Appendix D. A table showing the proportion of nutrients that were dissolved.

TABLE D1. The proportion of nutrients that were dissolved. Values shown are averages of the dissolved proportion of TP and TN for a subset of streams. No statistical tests were run due to small sample sizes. All samples were taken from lower reaches. Dissolved proportions were calculated by comparing nutrient concentrations in unfiltered water to nutrient concentrations in water filtered through a 0.2 µm cellulose acetate filter to remove particulate nutrients. See Appendix B for description of periods.
