The dataset ds180_Chinook_pnts is a product of the CalFish Adult Salmonid Abundance Database. Data in this shapefile are collected from point features, such as dams and hatcheries. Some escapement monitoring locations, such as spawning stock surveys, are logically represented by linear features. See the companion linear feature shapefile ds181_Chinook_ln for information collected from stream reaches.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 Databases tabular data is currently stored.

This project examines the factors influencing fish populations including habitat, harvest, hatcheries, hydropower system operations, and climate change. It seeks to estimate impacts of these factors on Wenatchee River basin spring Chinook salmon through the use of the Shiraz life cycle model parameterized for this fish population. An evaluation of a suite of habitat restoration actions will be conducted, a reparameterized model to incorporate supplementation effects will estimate the impacts on wild fish from hatchery operations, and the influence of climate change as estimated from several bracketing Global Climate Models (and their basin impacts determined via DHSVM modeling) will be examined. The Shiraz and climate modeling work is led by Dr. Jon Honea at Emerson College (Boston, MA), an external collaborator who began this work in a post-doctoral position at the NWFSC. And, we are using life cycle modeling in an evaluation of benefit/cost of suites of freshwater habitat actions. Model.

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.

Tabular dataset containing all available age, sex, and length information of Chum salmon and Chinook salmon sampled at the Gisasa Weir by the U.S. Fish and Wildlife Service between 1995 and 2023. Raw data were collected on physical datasheets which are stored at the Northern Alaska Fish and Wildlife Conservation Office, Fairbanks with Jeremy Carlson. Raw data were then manually transcribed to Microsoft workbooks. Sex was determined externally using visual clues such as snout shape and size. Length was measured from fork to mid-eye with a measuring board to the closest 5 mm. Strata refers to the potion of the run the fish was sampled during. Strata data is based on the size of the population rather than date since the salmon run does not start on one specific date year by year. Scales were also taken and placed on a gum card for aging. One scale was taken for all sampled Chum salmon and 3 scales were taken for all sampled Chinook salmon. NA refers to missing data.

This data is out of date, no longer updated, and may contain inaccurate information, please see Salmonid Population Monitoring Areas - California - CMP [ds3001].The California Monitoring Plan is the most comprehensive program to date that provides a complete understanding of Californias salmon and steelhead populations, utilizing statistically-rigorous modeling in combination with a variety of in-river sampling and surveys methods. CDFW and NOAA Fisheries are leading the implementation of this Plan from Californias northern border with Oregon south to its board with Mexico. This monitoring strategy was designed to estimate populations of anadromous salmonids in coastal streams, and is being currently expanded to include the anadromous rivers of Central Valley.For more detail on the Klamath-Trinity River systems, visit the links below.https://www.wildlife.ca.gov/Conservation/Fishes/Chinook-Salmon/Anadromous-Assessment
