(NWR-2012-9371) Dear Ms. Lee: Enclosed is the Endangered Species Act (ESA) Biological Opinion and Magnuson-Stevens Fishery Conservation and Management Act (MSA) Essential Fish Habitat (EFH) Consultation prepared by National Marine Fisheries Service (NMFS) regarding the U.S. Bureau of Reclamation's (Reclamation) Odessa Subarea Modified Partial Groundwater Replacement Project on the Colwnbia River in Adams, Lincoln, Franklin and Grant Counties, Washington. NMFS received a final biological assessment (BA) from Reclamation on November 6, 2012. Reclamation's BA determined that Columbia River chum salmon were likely to be adversely affected by the proposed action, 12 other species ofESA listed salmon and steelhead would not likely be adversely affected by the proposed action, and that Pacific eulachon, green sturgeon, and southern resident killer whales would not likely be adversely affected by the proposed action.

  • South Santiam Hatchery
    SOUTH SANTIAM HATCHERY PROGRAM MANAGEMENT PLAN 2020 South Santiam Hatchery/Foster Adult Collection Facility INTRODUCTION South Santiam Hatchery is located on the South Santiam River just downstream from Foster Dam, 5 miles east of downtown Sweet Home. The facility is at an elevation of 500 feet above sea level, at latitude 44.4158 and longitude -122.6725. The site area is 12.6 acres, owned by the US Army Corps of Engineers and is used for egg incubation and juvenile rearing. The hatchery currently receives water from Foster Reservoir. A total of 8,400 gpm is available for the rearing units. An additional 5,500 gpm is used in the large rearing pond. All rearing ponds receive single-pass water. ODFW has no water right for water from Foster Reservoir, although it does state in the Cooperative agreement between the USACE and ODFW that the USACE will provide adequate water to operate the facility. The Foster Dam Adult Collection Facility was completed in July of 2014 which eliminated the need to transport adults to and hold brood stock at South Santiam Hatchery. ODFW took over operations of the facility in April of 2014. The new facility consists of an office/maintenance building, pre-sort pool, fish sorting area, 5 long term post-sort pools, 4 short term post-sort pools, and a water-to-water fish-to-truck loading system. Adult fish collection, adult handling, out planting, recycling, spawning, carcass processing, and brood stock holding will take place at Foster The Foster Dam Adult Collection Facility is located about 2 miles east of Sweet Home, Oregon at the base of Foster Dam along the south shore of the South Santiam River at RM 37.

  • 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.

  • Lower Willamette River Environmental Dredging and Ecosystem Restoration Project
    LOWER WILLAMETTE RIVER ENVIRONMENTAL DREDGING AND ECOSYSTEM RESTORATION PROJECT INTEGRATED FEASIBILITY STUDY AND ENVIRONMENTAL ASSESSMENT DRAFT FINAL REPORT March 2015 Prepared by: Tetra Tech, Inc. 1020 SW Taylor St. Suite 530 Portland, OR 97205 This page left blank intentionally EXECUTIVE SUMMARY This Integrated Feasibility Study and Environmental Assessment (FS-EA) evaluates ecosystem restoration actions in the Lower Willamette River, led by the U.S. Army Corps of Engineers (Corps) and the non-Federal sponsor, the City of Portland (City). The study area encompasses the Lower Willamette River Watershed and its tributaries, from its confluence with the Columbia River at River Mile (RM) 0 to Willamette Falls, located at RM 26. The goal of this study is to identify a cost effective ecosystem restoration plan that maximizes habitat benefits while minimizing impacts to environmental, cultural, and socioeconomic resources. This report contains a summary of the feasibility study from plan formulation through selection of a recommended plan, 35% designs and cost estimating, a description of the baseline conditions, and description of impacts that may result from implementation of the recommended plan. This integrated report complies with NEPA requirements. Sections 1500.1(c) and 1508.9(a) (1) of the National Environmental Policy Act of 1969 (as amended) require federal agencies to “provide sufficient evidence and analysis for determining whether to prepare an environmental impact statement or a finding of no significant impact” on actions authorized, funded, or carried out by the federal government to insure such actions adequately address “environmental consequences, and take actions that protect, restore, and enhance the environment." The Willamette River watershed was once an extensive and interconnected system of active channels, open slack waters, emergent wetlands, riparian forests, and adjacent upland forests.

  • Natural Areas Restoration Plan October 2010
    Natural Areas Restoration Plan October 2010 Update: March 2015 Natural Areas Restoration Plan Update March 18, 2015 Portland Parks & Recreation (PP&R) completed the first system wide Natural Areas Restoration Plan (plan) in October 2010. The plan was completed as a requirement for Salmon Safe certification. It established restoration goals and strategies, management priorities and implementation actions. It is currently used to set restoration priorities (staff effort and funding) for natural areas. The plan stated that there would be a review and update every 3-5 years. The 2014 update modified the functional methodology and revised the weighting to remove the emphasis on salmonids and their habitat needs. The 2014 Natural Area Management Priority Matrix changes are based on the updated natural resource function methodology and ecological health determined by the best professional judgment of the ecologist managing the site. The goals, strategies and implementation actions remain the same. This updates also includes the natural area properties purchased since 2010. Methodology Update The methodology update evaluated additional functions and created a new weighting system. The original plan weighted functions associated with salmon habitat the highest while this update does not. Some of the updated functions were assigned weighted scores on a scale of 3 (high) to 1 (low) similar to the scoring used in the 2010 plan. A natural area was also given points for Terrestrial Ecology Enhancement Strategy (TEES) special status habitats and City of Portland At-Risk Species. The functions included are: (see attached memo for details): Streams: Perennial, non-perennial and within 100 feet of the natural area.

  • Willamette Valley Projects Configuration/Operation Plan (COP)
    Phase II Report Willamette Valley Projects Configuration/Operation Plan (COP) October 2015 Final Report Willamette Valley Projects Configuration/Operation Plan, Phase II Report EXECUTIVE SUMMARY The Configuration/Operation Plan (COP), Phase II Report, for the Willamette Valley system provides recommendations to address the Reasonable and Prudent Alternative (RPA) contained in the National Oceanic and Atmospheric Administration’s National Marine Fisheries Service (NOAA Fisheries or NMFS) 2008 Biological Opinion (BiOp) for the Willamette System (WS) operated and maintained by the US Army Corps of Engineers (USACE or Corps). The RPA listed actions to be implemented to avoid jeopardy to Upper Willamette River (UWR) spring Chinook salmon (Oncorhynchus tshawytscha) and UWR winter steelhead (O. mykiss) from continued operations and maintenance of the WS. This COP Phase II report was guided by the development of alternatives documented in the 2009 COP Phase I Report. Although this document does not meet the EC 11-2-208 (dated 31 Mar 2015) definition as a “Decision Document”, it is being used to document the long-term plan for implementing the 2008 Willamette Biological Opinion. BACKGROUND The WS system consists of 13 multipurpose dams and reservoirs, and approximately 92 miles of riverbank protection projects in the Willamette River Basin in Oregon. Each project contributes to the overall water resources management in the basin which is designed to provide flood risk management, hydropower generation, irrigation, navigation, recreation, fish and wildlife, and improved water quality on the Willamette River and many of its tributaries. The fish species listed under the Endangered Species Act (ESA) affected by operation of the WS1 include UWR spring Chinook salmon, UWR winter steelhead, and bull trout (Salvelinus confluentus, threatened).
