NRRI scientists are involved in projects to understand impacts of human activities, including land cover and climate change, on water quality, flow and temperature in area streams, and invasive species introductions to area water bodies. The goal is to develop management strategies to reduce the impacts of human activities and climate change on sensitive ecosystems. Scientists conduct intensive flow and water quality monitoring to contribute to underlying knowledge about how area streams behave under different conditions, and deliver the data to managers, who then identify appropriate protection strategies to mitigate the impacts of human activities. Other teams use models to quantify flow and temperature so that they can predict the impacts of future climate on those critical parameters.

Results of these efforts will lead to recommendations to help optimize the type and location of management activities such as tree planting, riparian zone restoration, and reduction of impervious surfaces within the watershed. NRRI scientists also are working with businesses to test equipment that will reduce or eliminate the potential introduction of aquatic invasive species to area water bodies.
