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.
Annual total phosphorus loads to the Great Lakes
Monthly and annual total phosphorus loads were estimated for water years 2014 through 2018 for 23 streamgaged (gaged) sites on tributaries to the Great Lakes.
USGS Kentucky Drought Condition Monitor
The USGS Ohio-Kentucky-Indiana Water Science Center and Kentucky Agricultural Development Board rely upon several parameters to monitor water-supply-drought conditions.
Current Data
This data was formerly known to most as the "Realtime Data" in table format. Although the format has not changed, we now refer to it as "Current Conditions".
