Long Term Vision For Coho
Reintroduction
“To re-establish naturally spawning coho populations in mid and upper Columbia
tributaries to biologically sustainable levels, which provides significant harvest in
most years”
Upper Columbia Tributaries
• Historical Abundance (Mullan 1983)
– Wenatchee: 6,000-7,000
– Entiat: 9,000-13,000
– Methow: 23,000-31,000
Coho Salmon
Methow River 1910, Mullan (1992)
Project Undertaking: An Uphill
Battle
• Challenges and limitations
• Identify evaluations needed to study interactions
with endemic and sensitive species
Feasibility Study Goals
1. To determine if a local broodstock could be
developed from lower Columbia River stocks
2. Initiate natural production
3. Answer critical uncertainties regarding species
interactions.

Feasibility Phase
Next Step
• Create a comprehensive
long-term plan for coho
reintroduction
– Progress brood
development towards
“preferred habitats”
• Modeling to determine
estimate capacity
– Focus on decreasing
domestication while
increasing population
fitness

Target PNI > 0.5
Proposed Phased Approach
An adaptive management strategy to
reintroduction
• Broodstock Development Phases
• Natural Production Phases
Monitoring and Evaluation
• Project Performance
Indicators
• Species interactions
• Adaptability to local
conditions
Program’s Future
• Several studies being
implemented:
– Monitor natural origin juvenile
freshwater performance
• Productivity
• Distribution
– Study the rate of divergence
between LCR vs MCR
• Allele frequency over time
• Phenotypic adaptation
– Adult outplant study
• Relative reproductive success
– Measuring phenotypic attributes
of upper basin adults at a lower
trap facility
– Parental Crosses
• Measure progeny’s adult return rates
based on mating schemes

March 2012: Completed the Final
Environmental Impact Statement
(FEIS)
July 2012: Received a Record of
Decision (RoD) from BPA
Fall 2012: Revising Biological
Assessments (BAs) with
USFWS/NMFS to initiate Section

Fall 2013: Begin Natural
Production Implementation Phase
(NPIP) in the Methow subbasin
Project Benefits
• Provide increased cultural and socio-economic
value to the region
• Opportunity to study the local adaptation
process and at what rate it can occur
• Supplying marine nutrients at the onset of winter
• Increase abundance of a keystone species
within ecological communities
