Program Overview
This is the key state program collecting and generating information on the status of Ohio’s water resources. It supports stream gauging to monitor stream flow and lake levels - low flow, high flow and points in between. It operates a network groundwater observation wells. Historic and current data allow a wide range of private and public water users to reliably plan for and use Ohio’s generally abundant water resources, but also react to droughts.
The Water Inventory Program continually compiles and stores precipitation, water storage, and streamflow data. Staff hydrologists are responsible for monitoring ground water levels in Ohio and compiling other hydrologic data. A network of 139 observation wells plus many "Special Project" wells are continually monitored and reported on each month. The "Monthly Water Inventory Report for Ohio" summarizes rainfall, trends in ground water, streamflow, and surface water storage in Ohio as well as evaluating the current overall water supply situation. This is a free publication. To learn more about the observation well network, ask for a copy of the fact sheet "Ground Water Level Monitoring in Ohio"
Environmental, Economic and Public Importance
This program assists nearly every local, state, and federal agency charged with assuring a reliable supply of water for residents and businesses. Moreover, stream data is critical for flood planning and mitigation and for cost- effectively sizing infrastructure like bridges and culverts. Because Ohio generally has abundant supplies of water the program helps the economy by assisting businesses and communities to effectively take advantage of those supplies without overusing them or harming other users of a stream or aquifer. Individuals can also use program data to understand impacts of large water users on local resources. Environmentally, the program helps ensure there are adequate supplies for stream flow, wildlife habitat and recreation. The program helps communities and businesses with water conservation and efficiency efforts which reduces operating costs and maintain supplies for economic and environmental development.
Program Accomplishments
- Maintenance of 139 observation wells through 600 site visits in 61 counties; plans to update decades-old measurement equipment at most wells
