  • Wallowa County Community Sensitivity and Resilience
    Wallowa County Community Sensitivity and Resilience This section documents the community’s sensitivity factors, or those community assets and characteristics that may be impacted by natural hazards, (e.g., special populations, economic factors, and historic and cultural resources). It also identifies the community’s resilience factors, or the community’s ability to manage risk and adapt to hazard event impacts (e.g., governmental structure, agency missions and directives, and plans, policies, and programs). The information in this section represents a snapshot in time of the current sensitivity and resilience factors in the community when the plan was developed. The information documented below, along with the findings of the risk assessment, should be used as the local level rationale for the risk reduction actions identified in Section 4 – Mission, Goals, and Action Items. The identification of actions that reduce a community’s sensitivity and increase its resilience assist in reducing the community’s overall risk, or the area of overlap in Figure G.1 below. Figure G.1 Understanding Risk Source: Oregon Natural Hazards Workgroup, 2006. Deleted: _________ County Deleted: Month Year Deleted: 2 Northeast Oregon Natural Hazard Mitigation Plan Page G-1 Community Sensitivity Factors The following table documents the key community sensitivity factors in Wallowa County. Population • Wallowa County has negative population growth (-1.3% change from 2000-2005) and an increasing number of persons aged 65 and above. In 2005, 20% of the population was 65 years or older; in 2025, 25% of the population is expected to be 65 years or older. Elderly individuals require special consideration due to their sensitivities to heat and cold, their reliance upon transportation for medications, and their comparative difficulty in making home modifications that reduce risk to hazards.

  • The Geology of Part of the Snake River Canyon and Adjacent Areas in Northeastern Oregon and Western Idaho
    AN ABSTRACT OF THE THESIS OF Tracy Lowell Vallier for the Ph.D. in Geology (Name) (Degree) (Major) Date thesis is presented May 1, 1967 Title THE GEOLOGY OF PART OF THE SNAKE RIVER CANYON AND ADJACENT AREAS IN NORTHEAXERN OREGON AND WESTERN IDAHO Abstract approved Redacted for Privacy (Major professor) The mapped area lies between the Wallowa Mountains of northeastern Oregon and the Seven Devils Mountains of western Idaho. Part of the Snake River canyon is in- cluded. A composite stratigraphic section includes at least 30,000 feet of strata. Pre- Tertiary and Tertiary strata are separated by a profound unconformity. Pre -Tertiary layered rocks are mostly Permian and Triassic volcani- clastic and volcanic flow rocks. At least four pre -Ter- tiary intrusive suites occur. Tertiary rocks are Miocene and Pliocene plateau basalts. Quaternary glacial materi- als and stream deposits locally mantle the older rocks. Permian ( ?) rocks of the Windy Ridge Formation are the oldest rocks and consist of 2,000 to 3,000 feet of keratophyre, quartz keratophyre, and keratophric pyro- clastic rocks. Unconformably ( ?) overlying the Windy Ridge Formation are 8,000 to 10,000 feet of volcaniclastic rocks and minor volcanic flow rocks of the Hunsaker Creek Formation of Middle Permian (Leonardian and Wordian) age. Spilitic flow rocks of the Kleinschmidt Volcanics are interlayered with and in part overlie the Hunsaker Creek Formation and comprise a sequence about 2,000 to 3,000 feet thick. The Paleozoic layered rocks were intruded by the Holbrook - Irondyke intrusives, composed of keratophyre porphyry, quartz keratophyre porphyry, diabase, and gab- bro.

    MONITORING AND EVALUATION PROGRESS REPORT Lower Snake River Compensation Plan Nez Perce Tribe Hatchery Evaluation Studies Fiscal Year 2014 William P. Young Nez Perce Tribe Department of Fisheries Resources Management P.O. Box 365 Lapwai, ID 83540 December, 2014 2014 EVALUATION PROGRESS REPORT 1.Objectives A. General The NPT LSRCP Monitoring and Evaluations Project (LSRCP M&E) will coordinate LSRCP hatchery production planning and evaluations and provide information and recommendations for the Nez Perce Tribe Executive Committee (NPTEC). LSRCP M&E personnel will also attend coordination, marking and tagging and all other pertinent LSRCP meetings and activities with the states of Idaho, Oregon, and Washington and with the U.S. Fish and Wildlife Service. Work schedules will be coordinated with tribes, states and federal agencies to maximize cooperation in monitored streams in the Clearwater, Salmon, Grande Ronde, Imnaha and Tucannon Rivers within the Snake River basin in order to establish baseline data for determining the relative success and effects of releasing hatchery-reared fish in these streams. The Northwest Power Planning Council’s Artificial Production Review (NPPC 1999) recommends a comprehensive set of performance measures that should be monitored in all artificial propagation programs and will be used to guide independent reviews of artificial propagation programs. In addition to contributing to the co-management of the LSRCP program, the NPT LSRCP M&E project is structured to monitor and evaluate LSRCP hatchery production performance, natural production status and performance, genetic diversity. Monitoring activities will include adult escapement of both natural and hatchery origin Chinook salmon in several key spawning aggregates, pre-release sampling of LSRCP hatchery-produced fish, monitoring of life stage survival of naturally and hatchery produced fish, and identification of the genetic stock structure.
