Status & Trends Overview — An interactive display of status and trends monitoring data with compliance graphics for wild and hatchery adult and smolt salmon. These analyses were prompted by the need to research, monitor, and evaluate compliance pursuant to the Federal Columbia River Power System 2004 Biological Opinion Remand Updated Proposed Action (UPA). The database allows users to assess the compliance using decadal means and decadal trends and includes graphs on Adult Escapement, Adult Passage Counts, CWT SARs, PIT Tag Survival and Travel Time analysis, Harvest Estimates, and hydrosystem conditions (Temperature, Dissolved Gas Percent, Outflow).
Columbia Basin Performance Measures — online data analysis tool generates graphs and summary tables of observed River Conditions and of Fish Exposure to hydrosystem conditions——Dissolved Gas Percent, Dissolved Gas Percent Highest 12hr, Dissolved Gas Percent 12hr Day, Dissolved Gas Percent 12hr Night, Outflow, Spill, Spill Percent, Spill 12hr Day, Spill 12hr Night, Temperature, Temperature 7DADM, and Turbidity——at the major hydroelectric projects on the Columbia and Snake Rivers. Exposure graphs and summary tables are based on observed data retrieved from the Columbia River Data Access in Real Time (DART) database. Fish exposure is based on the total number of fish passing a selected project under user-specified hydrological conditions. Summary tables include statistics for the total run period and the middle 80% of the run period.
Mid Columbia Status for Juvenile and Adult Salmon — collaboration of multiple agencies in the Mid Columbia River region to bring together juvenile and adult salmon information with river conditions for improved management of the region. Data is from Columbia River DART and provided courtesy of Chelan County PUD, Colville Tribes, Douglas County PUD, Grant County PUD, U.S. Geological Survey, Washington State Department of Fish & Wildlife, U.S. Fish & Wildlife Service, U.S. Army Corps of Engineers, and Fish Passage Center.
Ocean Indices — Variations in marine survival of salmon and steelhead are linked to large-scale changes in North Pacific ocean and atmospheric conditions, as well as to local physical and biological conditions off the Oregon and Washington coast. Ocean data can further the understanding of trends in salmon abundance as well as provide input to the development of salmon forecasts.
PIT Tag Survival and Travel Time Analysis — survival and travel time analysis and plots for Columbia Basin PIT-tagged hatchery and wild salmon. The PIT Tag Survival and Travel Time Analysis data includes: 1) Cormack Jolly-Seber Survival estimates for Release to Lower Granite, McNary, and John Day as well as single reach estimates (e.g., Lower Granite to Little Goose) and combined reach estimates (e.g., Lower Granite to McNary); 2) Travel Time estimates for Release to Lower Granite, McNary, and John Day as well as Lower Granite to McNary where appropriate; and 3) Detection Probability estimates at various project locations on the Columbia and Snake rivers.
ROSTER Results — Webpages contain interactive displays of status and trends monitoring data for hatchery adult and smolt salmon. The goal of these summaries is to assist in monitoring salmonid migrations pursuant to the Federal Columbia River Power System 2004 Biological Opinion Remand Updated Proposed Action (UPA). Users can assess graphs of SAR; smolt, ocean, and adult survival; transport-inriver ratios; and 'D', based on PIT-tag data.
Western US Water Temperature Data Analysis — online integration of water temperature distributions with fish distributions. We are developing tools for synthesizing environmental and biological data. Temperature profiles for NW and California streams are developed in a systematic manner and applied to fish presence. Daily water temperatures for the mainstem of the Columbia and Snake rivers are used directly where daily fish distributions are also known. Annual temperature profile parameters are related to surveyed presence/absence information for other streams.
