Water-resources data for the Fort Berthold Indian Reservation, west-central North Dakota
A study of the water resources of the Fort Berthold Indian Reservation was undertaken to characterize the quality and quantity of ground-water and surface-water resources. The purpose of this report is to document the data-collection procedures used during the study and to present the data collected in tabular and graphical form. Ground-water data were collected during May 1990 through November 1992. The data presented in this report include records of 1,325 wells, test holes, and springs; water-levels fcr 40 observation wells; drillers' logs for 211 wells and test holes; gamma-ray and resistivity logs for 21 test holes drilled in June 1992; water-quality data for 293 water samples from wells ani springs; and trace-element data for 225 water samples from wells. Surface-water data were collected on Bear Den Creek, East Fork Shell Creek, Deepwater Creek, Moccasin Creek, and Squaw Creek from April 1990 through September 1992. Initial!}', five miscellaneous measurement sites were established so that discharge data, selected physical properties of water, and water samples for water-quality analysis could be collected. Gravity data were collected over parts of the Fort Berthold Indian Reservation. As part of the gravity survey, positional data were acquired using global positioning satellite technology.
