This report presents an ecological assessment of non-tidal streams and rivers across twelve states of the western U.S., based on the results of a unique and experimental monitoring program implemented through the U.S. EPA's Environmental Monitoring and Assessment Program (EMAP) during the years 2000-2004. The two major objectives were to document the overall condition of the vast network of streams and rivers of the western U.S. and to demonstrate the utility and flexibility of an EMAP-like approach to environmental monitoring and assessment at this regional scale. The assessment is divided into two major categories. The first is the measurement of the ecological condition of streams and rivers in the West by direct measurements of their resident biological assemblages: aquatic vertebrates and benthic macroinvertebrates. The second is an assessment of the relative importance of potential stressors on those assemblages, based on direct measures of their chemical, biological and physical habitat.

Water Quality – Science, Assessments and Policy examines many of the scientific issues; national, regional and local assessment practices and results; and national policy issues related to water quality. Chapters focus on three areas: water quality parameters, water quality treatments, and water quality assessments. This book provides a basic understanding of water quality issues and practical examples of their solution.

The Environmental Monitoring and Assessment Program (EMAP) was developed by EPA to assess the condition of the nation's ecological resources. EMAP employs a statistical design that makes it possible to describe the proportion of the resource in good, fair or poor condition relative to reference condition. In 2000, the EMAP began a five-year effort to monitor and assess the ecological condition of rivers and streams across the West. This report uses a subset of the data from this large project and data from other EMAP projects to assess the ecological condition of the wadeable streams of the Interior Columbia River basin. Approximately 75,000 km of the 109,000 km of wadeable streams of the Basin were assessed for most indicators. In general, most streams of the basin are in fair or good condition based on the results of the metrics that could be analyzed. Primary stressors in terms of both extent and risk to biota are excess fine sediment, riparian disturbance from grazing/crops, sulfate, and phosphorous levels. -- Abstract, p. 1.

Intermittent Rivers and Ephemeral Streams: Ecology and Management takes an internationally broad approach, seeking to compare and contrast findings across multiple continents, climates, flow regimes, and land uses to provide a complete and integrated perspective on the ecology of these ecosystems. Coupled with this, users will find a discussion of management approaches applicable in different regions that are illustrated with relevant case studies. In a readable and technically accurate style, the book utilizes logically framed chapters authored by experts in the field, allowing managers and policymakers to readily grasp ecological concepts and their application to specific situations. Provides up-to-date reviews of research findings and management strategies using international examples Explores themes and parallels across diverse sub-disciplines in ecology and water resource management utilizing a multidisciplinary and integrative approach Reveals the relevance of this scientific understanding to managers and policymakers
