Geohydrology of the Standing Rock Indian Reservation, North and South Dakota

Effective improvement of economic and social conditions of Indians living on the Standing Rock Indian Reservation has been hampered by lack of adequate and reliable information about the quantity and quality of water supplies available for development. Compounding the problem is the recent filling of Oahe Reservoir (now Lake Oahe), which flooded about 55,000 acres of Indian land, and the consequent relocation of many residents. This report summarizes the results of a water-resources study made at the request of the U.S. Bureau of Indian Affairs. It is intended to provide some of the needed information on water supplies that could be used to alleviate the problems mentioned.

Completion and testing of Madison Limestone test well 3, NW1/4SE1/4 sec. 35, T.2N., R.27E., Yellowstone County, Montana

Selected intervals in the lower and upper parts of the Mission Canyon Limestone of Mississippian age, and the Amsden Formation and Tensleep Sandstone of Pennsylvanian age, containing water with dissolved-solids concentrations of 3,000 milligrams per liter or less, were perforated through 7-inch casing that was cemented to the wells of the borehole. Total flow from all perforated intervals after development of each interval by swabbing and flowing was 125 gallons per minute. Total flow increased to 2,900 gallons per minute after acidizing and fracturing each unit through perforations. Radioactive tracer surveys indicate about 65 percent of the flow was from perforations in the upper part of the Mission Canyon Limestone. Based on analysis of data from a step-drawdown test, the values of transmissivity and coefficient of storage considered as most reasonable are 38,000 gallons per day per foot and 0.00002 respectively. Maximum temperature of water, measured at land surface, was 56.6 degrees Celsius. (USGS)

Geohydrology of Crow Creek and Lower Brule Indian Reservations, South Dakota

Effective improvement of economic and social conditions of Indians living on Crow Creek and Lower Brule Reservations has been hampered by lack of adequate and reliable information about the quantity and quality of water supplies available for development. Compounding the problem, and making especially pressing the need for discovery and development of new water supplies, is the recent filling of Fort Randall and Big Bend Reservoirs on the Missouri River, and the consequent relocation of may residents. Much of the best land and known water supplies are inundated beneath the reservoirs. This report summarized the results of a water-resources study made at the request of the U.S. Bureau of Indian Affairs.
