Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Ohio Kentucky Indiana Water Science Center


Welcome to the “new” Ohio-Kentucky-Indiana  Water Science Center. In October 2017, the three Water Science Centers were merged to become one "Integrated" Science Center. We look forward to helping you achieve your goals by providing water quantity and quality information, as well as scientific tools and understanding, when and where they are needed by citizens, businesses, and public officials.
