Smolt-to-Adult Survivals Smolt-to-Adult Survivals
- CSS SARs by study category CSS SARs by study category- This query returns Lower Granite (juvenile)-to-Lower Granite (adult) SARs (without jacks for Chinook) for transported smolts, in-river smolts not detected at transportation sites (C0), and in-river smolts detected at one or more transportation site (C1), as presented in Appendix A of the CSS Annual Reports.
- Overall Annual SARs for Zones in the Snake or Columbia Rivers Overall Annual SARs- This query returns annual overall SARs for all groups of Snake, Middle Columbia, and Upper Columbia Chinook, steelhead, and sockeye that are presented in the 'Annual Overall SARs' appendix of CSS Annual Report.
- CSS SR, TIR, and D CSS SR, TIR, and D- This query returns three metrics estimated by the CSS for Snake River spring/summer Chinook, steelhead, sockeye, and subyearling fall Chinook. These metrics include: 1) juvenile in-river survival (SR) for the Lower Granite Dam to Bonneville Dam reach, 2) Transport/In-River SAR Ratios (TIR), and 3) differential delayed effects of transportation in relation to in-river out-migrants (D), as presented in Appendix A of the CSS Annual Reports.
- CSS returning adult age composition query CSS returning adult age composition query- allows the user to query for the age compositions of returning adults used in the CSS 10 Year Report by choosing a species, source location, and year data. Data tables and graphs are returned.
- Number of smolts and returning adults by study category Number of smolts and returning adults by study category- allows the user to query the estimated number of smolts per study category and adult count used to generate SAR estimates with associated 90% confidence interval and the number of returning adults per study category for PIT-tagged wild and hatchery Chinook and steelhead. Fish traverse the hydro system by (1) passing in-river through the Snake River collector dams in a non-bypass channel route (spillways or turbines), (2) passing in-river through the dam's bypass channel, or (3) passing in a truck or barge to below Bonneville Dam. These three ways of hydro system passage define the CSS study categories C0, C1 and transported (TRAN), respectively. In this query data tables and graphs are returned. NOTE: The numbers of smolts are those used in study category SAR estimation and do not necessarily represent their relative proportions in the run at large. The proportions of study categories in the run-at-large are published in the CSS Annual Report.
