  Citation × Citation Citation Abstract Copy Title: Miami River watershed assessment : final report Author: E&S Environmental Chemistry, Inc., Sullivan, Timothy J., White, Shawn, Snyder, Kai U., Raymond, Richard B., Binder, Susan K., Bischoff, Joseph M. The purpose of this watershed assessment is to inventory and characterize watershed conditions of the Miami River watershed and to provide recommendations that address the issues of water quality, fisheries and fish habitat, and watershed hydrology. This assessment was conducted by reviewing and synthesizing existing data sets and some new data collected by the watershed council, following the guidelines outlined in the Oregon Watershed Enhancement Board (OWEB) watershed assessment manual (WPN 1999).

  Citation × Citation Citation Abstract Copy Title: Nehalem River watershed assessment Author: Maser, Jospeh, Johnson, Jill Watershed assessment is a process for evaluating how well a watershed is working. The purpose of this assessment was to determine how natural and human-induced changes have impacted the sustainability of salmon populations in the Nehalem River Watershed. Both historical and current information is included regarding the watershed’s ability to produce clean water and healthy salmon habitat. The assessment was prepared for the Upper and Lower Nehalem River Watershed Councils. It will be a baseline for developing and prioritizing potential restoration projects in terms of fish habitat. Geographic Information Systems (GIS) was used for much of the analysis and has been provided to the watershed councils.

  Citation × Citation Citation Abstract Copy Title: A systems classification of watersheds and streams Author: McCullough, Dale A. Adequate management and scientific investigation of ecosystems depends on classification of landscape systems based on all significant bio-physical and associated cultural properties. The present classification is a hierarchical systems design that can be modeled in terms of a natural system interacting with its level-specific environment. A watershed system in this context is embedded in a landscape environment organized into, for example, zonal and regional systems. A system at any level is classified by its capacity and the capacity of its environment, capacity defining temporally the scope of possible system performances relative to the components, substrate, climate, biota, culture, and water. This theoretical framework for examining systems was translated into methods suitable for integrating the full capacities of watersheds and for displaying the discrete and continuous nature of watershed and stream system similarities. Classification of land to a sub-zonal level with a full capacity description coupled with analysis of watershed substrate variables provided an adequate representation of watershed capacity. This was demonstrated by empirical correlations of system, components described in the literature, and by the ability to predict soil properties from topographic characteristics of land facets that are formed on a grid system overlaid on the watershed. Watershed classes were shown to be a good surrogate for differentiation of stream classes. Watersheds were analyzed by facet on a grid system according to several substrate variables. Slope, aspect, altitude, radiation intensity on the winter solstice and equinox, and soil series occurrence by facet effectively sorted watershed and stream classes. These same classes were also revealed by a more extensive set of variables describing the statistical distribution of these primary variables and some variables describing topographic roughness, form, and drainage development. Spatial organization of the basin is a significant factor determining solar radiation distribution on slope facets and in segments of the drainage network. A gravity model of spatial organization of soils is potentially a useful model for stream reach performances, considering the reach environment as the upstream segment, network, and watershed system.

  Citation × Citation Citation Abstract Copy Title: The Oregon plan for salmon and watersheds: a perspective. Author: Institute for Natural Resources, Salwasser, Hal, Achterman, Gail, Arha, Kaush The Oregon Plan is a state-led strategy for restoring and conserving native salmonids and the watersheds within which they spend all or parts of their lives. It evolved from work that began in the 1980s on watershed health and salmon conservation and was propelled into high gear by proposed and eventual listings of native salmonids in Oregon under the federal Endangered Species Act during the mid-1990s. The Plan has expanded in scope and activities since then, and now encompasses all native salmonids and all watersheds in the state. It has spawned new commitments and investments from private landowners and generated significant improvements in state agency coordination related to salmonids and watershed health. The accomplishments of the Oregon Plan create an unparalleled foundation for state-led species conservation. The work remaining creates abundant opportunity for new leaders to add their embellishments to the fine work of others to date. Title: The Oregon plan for salmon and watersheds: a perspective.
