Note: Model estimates were calculated with other variables held constant at their means except for Clams, which was held constant at ‘present’ (i.e., not ‘absent’). SRT is Sacramento River residence time (days), SFM is Sacramento River volume (m3 s−1) past Martinez (log10-transformed), SJRT is San Joaquin River residence time (days), SJFM is San Joaquin flow past Martinez (log10-transformed)
