Bureau of Land Management. Marys Peak Resource Area, Delaini, Jack, Bacho, John P., U.S. Fish and Wildlife Service, Tai, Doris The Lower Alsea River Watershed Analysis contains information which characterizes the processes and trends for resources of concern, and provides a context relating the function of this lower portion of the watershed to the Alsea River Basin as a whole. Critical problem areas both inside and outside federal lands are highlighted, though the focus is on the uplands, with limited projection on the estuary, lowlands, private lands, and state facilities. By analyzing limiting factors and understanding likely rates of recovery, the analysis helps to strategize and prioritize activities both spatially and by project type. This first iteration provides useful information about resource conditions for USFS, BLM, and other agency managers as well as watershed councils and private individuals.

  Citation × Citation Citation Abstract Copy Title: Methods for multi-spatial scale characterization riparian corridors Author: Moser, Thomas J., Lindeman, Dale R., Schuft, Michael, Van Sickle, John, Wigington, P.J. This paper describes the application of aerial photography and GIS technology to develop flexible and transferable methods for multi-spatial scale characterization and analysis of riparian corridors. Relationships between structural attributes of riparian corridors and indicators of stream ecological conditions are not well established. As part of a research project focused on assessing riparian-stream systems in agricultural landscapes of Oregon's Willamette Valley, GIS land cover/land use databases were created from 1997 aerial photography and digital orthophotography for 23 predominantly agricultural watersheds, including detailed land cover-land use coverages within 150 m of perennial and intermittent streams. GIS functions were used to partition the stream networks at various lateral-longitudinal scales to quantify land cover/land use and to generate functionally relevant metrics of riparian vegetation, such as its composition, width, and continuity. The methods developed provide considerable flexibility for generating metrics characterizing attributes of riparian corridors and for exploring relationships among these metrics and indicators of stream ecological condition.

  Citation × Citation Citation Abstract Copy Title: Watershed restoration, jobs-in-the-woods, and community assistance : Redwood National Park and the Northwest Forest Plan Author: DeForest, Christopher E., Pacific Northwest Research Station (Portland, Or.) There are many parallels between the 1978 legislation to expand Redwood National Park and the Northwest Forest Plan, which together with the Northwest Economic Adjustment Initiative formed the 1993 Pacific Northwest Initiative. In both situations, the Federal Government sought to promote retraining for displaced workers, to undertake watershed assessment and restoration work, and to assist communities with economic planning, grants, and transitions. Both of these efforts point out the inherent conflicts between the economic and ecological objectives of watershed restoration. No one wants to have to choose between reducing sediment an reducing unemployment in coastal forests.

  Citation × Citation Citation Abstract Copy Title: McKenzie River focus watershed coordination : year end report 2000 Author: Thrailkil, Jim This report summarizes accomplishments of the McKenzie River Focus Watershed Council (MWC) in the areas of coordination and administration during Fiscal Year 2000. Coordination and administration consist of prioritization and planning for projects; project management and implementation; procurement of funding for long-term support of the Council; and watershed education/outreach program for residents and local schools. Key accomplishments in the area of project planning include coordinating: monthly Council and executive committee meetings; staffing the Upper Willamette Spring Chinook Working Group; staffing the water quality technical committee; and guiding education and stewardship projects. Key accomplishments in the area of project management include the completion of the McKenzie-Willamette Confluence Assessment; securing funds for project planning in the confluence area; near completion of the BPA funded McKenzie sub-basin assessment; development of a framework for a McKenzie Watershed Conservation Strategy; an evaluation of Council’s monitoring programs - ambient water quality, storm-event water quality, Tier III water quality, and macroinvertebrate monitoring. The Council, in cooperation with the McKenzie River Cooperative, completed habitat enhancements in the Gate Creek and Deer Creek sub-watersheds. This partnership recently submitted Bring Back the Natives grant for initiation of projects in other McKenzie tributaries. The Council will also be working with a local business to develop a river-side riparian enhancement and native landscaping project on the lodge grounds. This will serve as a demonstration project for blending fish and wildlife habitat concerns with maintaining grounds for business opportunities. Accomplishments in the area of procurement of funding included developing the FY2000 Scope of Work and budget for approval by the Council and BPA; providing quarterly budget and work program progress reports to the Council; and securing additional funding from Council partner organizations and foundations. Highlights in the area of watershed education/outreach include the MWC’s lead role in convening the Watershed Education Network for teachers as part of its educational mission; production of newsletters and brochures; and coordination of media coverage of watershed-related issues. MWC completed all tasks outlined in the FY2000 Scope of Work with the following staff: Watershed Coordinator (1.0 FTE), Project Coordinator (.25 FTE), and Education Coordinator (0.5 FTE). Coordination of these activities by MWC improves resource stewardship and protects fish and wildlife habitat through increased collaboration among Federal, state, and local government agencies, and landowners within the watershed. Increasing awareness and expanding knowledge affects behavior positively and promotes attitudes that encourage watershed stewardship. During Fiscal Year 2001, MWC intends to focus on an Implementation Strategy based on the McKenzie sub-basin assessment results; implementation of projects recommended from the McKenzie-Willamette confluence assessment; and increasing its presence at the local level through contact with watershed residents and groups.

The purposes of this report are to describe the quality of shallow ground water in alluvial aquifers of the Willamette Basin and to identify relationships between shallow ground-water quality and various natural and anthropogenic factors. Several natural and anthropogenic factors (soil characteristics, cumulative thickness of clay above open interval of well, surficial geology, and land use) were evaluated because of the potential for these factors to either control or be related to contaminant occurrence and spatial distribution. Spatial distributions of nitrite plus nitrite, phosphorous, pesticides and pesticide degradation products, volatile organic compounds (VOCs), trace elements (primarily arsenic, a trace element of local concern), and radon were evaluated for 1993-95. Ancillary chemical data--nitrite, chloride, tritium (H-3), and dissolved-oxygen (DO) concentrations--also are presented.
