ROSTER Performance Measures

ROSTER Results: These 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.

Select the desired data by one of the following categories: Performance Measure, Species, Province, Subbasin, HUC3, HUC4, or Hydroelectric Project. Each category will provide further categories from which to choose.

Measure Descriptions

Adult Survival by Release Year

Average perceived upriver adult survival from Bonneville Dam to Lower Granite Dam by release (migration) year. Results include data from multiple return years. For steelhead, "jack" means all age-1-ocean fish, including both males and females.

Formula:

Adult Survival by Return Year

Average perceived upriver adult survival from Bonneville Dam to Lower Granite Dam by return year. Includes adult data from multiple release (migration) years. For steelhead, "jack" means all age-1-ocean fish, including both males and females.

D for LGR

Ratio of post-Bonneville Dam survival for fish transported at Lower Granite Dam relative to post-Bonneville survival for non-transported fish. For steelhead, "jack" means all age-1-ocean fish, including both males and females.

D for LGS

Ratio of post-Bonneville Dam survival for fish transported at Little Goose Dam relative to post-Bonneville Dam survival for non-transported fish. For steelhead\ , "jack" means all age-1-ocean fish, including both males and females.

Formula:

Ocean Survival

Bonneville Dam-Bonneville Dam survival for non-transported fish; includes ocean survival. For steelhead, "jack" means all age-1-ocean fish, including both males and females.

Formula:

SAR

Survival from Lower Granite Dam to Lower Granite Dam, including transported and non-transported fish. For steelhead, "jack" means all age-1-ocean fish, including both males and females.

Formula:

Smolt Survival (ROSTER)

Juvenile inriver survival from Lower Granite Dam to Bonneville Dam. For steelhead, "jack" means all age-1-ocean fish, including both males and females.

Formula:

Systemwide D

Ratio of post-Bonneville Dam survival for transported fish relative to post-Bonneville Dam survival for non-transported fish. Incorporates all transport sites. For steelhead, "jack" means all age-1-ocean fish, including both males and females.

Formula:

Systemwide T/I

Ratio of SAR from Lower Granite Dam to Lower Granite Dam with transportation system, relative to hypothetical SAR without transportation system. Incorporates all transport sites. For steelhead, "jack" means all age-1-ocean fish, including both males and females.

Formula:

T/I for LGR

Ratio of SAR from Lower Granite Dam to Lower Granite Dam of smolts transported at Lower Granite Dam, relative to non-transported smolts. For steelhead, "jack" means all age-1-ocean fish, including both males and females.

Formula:

T/I for LGS

Ratio of SAR from Little Goose Dam to Lower Granite Dam of smolts transported at Little Goose Dam, relative to non-transported smolts. For steelhead, "jack" means all age-1-ocean fish, including both males and females.
