This population historically migrated as subyearling smolts, but in recent years, the yearling life history has become more common. Environmental conditions associated with dams and reservoirs might be exerting strong selection for alteration of life history traits that evolved over millennia. This project attempts to determine the extent to which these life history changes are due to evolution (genetic change) as opposed to phenotypic plasticity (non-genetic response to different environmental conditions).

The objective of this study is to quantify population, community, and ecosystem level changes as a result of salmon recolonization of the Cedar River, WA above Landsburg Dam. The dam was installed in 1901, blocking the upstream migration of adult salmon and steelhead from about 43 km of river habitat. A fish ladder was installed in 2003 to allow adult salmon passage. We collected baseline data on water chemistry, habitat, and fish populations including resident trout and sculpin populations in 2000-2002. These field surveys have been ongoing since 2000. A mark-recapture study in Rock Creek, the largest tributary available to salmon, was started in 2004 and ended in 2010 to quantify growth, movement, and survival of juvenile coho and resident trout. Two experimental stream studies conducted to quantify salmon carcass effects on resident organisms. PIT data of juvenile coho and resident trout in Rock Creek.

The dataset ds181_Chinook_ln is a product of the CalFish Adult Salmonid Abundance Database. Data in this shapefile are collected from stream sections or reaches where Chinook population monitoring occurs and that are best represented by linear features. Some escapement monitoring locations are logically represented by point features, such as dams and hatcheries. See the companion point feature shapefile ds180_Chinook_pnts for information collected from point locations.The CalFish Abundance Database contains a comprehensive collection of anadromous fisheries abundance information. Beginning in 1998, the Pacific States Marine Fisheries Commission, the California Department of Fish and Game, and the National Marine Fisheries Service, began a cooperative project aimed at collecting, archiving, and entering into standardized electronic formats, the wealth of information generated by fisheries resource management agencies and tribes throughout California.The data format provides for sufficient detail to convey the relative accuracy of each population trend index record yet is simple and straight forward enough to be suited for public use. For those interested in more detail the database offers hyperlinks to digital copies of the original documents used to compile the information. In this way the database serves as an information hub directing the user to additional supporting information. This offers utility to field biologists and others interested in obtaining information for more in-depth analysis. Hyperlinks, built into the spatial data attribute tables used in the BIOS and CalFish I-map viewers, open the detailed index data archived in the on-line CalFish database application. The information can also be queried directly from the database via the CalFish Tabular Data Query. Once the detailed annual trend data are in view, another hyperlink opens a digital copy of the document used to compile each record.During 2010, as a part of the Central Valley Chinook Comprehensive Monitoring Plan, the CalFish Salmonid Abundance Database was reorganized and updated. CalFish provides a central location for sharing Central Valley Chinook salmon escapement estimates and annual monitoring reports to all stakeholders, including the public. Annual Chinook salmon in-river escapement indices that were, in many cases, eight to ten years behind are now current though 2009. In some cases, multiple datasets were consolidated into a single, more comprehensive, dataset to more closely reflect how data are reported in the California Department of Fish and Game standard index, Grandtab.Extensive data are currently available in the CalFish Abundance Database for California Chinook, coho, and steelhead. Major data categories include adult abundance population estimates, actual fish and/or carcass counts, counts of fish collected at dams, weirs, or traps, and redd counts. Harvest data has also been compiled for many streams.This CalFish Abundance Database shapefile was generated from fully routed 1:100,000 hydrography. In a few cases streams had to be added to the hydrography dataset in order to provide a means to create shapefiles to represent abundance data associated with them. Streams added were digitized at no more than 1:24,000 scale based on stream line images portrayed in 1:24,000 Digital Raster Graphics (DRG).The features in this layer represent the location for which abundance data records apply. In many cases there are multiple datasets associated with the same location, and so, features may overlap. Please view the associated datasets for detail regarding specific features. In CalFish these are accessed through the "link" field that is visible when performing an identify or query operation. A URL string is provided with each feature in the downloadable data which can also be used to access the underlying datasets.The Chinook data that is available from the CalFish website is actually mirrored from the StreamNet website where the CalFish Abundance

The goal of the tidal-fluvial estuary study is to determine the estuary's contribution to the spatial structure and life history diversity of Columbia River salmon stocks and the implications for estuary restoration. The study targets salmon use of tidal-fresh habitats in the estuary from Rkm 75 to Bonneville Dam, and addresses four primary objectives: 1. Characterize the temporal and spatial distribution of Chinook salmon genetic stock groups throughout the estuary (March 2010 - March 2012). 2. Determine stock-specific habitat use, life histories, and performance of juvenile salmon in key habitat complexes to fill data gaps in the tidal fluvial reaches of the estuary (2012-2016). 3. Monitor juvenile salmon life histories and their contributions to adult returns in selected estuary tributaries, including tributary examples where tidal habitats have been restored (2012-2018). 4. Evaluate estuary restoration needs for recovery of all salmon ESUs and account for projected effects of climate change through application of a salmon life-cycle model (2011-1015). The study, funded by the U.S. Army Corps of Engineers, involves a large team of researchers organized by NOAA Fisheries, including researchers from the Oregon Health and Sciences University, University of Washington, and Washington Department of Fish and Wildlife. The study addresses critical uncertainties identified in the research, monitoring, and evaluation (RME) program for the Federal Columbia River Estuary Program (FCREP). The Estuary Program is intended to conserve and restore the estuary ecosystem to improve the performance of listed salmonid populations. Products from the tidal-fluvial study will include: 1. Descriptions of stock-specific temporal and spatial distributions of Chinook salmon throughout the estuary. 2. Estimates of variations in Chinook salmon stock composition and stock-specific growth, food habits, consumption rates, and bioenergetic efficiencies within selected tidal-fluvial habitats. 3. Estimated contributions of estuarine life histories among returning adult Chinook salmon from selected populations throughout the Columbia River Basin. 4. A hydrological model quantifying the dynamics of rearing habitat opportunities for juvenile salmon at estuary reach and habitat scales. 5. Improved life-cycle models to account for the estuarine life histories of juvenile salmon and estimating the potential effectiveness of estuary restoration actions on the recovery and viability of selected salmon stocks. These results will directly address information needs to support estuary actions specified in the Federal Columbia River Power System (FCRPS) Biological Opinion for the Columbia River. The tidal-fluvial estuary study is part of an ongoing estuary research program initiated in 2002. The current study expands upon earlier research conducted in the lower 100 km of the estuary from 2002 to 2008. Although all objectives will be addressed by 2018 to correspond with a review of progress implementing the FCRPS Biological Opinion, some sampling activities may extend beyond this date to allow brood-year reconstruction of estuary contributions to adult returns in selected streams (Objective 3). Bimonthly genetic stock group distribution for juvenile Chinook Salmon collected from 3 habitats each from 6 tidal-fluvial estuary reaches and monthly fish species composition, abundance, and length:weight; Chinook salmon life history and genetic stock ID.

1) The purpose of this project is to measure changes in juvenile salmon habitat occurrence and health following restoration activities at the Mirror Lake Complex and Horsetail Falls in the Lower Columbia River and estuary. Parameters measured include habitat conditions such as vegetation, water temperature, and dissolved oxygen; salmon diet and prey availability; weight, length, growth rate, lipid content, genetic stock, and chemical contaminant exposure. 2) Lyndal Johnson (NWFSC FTE) is the project lead, and other primary staff involved are Sean Sol and Paul Olson (NWFSC FTEs) and Kate Macneale (NWFSC term employee), but the project also involves other NWFSC FTEs, other term employees, contractors, and staff from other programs (Environmental Chemistry) and Divisions (FE, CB), as well as staff from collaborating agencies (e.g., the Lower Columbia River Estuary Partnership). 3) The project involves field surveys in which parameters measured include habitat conditions such as vegetation, water temperature, and dissolved oxygen; salmon diet and prey availability; weight, length, growth rate, lipid content, genetic stock, and chemical contaminant exposure. 4) Specific products to be produced include annual reports for the Lower Columbia Estuary Partnership, and manuscripts in peer-reviewed journals. 5) Specific audiences include (but are not limited to) the Bonneville Power Administration and other federal, state, and local agencies involved with salmon recovery and environmental management in the Columbia Basin (e.g., EPA, Washington Department of Ecology, Oregon Department of Environmental Quality, the City of Portland), the NMFS regional office, and other agency and academic scientists. 6) This is a stand-alone project, but it is also a component of a larger action effectiveness monitoring program overseen by the Estuary Partnership. 7) This is an ongoing project with a soft completion deadline; however, there are specific tasks to be completed on a yearly basis. Chinook salmon genetic stock identification.
