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. Surface total phosphorus concentrations are decreasing/improving significantly at 36 stations, possibly decreasing at 23 stations, increasing/degrading significantly at 2 stations, and possibly increasing at 6 stations.
