Data and estimating missing data for the Puget Sound Chinook salmon ESU 5-year status review.

This report documents the data used for the National Marine Fisheries Service’s 2010 5-year status review of the Puget Sound Chinook Salmon Evolutionarily Significant Unit (ESU) populations (Ford 2011, NMFS 2011). It also documents the methods used to estimate values for missing years of data in order to develop the complete time series needed for cohort run reconstruction. The length of the time series for each population was determined by the availability of spawning abundance estimates. Data were supplied by state and tribal comanagers, either in reports or directly as the result of the public request for data as part of the 5-year status review of the Puget Sound Chinook Salmon ESU (NMFS 2010). The status review focused primarily on abundance and productivity of the 22 populations identified by the Puget Sound Technical Recovery Team (PS TRT) and used in the recovery plan (Ruckelshaus et al. 2006, SSDC 2007). In Table 1 through Table 22 of this report, data supplied by comanagers or obtained from reports are in normal font and estimates for missing data used in this analysis are in boldface. Methods for estimating missing data are provided in detail in the descriptions of each watershed population (22 populations in the 12 subsections of the Population-specific Data and Methods section).
