Description
- Abstract: In the Willamette Basin upstream of Willamette Falls (Figure 1), there are four distinct spring
Chinook salmon hatchery programs (North Santiam [Stock 21], South Santiam [Stock 24],
McKenzie [Stock 23], and Middle Fork Willamette [Stock 22]) that are managed for integrated
harvest augmentation as part of the Willamette Valley Hatchery Mitigation Program. These
hatchery stocks, as well as all naturally spawned spring Chinook salmon in the Upper Willamette
Basin, are included in the Upper Willamette River Evolutionary Significant Unit (ESU).
The Upper Willamette Summer Steelhead Hatchery Program is managed to provide fish for sport
fisheries and to replace loss of fisheries caused by habitat and passage loss/degradation in the
Willamette and other lower Columbia basins. The hatchery program currently includes annual
smolt releases into the North Santiam, South Santiam, McKenzie, and Middle Fork Willamette
rivers. Lack of access to historical habitat and degradation of remaining habitat below the dams,
especially in the North and South Santiam (the “core” populations) are the key limiting factors
shared between winter steelhead and spring Chinook salmon. In addition, summer steelhead are
not native to the Willamette Basin upstream of Willamette Falls and a third, unique, limiting
factor is the potential for competition, predation and genetic introgression from out-of-ESU
hatchery fish interacting with and spawning in the wild with the native winter-run(Johnson et al.
2013). Summer steelhead were first introduced to the South Santiam River as mitigation for lost
winter steelhead production in areas inundated by Foster and Green Peter reservoirs. The scope
of work actually directed towards risks posed by summer steelhead is much smaller than that
directed towards issues faced by spring Chinook salmon. The Willamette Project Biological
Opinion (BiOP; NMFS 2008) required the USACE to collect information to describe the nature
and extent of these potential effects but beyond relatively small-scale studies often integrated
into much larger studies involving spring Chinook salmon, more focused work on steelhead will
only follow commitment of significantly more effort and funds.
This report fulfills a requirement under Task Order W9127N-12-2-0004-1009 covering activities
of May 2013–June 2014, that were implemented by ODFW on behalf of the Corps to assist with
meeting requirements of the reasonable and prudent alternatives (RPAs) and measures prescribed
in the Willamette Project Biological Opinion (BiOp) of July 2008 (NOAA 2008). The Corps
provided funding to continue ongoing monitoring activities and initiate long-term planning. The
conceptual relationship between spring Chinook salmon prioritized objectives, RPAs, and 2013
work tasks is depicted in Figure 2. In future work, the intent is to expand the conceptual
framework provided in Figure 2 and develop specific numerical goals in terms of, for example,
adult returns desired per subbasin. A detailed list of tasks associated with the work is provided in
Appendix 1.
-
- Purpose: The ultimate goal of ODFW’s Hatchery Research, Monitoring and Evaluation (HRME) program
is to inform decisions on operation of the USACE Willamette Valley Hatchery Mitigation
Program so that mitigation goals are met while minimizing negative impacts on naturallyproduced,
listed species and promoting their conservation and recovery. Progress towards that
goal will follow achievement of three overarching objectives:
1. Develop and maintain hatchery broodstocks to meet harvest goals and assist with
implementation of the Upper Willamette Conservation and Recovery Plan for Chinook
Salmon and Steelhead (National Marine Fisheries Service [NMFS] and ODFW 2011),
while complying with the existing genetic guidelines (Hatchery Genetic Management
Plans);
2. Rear and release high quality hatchery fish to minimize impacts on naturally produced
fish and promote conservation and recovery of listed species;
3. Manage adult returns to minimize impacts on naturally produced populations and to aid
in recovery goals.
