CSS SARs by Study Category
This query returns SARs for transported smolts (SAR_TRANS), in-river smolts not detected at LGR, LGS, or LMN (SAR_C0), and in-river smolts detected at one or more of the Snake River collector dams (SAR_C1) for the selected species and migration year range.

Step 1. Select Species: All Species All Chinook Hatchery Chinook Wild Chinook All Steelhead Hatchery Steelhead Wild Steelhead Hatchery Sockeye

Step 2.  Enter desired migration year in yyyy format: to Note: This query includes data for the years 1994 to 2009.

Step 3.  Submit Form or Reset

NOTES:

• The SAR formulas for Snake River groups during migration years both with and without pre-assignment are covered in Chapter 4 of the CSS 2010 Annual Report. Snake River wild and hatchery Chinook and wild steelhead were not pre-assigned before 2005 and were pre-assigned thereafter. Snake River hatchery steelhead through 2007 were not per-assigned and were pre-assigned thereafter.
• When sarC0 field is blank, it is assumed to equal sarC1 (as occurs in 2001).
• When sarC1 field is blank, one in-river SAR was estimated from the combined in-river groups because of small sample sizes. This was calculated as (C0 + C1 adults) / (C0 + C1 smolts).
