ODNR unveils statewide water mapping tools
Mar. 12—COLUMBUS — The Ohio Department of Natural Resources has launched new online tools for water and land-use planning, groundwater management and resource development.
Key tools include:
—Water Withdrawal Facility Locator, online at Shows locations and high-capacity water use data for water withdrawal facilities in Ohio, helping stakeholders address sustainability and plan for future development.
—Aquifer Yield Map, online at Displays groundwater production rates across Ohio, assisting well drillers, homeowners, municipalities and industries in estimating aquifer yields.
—Hydraulic Conductivity Map, online at The first statewide map showing how groundwater moves through Ohio's primary aquifers, aiding in groundwater flow modeling, contamination prediction and irrigation planning.
"The goal with these maps is to deliver a statewide, data-driven assessment of Ohio's aquifer resources in a way that can inform responsible development and guide site-specific investigations," said Craig Nelson, lead hydrogeologist on the mapping project, in a press release.
The Aquifer Yield and Hydraulic Conductivity maps were funded in part by an Ohio Water Development Authority Research & Development Grant.
High-resolution printed maps can be ordered at for $15 each.
