Illinois State Water Survey

Center for Watershed Science

H. Vernon Knapp, Interim Head

The mission of the Center for Watershed Science (CWS) is to generate historical and spatial scientific data, investigate and understand watershed processes, and to provide state-of-the-art scientific and engineering analyses to policymakers, planners, and resource managers in the State of Illinois and beyond so that they can develop and implement sustainable watershed programs based on the best scientific and engineering analyses possible.

It is the goal of the Illinois State Water Survey to be a recognized expert in the State of Illinois in the field of watershed science with special technical expertise in hydrologic, atmospheric, chemical, and watershed studies including monitoring and data collection; analyses, assessment and research; modeling; reconstruction, rehabilitation and restoration; GIS and data management; and public outreach. Our scientific and technical experts will play significant roles in science-based evaluation of environmentally sound, sustainable, and integrated watershed management plans and practices in the State of Illinois and beyond.
