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.
For detailed discussions of these data and how overall SARs are estimated, see the 'Patterns in Annual Overall SARs' and 'Estimation of SARs, TIRs and D for Snake River Subyearling Fall Chinook' chapters of the most recent CSS Annual Report (http://www.fpc.org/documents/CSS.html).

Year of PIT-tagged smolt out-migration
Number of smolts in the SAR estimate.
For Dam_to_Dam SARs, this is typically an estimate of the number of smolts arriving at a given dam based on estimates of survival from release site to that dam (LGR, MCN, BON, JDA, or RRE).
For Release_to_BOA SARs, this is the total number of PIT-tagged smolts released at the release site.
Smolt-to-Adult Return (SAR) estimate without jacks (1-salts) included. This only pertains to Chinook and is not provided for queries of Steelhead or Sockeye.
90% lower limit bootstrap confidence interval for SAR (without Jacks). This only pertains to Chinook and is not provided for queries of Steelhead or Sockeye.
90% upper limit bootstrap confidence interval for SAR (without Jacks). This only pertains to Chinook and is not provided for queries of Steelhead or Sockeye.
Smolt-to-Adult Return (SAR) estimate with jacks (1-salts) included
90% lower limit bootstrap confidence interval for SAR (with Jacks).
90% upper limit bootstrap confidence interval for SAR (with Jacks).
