The Division of Geological Survey studies and maps Ohio’s geology, maintains geologic records and samples, collects ground water data, and monitors seismic activity.
Welcome to the temporary website of the Ohio Department of Natural Resources. We are developing a new, dynamic, and user-friendly website that won’t be ready until late summer.
The Division’s temporary website has some of our most popular features available, but not everything that used to be available online. We are working to keep you informed, provide basic information and forms, and offer ways to contact us for more information. Please keep checking our site for news, updates, information, and access to online applications/forms as they become available. Thank you for your patience.
