Conservation and Recovery Plan for Oregon Populations of Salmon and Steelhead FINAL – August 6, 2010 Appendix B Strata and Population Issues in Lower Columbia River Domain Planning This paper identifies several issues with strata and population definitions identified during the Oregon and Washington recovery plan domain roll-up process. These issues warrant further consideration and discussion at a technical level. This document is intended to be an informal working paper to facilitate further discussion and progress in moving forward with timely completion of a sound and defensible domain plan. Efforts to develop comprehensive recovery objectives as part of the Oregon and Washington domain planning effort led to a fresh examination of the biological basis for definitions of geographical/ecological sub-regions (strata) and demographically independent populations. These delineations are critical to definition of recovery objectives, priorities, and strategies consistent with TRT recovery criteria which require at least two populations per strata restored to high levels of viability and a strata average for all populations of medium plus (score of 2.25). The review considered: 1) Treatment of similar questions in recovery plans for Southern Oregon/Northern California Coast (SONCC) coho, Oregon Coastal coho, Puget Sound Chinook and chum, and Upper Columbia River salmon. 2) Documentation and support for the original delineations as reported by Myers et al. (2006) (Historical population structure of Pacific Salmonids in the Willamette River and Lower Columbia River Basins, NOAA Technical Memorandum NMFS-NWFSC-73), 3) New information and analysis of accessible habit areas by populations and minimum requirements to support demographically independent populations, 4) Modeling of recovery strategies conducted for Oregon and Washington to estimate viable population levels and gaps between current and target status. Issues with current delineations identified based on this review include: A. Delineations among Lower Columbia River strata (particularly Cascade and Gorge strata) appear to be subjective and inconsistent with ecoregion definitions identified as the basis of delineation. B. Several populations are identified in the gorge strata in areas where the historically accessible habitat does not appear adequate to support demographically independent populations. C. Strata and population designations result in gorge strata and delineations of questionable historical viability. Several populations appear to have been too small or fragmented to have been demographically independent. A combination of too few populations of too low inherent capacity suggests that high levels of viability cannot be reached without very great and unlikely improvements. The concern is whether implied recovery strategies are an artifact of subjective or erroneous assumptions. Page 5 – Appendix B Lower Columbia River Conservation and Recovery Plan for Oregon Populations of Salmon and Steelhead FINAL – August 6, 2010 Domain Treatments Strata and population identification was compared among recovery domains to examine the consistency in treatment of this problem in other areas. All domains except the relatively small upper Columbia, include some type of spatial and life history stratification scheme based on a mixture of geographical and ecological considerations. Lower Columbia: A total of 98 populations of Chinook, steelhead, coho, and chum were classified by three geographical zones and one (chum, coho), two (steelhead), or three (Chinook) life history types for a total of 17 groupings. Recovery objectives target at least two populations per strata restored to high levels of viability with a strata-wide average viability of better than “moderate.” Puget Sound Chinook: This ESU was separated into five bio-geographical regions consisting of 2 to 10 populations (total of 22). Recovery objectives target all existing independent populations for improvement, at least two to four populations per region to a low risk status, representing at least one viable population from each major genetic and life history group per region. Geographic regions were based on similarities in hydrographic, biogeographic,

    OREGON GUIDELINES FOR TIMING OF IN-WATER WORK TO PROTECT FISH AND WILDLIFE RESOURCES June, 2008 Purpose of Guidelines - The Oregon Department of Fish and Wildlife, (ODFW), “The guidelines are to assist under its authority to manage Oregon’s fish and wildlife resources has updated the following guidelines for timing of in-water work. The guidelines are to assist the the public in minimizing public in minimizing potential impacts to important fish, wildlife and habitat potential impacts...”. resources. Developing the Guidelines - The guidelines are based on ODFW district fish “The guidelines are based biologists’ recommendations. Primary considerations were given to important fish species including anadromous and other game fish and threatened, endangered, or on ODFW district fish sensitive species (coded list of species included in the guidelines). Time periods were biologists’ established to avoid the vulnerable life stages of these fish including migration, recommendations”. spawning and rearing. The preferred work period applies to the listed streams, unlisted upstream tributaries, and associated reservoirs and lakes. Using the Guidelines - These guidelines provide the public a way of planning in-water “These guidelines provide work during periods of time that would have the least impact on important fish, wildlife, and habitat resources.

  • Portland Harbor RI/FS Draft Final Remedial Investigation Report April 27, 2015
    Portland Harbor RI/FS Draft Final Remedial Investigation Report April 27, 2015 3.0 ENVIRONMENTAL SETTING This section describes the current and historical physical characteristics and human uses of the Portland Harbor Superfund Site. Physical characteristics of the site include meteorology, regional geology and hydrogeology, surface water hydrology, the physical system (which includes bathymetry, sediment characteristics, and hydrodynamics and sediment transport), habitat, and surface features. Human characteristics of the site that are discussed here include historical and current land and river use, the municipal sewer system, and human access and use. In addition to providing context to the RI sampling and analysis, the factors presented in this section are considered in the refinement of the Study Area-wide CSM, which is presented in Section 10. Sections 3.1 through 3.7 focuses primarily on the physical setting within the Study Area (RM 1.9 to 11.8). However, the physical features of the Willamette River from Willamette Falls (RM 26) to the Columbia River (RM 0), as well as the upstream portion of Multnomah Channel, are discussed as needed to place the Study Area’s physical characteristics into a regional context. The Willamette River basin has a drainage area of 11,500 square miles and is bordered by foothills and mountains of the Cascade and Coast ranges up to 10,000 feet high to the south, east, and west (Trimble 1963). The main channel of the Willamette forms in the southern portion of the valley near Eugene, at the convergence of the Middle and Coast forks. It flows through the broad and fertile Willamette Valley region and at Oregon City flows over the Willamette Falls and passes through Portland before joining the Columbia River (Map 3.1-1).

    City of Portland, Oregon Total Maximum Daily Load (TMDL) Implementation Plan Fourth Annual Status Report Fiscal Year 2011-2012 (July 1, 2011 – June 30, 2012) Submitted to: Oregon Department of Environmental Quality November 1, 2012 TMDL Implementation Plan Fourth Annual Status Report November 1, 2012 Introduction This Total Maximum Daily Load (TMDL) Implementation Plan Fourth Annual Status Report summarizes key activities and accomplishments for the City of Portland (City) during fiscal year (FY) 2011-2012 (July 1, 2011 to June 30, 2012). This is the fourth annual status report submitted by the City following the approval of the Total Maximum Daily Load (TMDL) Implementation Plan (IP) on March 6, 2009, in accordance with the Willamette Basin TMDL Water Quality Management Plan (WQMP). The IP was updated in FY11-12 to reflect the revised National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) Stormwater Management Plan (SWMP), and the updated portion was included in the third annual status report. This report does not encompass all elements of the TMDL Implementation Plan, but rather focuses on the most important implementation actions. It also does not quantify the pollutant load reduction of every activity because reliable, consistent, and universally accepted tools are currently not available to assess pollutant load reduction effectiveness of many of the actions (e.g., pollution prevention, education, stream restoration). For parameters with EPA-approved stormwater-related TMDL Waste Load Allocations (WLAs), pollutant load reductions from structural facilities within the City’s MS4 area are estimated as part of NPDES MS4 permit compliance. That evaluation was most recently conducted as part of the 2008 NPDES MS4 Permit Renewal Submittal (http://www.portlandonline.com/bes/index.cfm?c=50333&a=246071).

  • Appendix E: the City's Natural Environment
    APPENDIX E The City’s Natural Environment APPENDIX E The City’s Natural Environment The City’s Environmental Setting General Characteristics Portland is situated at 20 feet above sea level, near the confluence of the Columbia and Willamette rivers, about 65 miles inland from the Pacific Ocean. It lies midway between the lower Coast Range to the west and the high Cascades Range to the east, each about 30 miles distant. Portland’s varied topography includes steep hills, isolated volcanic cones, low rolling hills and extensive flat areas. The area is composed primarily of alluvial deposits and Columbia River basalts. Much of the city is located in the Willamette Valley Plains ecoregion, although steeper portions of the Tualatin Hills on the west side are characteristic of Willamette Valley Hills and Coastal Mountains ecoregions (Clarke and others 1991). Portland has a mild marine climate that is heavily influenced by the mountain ranges east and west of the city. The Coast Range protects the Portland area from Pacific storms, while the Cascades prevent colder continental air masses from invading western Oregon. In winter, the average temperature is 40°F and the average minimum temperature is 34°F. In summer the average temperature is 65°F with an average daily maximum of 74 to 78°F (Rockey 2002). The Cascades also lift moisture-laden westerly winds from the Pacific, driving local rainfall patterns. Average annual rainfall in the Portland area is approximately 37 inches. Nearly 90 percent of the annual rainfall occurs from October through May. Only 9 percent of the annual rainfall occurs between June and September, with 3 percent in July and August.

  • Sport Fishing Regulation Updates ‐ Last Updated July 23, 2013
    Sport Fishing Regulation Updates ‐ Last updated July 23, 2013 Oregon Sport Fishing Regulations provide requirements for all zones. However, additional regulations may be adopted in this rule division from time to time and to the extent of any inconsistency, they supersede the 2013 Oregon Sport Fishing Regulations. NORTHWEST ZONE Please note: Most recent updates are shown in bold red text. Beginning Jan. 1, 2013 the following tributaries of the Columbia will be restricted to barbless hooks when fishing for salmon, steelhead and trout: Youngs River from confluence with Youngs Bay upstream to markers at confluence with Klaskanine River. Lewis and Clark River from Hwy 101 bridge upstream to Alternate Hwy 101 bridge. Walluski River from confluence with Youngs Bay upstream to Hwy 202 bridge. Gnat Creek from railroad bridge upstream to Aldrich Point Road. Knappa/Blind Slough select areas. Three Rivers Open for adipose fin‐clipped spring chinook, adipose fin‐clipped summer steelhead and cutthroat trout through July 15. All regulations listed in the 2013 Oregon Sport Fishing Regulations will remain in place through the end the season. This includes the recent anti‐snagging gear restrictions that prohibit leaders longer than 36 inches, and limit anglers to a single point hook with a gap 3/8‐ inch or less. Trask River The ‘hatchery hole’ – the section of the Trask River located 200 feet above and 900 feet below its confluence with Gold Creek – will remain open to fishing through July 15. Bag limits, guidelines and closed areas remain the same and are described in the 2013 Oregon Sport Fishing Regulations.
