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

Lower Columbia Challenges Bi-State Investment 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

Lower River & Estuary Management Plan 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. Objectives

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

Historic Habitat Loss

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

Restoration Projects 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

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

Species Recovery NWPCC, 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

Developed 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 Estuary Partnership Monitoring Strategy

Monitoring to Date 1989 – 1996: Bi-State $6,000,000: Gives us Baseline at over 500 sites : One time Snapshots gives us quick look –EPA EMAP: $500,000 & USGS BEST: $3,000, : 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 : Council & BPA investment $1,875,000 will give us: –Trend Ability –Ecosystem Classification System –Habitat monitoring (exotic species) –Salmonid Sampling (No toxics) – NOAA matching

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

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
