  1. Northwest Forest Plan The First 15 Years (1994-2008): Watershed Condition Status and Trend

    We used two data sets to evaluate stream and watershed condition for sixth-field watersheds in each aquatic province within the Northwest Forest Plan (NWFP) area: stream data and upslope data. The stream...

  2. Engineering a Healthier Watershed: Middle School Students Use Engineering Design to Lessen the Impact of Their Campus'...

    It is important that students understand not only how their local watershed functions, but also how it is being impacted by impervious surfaces. Additionally, students need experience exploring the scientific...

  3. A Geospatial Tool for Wetland Prioritization at the Watershed Scale

    There is an increasing demand for assessing ecosystem functions for freshwater wetlands, especially when comparing or prioritizing among wetlands at the watershed scale. We estimated the relative potential of...

  4. Map-based Probabilistic Infinite Slope Analysis of the Stephens Creek Watershed, Portland, Oregon

    The Stephens Creek Watershed in southwest Portland, Oregon was chosen by the city as a pilot project for urban stream restoration efforts, and the infiltration of stormwater was identified as a potential...

  5. Riparian Vegetation Assemblages and Associated Landscape Factors Across an Urbanizing Metropolitan Area

    While diverse, native riparian vegetation provides important functions, it remains unclear to what extent these assemblages can persist in urban areas, and under what conditions. We characterized forested...

  6. Urban and Rural-residential Land Uses: Their Role in Watershed Health and the Rehabilitation of Oregon’s Wild Salmonids

    This technical report by the Independent Multidisciplinary Science Team (IMST) is a comprehensive review of how human activities in urban and rural-residential areas can alter aquatic ecosystems and resulting...

  7. Factors of Successful Collaboration: Oregon's Watershed Councils as Collaborative Systems

  8. Streamflow Modeling of Johnson Creek Subwatersheds Using the Precipitation Runoff Modeling System

    Johnson Creek, in the Portland, Oregon metropolitan region, has several pollutants on the U.S. Environmental Protection Agency’s (EPA) 303(d) list including excess heat, low dissolved oxygen, and harmful...

  9. Watershed Response to Climate Change and Fire-Burns in the Upper Umatilla River Basin, USA

    This study analyzed watershed response to climate change and forest fire impacts in the upper Umatilla River Basin (URB), Oregon, using the precipitation runoff modeling system. Ten global climate models using...

  10. Watershed Response to Climate Change and Fire-Burns in the Upper Umatilla River Basin Using the Precipitation Runoff Modeling...

    This study provides an analysis of watershed response to climate change and forest fire impacts, to better understand the hydrologic budget and inform water management decisions for present and future needs....
