Preliminary map showing availability of water from glacial-drift aquifers in Towner County, north-central North Dakota

This preliminary map is the first product of the ground-water resources study of Towner County, which has an area of 1,049 mi^2 (2,717 km^2) in north-central North Dakota (see location map).  The study is part of a statewide program to determine the location, extent, chemical quality, and hydrologic characteristics of the ground-water reservoirs (aquifers) in North Dakota.  The study was made by the U.S. Geological Survey in cooperation with the North Dakota State Water Commission, the North Dakota Geological Survey, and the Towner County Water Management District.
