Ohio-Kentucky-Indiana Water Science Center


Our Ohio-Kentucky-Indiana WSC priority is to continue the important work of the Department of the Interior and the USGS, while also maintaining the health and safety of our employees and community.  Based on guidance from the White House, the CDC, and state and local authorities, we are shifting our operations to a virtual mode and have minimal staffing within our offices.
