Delineation of buried glacial drift aquifers
Locating and delineating buried glacial-drift aquifers poses one of the major problems to hydrogeologists working in glacial terrain. To show the vertical and horizontal boundaries of aquifers, most techniques require a multiple set of maps, a fence diagram, or a combination of maps and sections. Calculations of the first two moments, mean and standard deviation, of a discontinuous distribution re

Magnitude and frequency of floods in small drainage basins in North Dakota
This report describes methods for estimating flood-peak discharges having 2- to 50-year recurrence intervals on North Dakota streams draining less than 100 square miles ( 259 square kilometres). For gaged sites, frequency estimates are provided directly. For ungaged sites, flood peaks are estimated from multiple-regression equations using drainage-area size and, in two regions, soil-infiltration i

Geology of Griggs and Steele Counties
Griggs and Steele Counties, located at the eastern edge of the Williston basin, are underlain by 400 to 2,600 feet of Paleozoic and Mesozoic rocks that dip gently to the west. The Cretaceous Greenhorn, Carlile, Niobrara, and Pierre Formations lie directly beneath the glacial drift, and shale of the Pierre Formation is exposed in several places along the Sheyenne River. The Pleistocene Coleharbor F

The National Stream Quality Accounting Network (NASQAN) - Some questions and answers
One of the major new efforts of the U.S. Geological Survey is the National Stream Quality Accounting Network (NASQAN). This circular is intended to answer some of the frequently asked questions concerning concepts used in establishing NASQAN, its purposes, design, value, and future plans.

Test drilling at Soldier Creek, Rosebud Indian Reservation, Todd County, South Dakota
Thirty-six test holes were augered by the U.S. Geological Survey in the vicinity of Sol,,r Creek, Rosebud Indian Reservation, Todd County, South Dakota. Wells prcducing more than S gallons per minute (0.32 litre per second) from the Tertiary deposits are rare. However, as much as 20 feet (6.1 metres) of permeable alluvial deposits were penetrated in several test holes. One test ell was pumped for

Data summary of June-July 1975 floods in eastern North Dakota and northwestern Minnesota
Torrential rains during late June and early July 1975, combined with wet antecedent conditions, caused severe flooding, mainly along the lower reaches of the Sheyenne and Maple Rivers and their tributaries in North Dakota, and in the Buffalo and Wild Rice River basins in Minnesota. The Red River of the North from the Fargo-Moorhead area to the Halstad, Minnesota area was also severely flooded. Bec

The Black Hills-Rapid City flood of June 9-10, 1972: A description of the storm and flood
On June 9, 1972, an almost stationary group of thunderstorms formed over the eastern Black Hills of South Dakota near Rapid City and produced record amounts of rainfall and flood discharges. Nearly 15 inches of rain fell in about 6 hours near Nemo, S. Dak., and more than 10 inches of rain fell over a 60-square-mile area. The resulting floods were the highest ever recorded in South Dakota. At least

A method for estimating magnitude and frequency of floods in South Dakota
A general flood-frequency analysis has provided a method for estimating flood magnitudes and frequencies on South Dakota streams. Related flood data useful in planning and design also are included in the report.Two distinct hydrologic regions are delineated within the State. The divisional boundary for these regions is, in general, the western divide of the James River basin. For each region, the

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
