The U.S. Geological Survey, through its Water Resources Division, investigates the occurrence, quantity, quality, distribution, and movement of the surface and underground water that composes the Nation's water resources. This publication contains a brief description of the ongoing investigations of the North Dakota District.
Much of the Geological Survey program is conducted in cooperation with several state agencies and other Federal agencies. The publications resulting from the program are listed periodically in a miscellaneous release titled, "Water Resources Investigations in North Dakota, 19xx." The last such release was issued in 1976. They are also listed in a monthly nationwide release titled, "New Publications of the Geological Survey, List xxx--Publications issued in month 19xx."
