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).
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.
