# Ohio-Kentucky-Indiana Water Science Center

**Welcome to the Ohio-Kentucky-Indiana Water Science Center (OKI WSC) webpage! We work closely with our local, state, federal, and tribal partners to provide unbiased and timely water resource information on streamflow, water quality, water-use, and groundwater data to resource managers and the public. Our Center includes the key water resources of the Ohio River, Lake Erie, and Lake Michigan.**
