Appendix F. Table showing upstream and downstream concentrations of TN and TP. Shown are averages of TP and TN concentrations across all years and samples for the given stretch or time period.

TABLE F1. Upstream and downstream concentrations of TN and TP. Shown are averages of TP and TN concentrations across all years and samples for the given stretch or time period. In streams with salmon, “During” represent samples collected during the time period when salmon were present in the stream. In streams without salmon, “During” represents samples collected in August, the period when salmon are spawning in streams with salmon. “Upper” samples were collected upstream of spawning salmon, while “Lower” samples were from the base of the stream.
