The Task Force and volunteers monitor nitrate levels four times a year through our Community Water Quality Monitoring Program. In addition, we monitor total nitrogen and total phosphorus once a year during the growing season sampling event.

Our program includes 21 sites in the Upper Gallatin River Watershed. These sites capture the influence that geology and land use may have on our river system. We monitor all our sites quarterly to track changes in water quality across hydrological regimes, such as high flow versus low flow, and biological regimes, such as the growing season versus the dormant season.
