IMPLEMENTATION

15-year Implementation timeframe

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

PROBLEM: Providing adequate water downstream of dams for all life stages

Spawning Egg Incubation Redd and eggs out of

water

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)

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

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

Willamette River Planning Atlas (PNW Ecosystem Research Consortium)

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

Willamette Project

Hatchery Mitigation Program

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)

Willamette Basin Hatchery Facilities

5 major hatcheries

• constructed by USACE

• operated by ODFW

• Funded by USACE and ODFW

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

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

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

How do the Action Agencies How do the Action Agencies move forward?move forward?

Can we JUST improve habitat downstream of projects?• Flows and operations• Improve temperatures• Habitat improvement and floodplain restoration• Hatchery improvements

Altered Altered downstream downstream habitathabitat

ESA Sec 7 Consultations

Recovery Planning

Dams blocked Dams blocked access to historical access to historical spawning habitatspawning habitat

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:

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

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

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

Cougar Fish Trap Plans

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)

Willamette Project “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

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
