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 phosphorus concentrations are decreasing/improving significantly at 27 stations, possibly decreasing at 13 stations, increasing/degrading significantly at 12 stations, and possibly increasing at 10 stations.
