Downstream Effects: Altered Seasonal Flow Pattern
• Spring Reservoir Refill (Feb-May)– Inflow > outflow – Lower than natural spring flow– PROBLEM: reduced flows affect winter steelhead
outmigration and adult spring Chinook migration; steelhead spawning/incubation flows
• Summer Flow Augmentation (May-Aug)– Outflow > inflow– Higher than natural summer flow– Water quality benefits, rearing habitat
![Page 24: Mindy Simmons US Army Corps of Engineers Dorie Welch, Daniel Spear Bonneville Power Administration](https://reader036.fdocuments.us/reader036/viewer/2022062315/56815863550346895dc5c1e2/html5/thumbnails/24.jpg)
PROBLEM: Providing adequate water downstream of dams for all life stages
Spawning Egg Incubation Redd and eggs out of

Flow Management Actions• Operational changes implemented in 2000
• Minimum mainstem flows
• Tributary flows– Spawning– Incubation– Rearing
• Process for adjusting targets based on water forecasts
• Coordination and in-season management team
• Down-Ramping rates (avoid sudden decreases in flow)
![Page 26: Mindy Simmons US Army Corps of Engineers Dorie Welch, Daniel Spear Bonneville Power Administration](https://reader036.fdocuments.us/reader036/viewer/2022062315/56815863550346895dc5c1e2/html5/thumbnails/26.jpg)
Downstream Effects: Altered Geomorphic Processes
Winter Flood Damage Reduction (Dec/Jan/Feb)– Capture peaks of flood events, slow release– Decreases magnitude of floods
PROBLEM:
Fewer channel-forming flows
+
loss of floodplain connectivity
+
Loss of large wood and gravel from reservoirs
![Page 27: Mindy Simmons US Army Corps of Engineers Dorie Welch, Daniel Spear Bonneville Power Administration](https://reader036.fdocuments.us/reader036/viewer/2022062315/56815863550346895dc5c1e2/html5/thumbnails/27.jpg)
PROBLEM: Downstream Loss of Channel Complexity and Floodplain Connectivity
• Chinook/Steelhead:– Loss of winter rearing habitat;
reduced spawning gravel– Loss of floodplain refugia
• Oregon Chub:– Loss of population connectivity– Loss of habitat

Habitat Restoration Program• On-site actions for Oregon Chub, other species
• Action Agencies will develop an off-site habitat restoration program
• Recovery Plans, Willamette Subbasin Plan, and other habitat assessments will be synthesized to guide restoration work
• Collaborative Habitat Team representing state, tribes, and federal agencies will recommend projects and assist in the prioritization of actions
• Action agencies will work with other habitat programs in the Willamette to identify opportunities and leverage funding where possible
• Complete 2 habitat projects per year starting in 2010

Hatchery Mitigation Program
![Page 34: Mindy Simmons US Army Corps of Engineers Dorie Welch, Daniel Spear Bonneville Power Administration](https://reader036.fdocuments.us/reader036/viewer/2022062315/56815863550346895dc5c1e2/html5/thumbnails/34.jpg)
Hatchery Mitigation Program
• Mitigation for lost production caused by blocked access to habitat upstream of dams
• Current program produces:
• Spring Chinook salmon (part of ESU; integrated)
• Summer steelhead (non-native, segregated program)
• Catchable trout
• NO winter steelhead program (winter steelhead are ESA-listed)
![Page 35: Mindy Simmons US Army Corps of Engineers Dorie Welch, Daniel Spear Bonneville Power Administration](https://reader036.fdocuments.us/reader036/viewer/2022062315/56815863550346895dc5c1e2/html5/thumbnails/35.jpg)
Willamette Basin Hatchery Facilities
5 major hatcheries
• constructed by USACE
• operated by ODFW
• Funded by USACE and ODFW
![Page 36: Mindy Simmons US Army Corps of Engineers Dorie Welch, Daniel Spear Bonneville Power Administration](https://reader036.fdocuments.us/reader036/viewer/2022062315/56815863550346895dc5c1e2/html5/thumbnails/36.jpg)
Downstream Effects: Summer Steelhead Hatchery Program
• Non-native Skamania stock summer steelhead– Popular sport fishery
• Evaluate site-specific effects on ESA-listed winter steelhead
• Modify program in collaboration with ODFW
![Page 37: Mindy Simmons US Army Corps of Engineers Dorie Welch, Daniel Spear Bonneville Power Administration](https://reader036.fdocuments.us/reader036/viewer/2022062315/56815863550346895dc5c1e2/html5/thumbnails/37.jpg)
Downstream Effects: Spring Chinook Hatchery Program
• Use hatchery fish to evaluate reintroduction of Chinook salmon back into their historic habitat above the impassable dams (e.g., NS, SS, McK, MFW)
• Implement new HGMPs for integrated programs– supported by Hatchery
Scientific Review Group– Increase percentage of natural-
origin fish in brood
• Minimize risks on stronghold wild populations (McKenzie)– Manage hatchery-origin
spawners
![Page 38: Mindy Simmons US Army Corps of Engineers Dorie Welch, Daniel Spear Bonneville Power Administration](https://reader036.fdocuments.us/reader036/viewer/2022062315/56815863550346895dc5c1e2/html5/thumbnails/38.jpg)
Action: Leaburg Fish Sorter• McKenzie Chinook is a stronghold wild population
• Leaburg Dam is located on the McKenzie River and owned and operated by Eugene Water & Electric Board (EWEB)
• Action Agencies will construct a sorting facility at the dam to prevent hatchery fish from straying above the dam and into wild fish sanctuary above Leaburg
• Action Agencies will work with EWEB, ODFW and NOAA to design, construct and operate the fish sorter
• BPA lead for funding design and construction (USACE and ODFW fund operation and maintenance)
• Complete by 2014
![Page 39: Mindy Simmons US Army Corps of Engineers Dorie Welch, Daniel Spear Bonneville Power Administration](https://reader036.fdocuments.us/reader036/viewer/2022062315/56815863550346895dc5c1e2/html5/thumbnails/39.jpg)

Quality adult holding habitat
adequate quantities of spawning gravel
most is managed by USFS or BLM
Do we ALSO need access to habitat upstream of dams?
Considerations:
![Page 41: Mindy Simmons US Army Corps of Engineers Dorie Welch, Daniel Spear Bonneville Power Administration](https://reader036.fdocuments.us/reader036/viewer/2022062315/56815863550346895dc5c1e2/html5/thumbnails/41.jpg)
PROBLEM: Inadequate or nonexistent upstream passage facilities
• Upstream passage currently provided only at Foster and Fall Creek dams (trap-and-haul)
• Fish ladders are likely infeasible– High-head dams
– Variable forebay fluctuations
• Existing hatchery facilities designed for broodstock collection
![Page 42: Mindy Simmons US Army Corps of Engineers Dorie Welch, Daniel Spear Bonneville Power Administration](https://reader036.fdocuments.us/reader036/viewer/2022062315/56815863550346895dc5c1e2/html5/thumbnails/42.jpg)
SOLUTION: Use Willamette Basin Hatchery Fish Facilities as “trap-and-haul” for adult fish
Adult Collection
DEXTER DAM
Adult Sorting; load on to truck for transport
SOLUTION: Use hatchery spring Chinook to evaluate potential for reintroduction in upstream habitat
![Page 43: Mindy Simmons US Army Corps of Engineers Dorie Welch, Daniel Spear Bonneville Power Administration](https://reader036.fdocuments.us/reader036/viewer/2022062315/56815863550346895dc5c1e2/html5/thumbnails/43.jpg)
Upstream Fish Passage Actions
• Continue adult “outplanting” program
• Construct Trap at Cougar Dam (McK):2009
• Improve or replace adult fish traps:Minto (N. Santiam): 2012Foster (S. Santiam): 2013Dexter (Middle Fk Willamette):
2014Fall Creek: 2015
• Develop 4 to 6 adult release sites above reservoirs by 2012Outplanting adult spring
Chinook also provides prey base for bull trout

PROBLEM: Downstream Passage is Challenging
Regulating Outlets (“spill”)
Power Turbines
Spill gates (rarely used)
• Long reservoirs
• Predators
• Deep intakes to passage routes (very little surface spill)

• Measures to improve passage through reservoirs and dams until permanent facilities are built– Fall Creek drawdown for Chinook outmigration– Test other measures: reservoir drawdown, pulsing flows, spill,
other outlets– Implement feasible alternatives (“simple” by 2009; more
“complex” by 2011)
• Head-of-Reservoir juvenile collection prototype– Evaluate feasibility – complete by end of 2010– Construct prototype by 2014– Biological and physical evaluations 2015 & 2016– If effective, include in design alternatives for downstream
passage at other Project dams
• Evaluate fish passage survival, injury, delay, timing and distribution at 8 Project dams and reservoirs, 2008 - 2015
Biological Opinion Actions: Step-wise Approach to Downstream Passage

Biological Opinion Actions: Step-wise Approach to Downstream Passage
• Downstream fish passage facilities Construction complete by:
• Cougar - 2014
• Lookout Point/Dexter - 2021
• Detroit/Big Cliff - 2023
• Evaluate for use at additional dams
• Analyze feasibility, alternatives, design through the COP study

Configuration Operation Plan“COP”
• Reconnaissance Phase Study due 2009• Feasibility phase to assess alternatives• All major structural modifications will be
evaluated for:– Biological benefit
– Technical feasibility
– Economic viability
– Consistency with overall recovery strategies
![Page 51: Mindy Simmons US Army Corps of Engineers Dorie Welch, Daniel Spear Bonneville Power Administration](https://reader036.fdocuments.us/reader036/viewer/2022062315/56815863550346895dc5c1e2/html5/thumbnails/51.jpg)
Research, Monitoring & Evaluation
• Willamette is data-poor relative to mainstem Columbia– Very little monitoring
infrastructure• Developing comprehensive
program, to feed into COP– Site-specific field studies– Coordinated through WATER
• Currently included in AFEP Annual Review– Expanded outyear efforts in
separate process in Willamette

Funding Strategy• Most large structural modifications will be funded out of the Columbia
River Fish Mitigation Fund (CRFM)
• Authority: Original project authorities, such as 1950 Flood Control Act (as is the original CRFM Project)
• Proposal to use CRFM appropriation made with 2008 budget submittal to Congress (including $800k in funding to initiate actions)
• Future Corps budget proposals will account for most critical needs to meet BiOp commitments in both programs
• The System Configuration Team (SCT) provides input on priorities for Columbia/Snake program – WATER group will perform a similar function for the Willamette
component

Need downstream habitat for rearing
Different effects on fishWillamette dams different than mainstem Columbia dams
The Willamette Project Summary
Need to use hatchery program to evaluate reintroduction into spawning habitat upstream of
dams

Evaluate feasibility of long-term actions
Short-term improvements and actions:
•Habitat
•Temperature
•Flow operations
•Hatcheries
Long-term structural modifications may be critical to
success
The Willamette Project Approach
Improve hatchery collection facilities as trap-and-haul
