Appendix A. Site specific information on sample analysis and Sr isotope values.
TABLE A1. Locations and 87Sr/86Sr values for baseline data collected throughout Big Creek and the greater MFSR watershed. Big Creek water samples were collected over multiple field seasons to establish baseline isotopic signatures for the entire basin. Major tributaries to Big Creek, the South Fork of the Salmon River (SFSR) and MFSR, and major tributaries of the MFSR upper sub-basin are listed in italics, and distinguishable spawning locations are denoted with asterisks. Standard error of the mean (SE) is calculated from the measurement of 150–200 ratios of an individual sample run on the mass spectrometer.
