The digital coverage of the glacial drift aquifers was initially derived from "Map Showing Glacial Drift Aquifers in North Dakota and Estimated Potential Yields, 1986" and modified reflecting new data collected over the last 20+ years. It is primarily the estimated boundaries of the major glacial-drift aquifers initially described in the county ground-water studies produced by the US Geological Survey in cooperation with the North Dakota State Water Commission and the North Dakota Geological Survey. New updates were developed by the Appropriations division staff of the North Dakota State Water Commission. These aquifers are considered to have the greatest potential for yielding significant quantities of water for municipal, industrial, and agricultural purposes. They underlie an area of about 8,900 square miles. It is estimated that about 66 million acre-feet of water is stored in these aquifers. As a comparison, Lake Sakakawea behind Garrison Dam contains approximately 24 million acre-feet of water when full.
