  1. Restoration in the Lower Columbia River and Estuary September 13, 2007 Debrah Marriott, Executive Director Evan Haas, Habitat Restoration Coordinator

  2. Lower Columbia Challenges • Bi-State Investment 1989 - 1995 • Combined monitoring efforts at over 500 sites – • looking at fish tissue, sediment and water quality • Habitat decreased by as much as 75% from historical levels • Beneficial uses impaired • High levels of sediment contamination • DDEs, PCBs, dioxins and furans, and PAHs • Contaminants are bioaccumulating at harmful levels • Bald eagle, osprey, and river otters • High water temperature and dissolved gas levels

  3. Lower River & EstuaryManagement Plan Objectives • Protect the ecosystem and species -restoring 16,000 acres of wetlands and habitat by 2010 • Reduce toxic and conventional pollution -conducting long term monitoring. • Provide information about the river to a range of audiences -compiling and evaluating data, offering education programs for children and building public and private partners.

  4. Science Program Components Habitat Restoration • Regional Prioritization Strategy • Shoreline Videography: Assessment of Conditions/ Landscape Analysis • Inventory • Project Implementation & Effectiveness Monitoring • Sediment Management Species Recovery Monitoring and Toxic Reduction

  5. Historic Habitat Loss

  6. Restoration Tools & Data: Defining Regional Strategies and Priorities • Emerging Information • Monitoring for toxic contaminants • Fish Surveys • Ecosystem Classification: Lidar • Prioritization Strategy • Classifies lower river based on landscape characteristics • Defines needed restoration activities • Improves cost effectiveness • Project Review Criteria • 100 Scientists, Directs project selection • Shoreline Inventory • 630 miles videographed and classified shoreline features • Identifies high priority restoration sites

  7. Regional Restoration Inventory

  8. Active Partners • Council / BPA: $4,000,000 2003-2007; estimated $4,500,000 2008-2010 • Council / BPA: Pile Dike Removal (proposed) • NOAA – Community Based Restoration Partnership: $666,250 2004-2007, est. $750,000 2008-2010 • NOAA – Marine Debris: $100,000 2008 • EPA – Targeted Watershed $700,000 2003-2005 • Corps of Engineers - Section 536: $2M since 2002 Implementers Estuary Partnership, Local Governments, Conservation Organizations, Watershed Councils, CREST, WA Fish Recovery Board

  10. Brownsmead/Blind SloughTidal Reconnection CREST and project partners reconnected 7 miles of slough to tidal influence Remove culvert barriers Install fish friendly tidegates Post Monitoring shows water temperatures are declining.

  11. Restoration Projects - 2008 Restoration • Otter Point: dike breach • Stephens Creek: CSO pipe removal/wetland grading • Mirror Lake: culvert replacement • Scappoose Bottomlands: wetland revegetation • Crazy Johnson Creek: land acquisition Marine Debris • Coal Creek Slough: remove abandoned pile dikes. Pile Dike Removal • Proposed for 2008: build off work at Coal Creek Slough and increase removal throughout the estuary

  12. Sediment Management Sediment Plan will: • Provide regional decision making context • Assess Contamination Issues • Identify disposal issues: location, costs • Impacts to habitat • Creation of predator habitat • Loss of instream habitat

  13. Species RecoveryNWPCC, BPA & NOAA Confirm recovery priorities in Management Plan: • Sub Basin Plan for lower river and estuary, 2004 – six priority areas: hydro system effects, habitat, toxic contaminants, non-native species, predation, and uncertainty • Phase 2 Recovery module for lower river and estuary 2007 Threats: flow, sediment impairment, structures, food web and predators, riparian practices and toxic contaminants. • Action Agencies- Comprehensive Analysis – August 2007

  14. Estuary Partnership Monitoring Strategy Developed 1996-1999 with USGS and large work group of public and private sector scientists Assessed current activities, needs and gaps Defined plan to fill gaps The plan includes the following components: Monitoring Oversight Data Management Habitat Monitoring Exotic Species Conventional Pollutants Toxic Contaminants Primary Productivity and Food Web Dynamics

  15. Monitoring to Date • 1989 – 1996: Bi-State $6,000,000: Gives us Baseline at over 500 sites • 1996- 2005: One time Snapshots gives us quick look • EPA EMAP: $500,000 & USGS BEST: $3,000,000 • 2003-2007: Council & BPA investment $2,300,000 gave us: • Ecosystem Classification System • Habitat Monitoring (exotic species) • Water Quality Monitoring – USGS matched BPA funds • Salmonid Sampling –NOAA matched BPA funds • Toxics Model Development • 2008-2010: Council & BPA investment $1,875,000 will give us: • Trend Ability • Ecosystem Classification System • Habitat monitoring (exotic species) • Salmonid Sampling (No toxics) – NOAA matching

  16. Results of Monitoring Project Legacy, Bioaccumulative, Persistent • Contaminants banned from 1970s still detected in sediments and fish, including pesticides, (DDT), coolants and lubricants (PCBs) • PCBs in salmon tissue and PAHs present in salmon prey exceed estimated thresholds for delayed mortality, increased disease susceptibility, and reduced growth Emerging, sublethal • Flame retardants (PBDEs) on the rise and salmon in the vicinity of Portland have levels within the top 10% of those reported for resident fish in the region • Copper detected at concentrations known to interfere with salmon olfaction: imprinting, homing, schooling, shoaling, predator detection, predator avoidance, and spawning • Juvenile Chinook salmon collected from the Portland area have abnormal levels of an estrogen-regulated yolk protein

  17. Future Activities: Based On What We Know, What Do We Need? • More strategic approach • More aggressive identification of projects • Continue tidal reconnection projects and increase marine debris and pile dike removal projects • Link effectiveness monitoring to results • Expand knowledge of fish use in tidal freshwater portion of the estuary • Expand involvement from local, state, federal and tribal partners
