Status classifications differ by state. See definitions listed in Appendix B.
HRE = High Risk of Extinction; MRE = Moderate Risk of Extinction.
Months in all capitals have the highest number of smolts in the estuaries.
HS = Pacific harbor seal; CSL = California sea lion; SSL = Stellar sea lion.
MS = Main Stem; NF = North Fork; SF = South Fork; MF = Middle Fork.
