ISWS provides research and data to help better understand and manage water resources statewide. Our reports cover topics such as groundwater levels, water quality, flooding, drought, and climate patterns in Illinois.
These materials support decision-making by scientists, communities, and public agencies. Most reports are freely available online and include both current studies and historical records that reflect more than a century of work in water science and public service.
