About CGAs

County Geologic Atlases (CGAs) are prepared jointly by the Minnesota Geological Survey (MGS) and the Minnesota Department of Natural Resources (DNR). Part A of each county atlas is completed by the MGS and provides a detailed account of geologic materials in the county. Part B of each county atlas is completed by the Minnesota DNR and shows groundwater and hydrology information.

The CGA provides information essential to sustainable management of groundwater resources for applications such as monitoring, water allocation, permitting, remediation, and well construction. The maps and GIS data define aquifer properties and boundaries, as well as the connection of aquifers to the land surface and to the surface-water resources. It also provides a broad range of information on county geology, mineral resources (including construction materials), and natural history.

For information about the CGA program in general, check out the CGA Quick Start Guide. A detailed overview of the program is provided in the Geologic Atlas User's Guide. You can also learn more about CGAs and a list of other published counties on our County Geologic Atlas (CGA) website.
