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.

Low-flow statistics computed for streamflow gages and methods for estimating selected low-flow statistics for ungaged stream locations in Ohio, water years 1975–2020

A study was conducted by the U.S. Geological Survey, in cooperation with the Ohio Water Development Authority and the Ohio Environmental Protection Agency, to compute low-flow frequency, flow-duration, and harmonic mean flow statistics for long-term streamflow gages and to develop regression equations to estimate those statistics at unregulated, ungaged stream locations in Ohio. The flow statistic

Analysis of water use associated with hydraulic fracturing and determination of baseline water quality in watersheds within the shale play of eastern Ohio, 2021–23

The U.S. Geological Survey, in cooperation with the Ohio Department of Natural Resources, performed a two-part study to (1) assess water use and temporal trends and changes in streamflow, and to (2) characterize 2021–23 baseline water quality, as they relate to oil and gas extraction activities in selected eastern Ohio watersheds. Between calendar years 2010 and 2019, hydraulic fracturing water wi

Assessing stormwater reduction through green infrastructure: RecoveryPark (Detroit, Mich.)

The effectiveness of green infrastructure (including urban land conversion and bioswales) at reducing stormwater runoff is being assessed at RecoveryPark, a redeveloped urban farm in Detroit, Michigan. This study will monitor pre- and post-construction storm-sewer flow, groundwater levels, precipitation, and potential evapotranspiration (ET) to evaluate stormwater-volume reduction in response to...

Assessing stormwater reduction using green infrastructure: Gary City Hall (Gary, Ind.)

The effectiveness of green infrastructure (rain gardens and decreased impervious surface) at reducing stormwater runoff and capturing dissolved chloride is being assessed at a redevelopment project at Gary City Hall (Gary, Indiana). This study will evaluate pre- and post-construction hydrologic conditions using data collected by monitoring storm-sewer flow, groundwater levels, soil moisture, and...
