Overview
The primary goal of the IFA's Regional Water Study - Water Demand and Availability in the Ohio River and Southeast Indiana Region, is to improve the understanding of estimated future groundwater and surface water demand and availability within the public water utility sector so that a gap analysis can be conducted. The questions the study is looking to answer include: How much water is currently available? Will there be enough water to meet the 50-year Public Water Supply needs?
The Study examined the 50-year demand and supply availability in southeastern and southern Indiana watersheds, which are primarily located in Clark, Crawford, Dearborn, Fayette, Floyd, Franklin, Gibson, Harrison, Jefferson, Ohio, Orange, Perry, Posey, Ripley, Scott, Spencer, Switzerland, Union, Vanderburgh, Warrick, Washington, and Wayne counties.
