Coeur d'Alene Basin Water-Quality Monitoring

Science Center Objects

We partner with the EPA to conduct long-term water-quality and streamflow monitoring and streamflow measurements in the Coeur d’Alene River Basin, which has been widely impacted by historic mining activities. We collect water-quality samples 2-4 times per year at 20 sites throughout the basin. Our scientists analyze these samples for metals, hardness, sediment, and nutrients. In addition, we maintain 12 streamgages in the basin. The data from sampling and monitoring are used to help the EPA target remedial actions, to evaluate the effectiveness of remedial actions, and to describe long-term water-quality and streamflow trends.
