Wherever possible, 1:24,000 uniform scale geographic information system (GIS) data that covered the entire study area were used in this assessment. Goals of this study include, (1) a summary of current conditions for each 6th field watershed; and (2) recommendations for monitoring and management actions for prioritized 6th field watersheds.

  Citation × Citation Citation Abstract Copy Title: Limiting factors assessment and restoration plan Rock Creek : tributary to Devil's Lake, Lincoln County, Oregon Author: Bio-Surveys, LLC, Sialis Company This document provides watershed restoration actions proposed to enhance the Coho Salmon population within the Rock Creek / Devils Lake basin in Lincoln County, Oregon. The stream is the principle tributary of Devil’s Lake, a lake of natural origin that opens into the Pacific Ocean at the northern edge of Lincoln City, OR. The goal of the restoration effort has been to identify the dominant processes and habitat characteristics that currently limit the production of Coho salmon smolts in the basin, and to develop a prioritized list of actions (“prescriptions”) for removing the limitations in ways that normalize landscape and stream channel function. Restoration and assessment protocols used in developing the plan are described in “Midcoast Limiting Factors Analysis, A Method for Assessing 6th field subbasins for Restoration”, available at www.midcoastwatershedcouncil.org/GIS or by contacting the Midcoast Watersheds Council. Please refer to this document for detailed information on assessment, nomenclature, prioritization rationale and methodology.

  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.

  Citation × Citation Citation Abstract Copy Title: Rainfall-Runoff Prediction and the Effects of Logging : The Oregon Coast Range Author: Van Haveren, Bruce P., Jackson, William L. (William Longstreth) Streamflow response to rainfall is controlled by the net water budget and the routing of rainfall to stream channels. In rain-dominated forested regions, including the Oregon Coast Range, water budget aspects of forest hydrology are better quantified than water routing. As a result, most of the commonly used forest hydrology models have been designed to assist in the analysis of seasonal or annual runoff volumes (Goldstein, et al. 1974; Troendle and Leaf, 1980; Silvey and Rosgen, 1981). The effects of timber harvesting on runoff volumes are reflected primarily through reductions in evapotranspirational demand and the corresponding increases in soil water content. The purposes of the report are to: (1) Describe the rainfall-runoff processes in the Oregon Coast Range, and review the results of studies in Western Oregon on the effects of timber harvesting on runoff. (2) Review and analyze available techniques for predicting the hydrologic effects of timber harvesting in rainfall-dominated regions. (3) Provide a review of the issue of sediment routing, channel stability, and the relationship between hydrology and channel morphology. (4) Provide additional analysis of the Alsea Watershed Study data (Harris, 1977) to better describe the effects of timber harvesting on high-flow durations and assess the potential for developing and validating simple storm-period rainfall-runoff prediction procedures.
