basins, develop appropriate recommendations for basin management, and communicate effectively with the public. The government response report confirms the governments' commitment to ecosystem sustainability and to pollution control in northern rivers. First Nations and Metis aboriginal [native] peoples contributed significantly to the NRBS.

Book Description
The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Book Description
The tension between wildlife protection under the Endangered Species Act and water management in the Platte River Basin has existed for more than 25 years. The Platte River provides important habitat for migratory and breeding birds, including three endangered or threatened species: the whooping crane, the northern Great Plains population of the piping plover, and the interior least tern. The leading factors attributed to the decline of the cranes are historical overhunting and widespread habitat destruction and, for the plovers and terns, human interference during nesting and the loss of riverine nesting sites in open sandy areas that have been replaced with woodlands, sand and gravel mines, housing, and roadways. Extensive damming has disrupted passage of the endangered pallid sturgeon and resulted in less suitable habitat conditions such as cooler stream flows, less turbid waters, and inconsistent flow regimes. Commercial harvesting, now illegal, also contributed to the decline of the sturgeon. Endangered and Threatened Species of the Platte River addresses the habitat requirements for these federally protected species. The book further examines the scientific aspects of the U.S. Fish and Wildlife Service's instream-flow recommendations and habitat suitability guidelines and assesses the science concerning the connections among the physical systems of the river as they relate to species' habitats.

Book Description
The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book Description
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
