Map: Short-Term Trend in Flow-Adjusted Total Nitrogen Concentration, 2003-2012

Short Term Trend: Over the past 10 years, 54 percent of the monitoring stations show improving flow-adjusted nitrogen concentrations. Only one site showed degrading nitrogen conditions. Between 2003 and 2012: - 25 out of 46 sites show improving flow-adjusted trends for nitrogen concentrations, - 1 site shows degrading trends, and - 20 sites show small changes that are not statistically significant.
