The Upper Missouri Watershed Alliance has conducted water chemistry and quality studies in the main stem of the upper Missouri river since 2015. The Montana Department of Environmental Quality (MT DEQ) has supported these studies through a grant each year. We are concerned about the significant increase in two important nutrients identified in 2017; nitrogen and phosphorous when compared to the 2016 study. We intend to expand our studies and determine the trend of this increase as well as the potential impact on the river. We are sharing this data with watershed stakeholders and are soliciting their input to address these concerns.
