Assessment also indicated
Need improvements in most threat sectors
Improve HABITAT conditions in freshwater and estuary
Reduce impacts of• FLOOD CONTROL / HYDROPOWER• HATCHERY• COMPETITION and PREDATION
Improvements needed to maintain current status• Given limited resources prioritize actions• Adopt a long-term perspective
![Page 12: draft Upper Willamette River Conservation and Recovery Plan for Chinook Salmon and Steelhead](https://reader036.fdocuments.us/reader036/viewer/2022062802/56814589550346895db26e87/html5/thumbnails/12.jpg)
Major Strategies and Actions
Flood Control/Hydropower Actions
• Willamette Project BiOp actions, FERC agreements• upstream and downstream passage • temperature control and flow modification• revetments and other physical habitat (mainstem projects)
• FCRPS BiOp actions for estuary impacts
Freshwater Habitat Actions
• ODEQ TMDL Water Quality actions • Best Management Practices, State/Federal guidelines• Voluntary protective and restoration actions
Estuarine Habitat Actions
• NMFS Estuary Recovery Plan
![Page 13: draft Upper Willamette River Conservation and Recovery Plan for Chinook Salmon and Steelhead](https://reader036.fdocuments.us/reader036/viewer/2022062802/56814589550346895db26e87/html5/thumbnails/13.jpg)
Major Strategies and Actions (continued)
Hatchery Actions • Reduce hatchery fish on spawning grounds• Examine/reduce predation/competition on juveniles• As conditions improve, re-introduce above barriers• Manage as “wild fish emphasis areas”
Harvest Actions
• Manage current regimes in existing Fishery plans
Other Species Actions
• NMFS Estuary Recovery Plan• Research, Monitoring, and Evaluation for predation impact
in Willamette and subbasins

Mainstem Willamette River Land Use Management
Strategy: Implement Willamette basin TMDL actions, rural and urban BMP’s, and other land-use actions to address multiple Limiting Factors
Actions include:• Temperature TMDL WQMP actions: increase riparian
vegetation/shade function
• Strengthen/implement BMP’s: reduce inputs/runoff of non-point source of chemicals
• Pesticide/nutrient TMDL WQMP actions: reduce sourcing of runoff from urban, industrial, rural, and agricultural practices
• Promote incentives to private landowners: protect/restore riparian areas and high-quality off-channel habitats not covered by actions in other plans

Strategy: Implement the suite of Willamette Project BiOp flow and habitat actions to address multiple Limiting Factors
Actions include Willamette Project BiOp: • Revetment modification/reduction and restoration
actions:• improve the amount, complexity, diversity, and connectivity of
riparian, confluence, and off-channel habitats
• Flow actions:• increase occurrence of peak flows to maintain and create
habitat, increased channel complexity and habitat diversity
• meet salmon and steelhead rearing and migration flow targets

Habitat Principals and PrioritiesProtect/enhance viability of multiple listed populations
Protect habitat with these traits • natural production areas (subbasins) (PRODUCTIVITY)• supports major life history strategies (DIVERSITY)• contributes to other viability traits (SPATIAL STRUCTURE)
Enhance/restore habitat and natural processes
• increase life-stage survival (ABUNDANCE), reproductive success, and connectivity
Fix specific habitat limiting factors
• large pay-off to closing viability gaps between current and desired future status

Mainstem Willamette Habitat Projects Considerations and Discussion
A comprehensive and workable shared vision and strategy?
What to protect and restore?• “Ecosystem Services” the conceptual umbrella for goals?
• What level of functional ecosystem process does this imply?
• Are we all on the same page for priorities and time scales?
A structured framework to accomplish this?
A metric to measure progress accomplishment?• Can projects be scoped large enough to elicit a measurable
response?
Balance of willing opportunities (easements/ acquisitions) and regulations?
