Status and 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). The tool features a Google Maps Interface to provide
map based searches of the monitoring database. This allows
users to search our data offerings by Province, Subbasin, or dam using
the power of Google Maps and Google Earth. From the Status and
Trends Overview web page, click on the "Map" option to access the
Google Maps Interface. |

Adult Escapement
— adult escapement has been pooled into various spawning aggregations
for spring chinook, summer chinook, spring/summer chinook, fall chinook,
sockeye, and steelhead based on interim target abundances established by
the National Marine Fisheries Service (NMFS) Biological Review Team (BRT)
in their Draft Report
of Updated Status of Listed ESUs of Salmon and Steelhead. |

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.

Center. |

Northwestern Regional 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 regional
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. |
 |
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. |

Smolt-to-Adult Ratio (SAR) Estimates
for Coded Wire Tag — online data analysis and plots of
SARs for Coded Wire Tag (CWT) hatchery salmon from Oregon, Washington and
Idaho. The analyses were prompted by the need to research, monitor, and
evaluate SARs pursuant to the Federal Columbia River Power System 2000 Biological
Opinion Reasonable and Prudent Alternative (RPA). The analysis includes
CWT returns from over 100 hatcheries across the Northwest region for all available
years with annual updates of analyses. The CWT release and recovery data
analyzed were obtained from the Regional
Mark Processing Center. For each hatchery and stock, annual bar charts
illustrating SARs are plotted and a table summarizing statistics per tag
code is provided. |
