Long-term trends were computed by state partners using the Seasonal Kendall non-parametric technique for annual data collected from 1999-2013. Highly significant trends are indicated with triangles and possible trends are show with colored circles. Bottom total nitrogen concentrations are decreasing/improving significantly at 31 stations, possibly decreasing at 15 stations, and increasing/degrading significantly at 1 station.
