Water-quality data were collected during 1979-87 at selected locations In the central part of the James River basin, North and South Dakota, by the U.S. Geological Survey and the U.S. Bureau of Reclamation to document baseline conditions In three wildlife refuges. These data are needed to determine potential impacts on water quality of augmented flows in the James River from proposed...

Wetlands occur in geologic and hydrologic settings that enhance the accumulation or retention of water. Regional slope, local relief, and permeability of the land surface are major controls on the formation of wetlands by surface-water sources. However, these landscape features also have significant control over groundwater flow systems, which commonly play a role in the formation of...

Ground water is one of the most important natural resources of the United States and degradation of its quality could have a major effect on the welfare of the Nation. Currently (1985), ground water is the source of drinking water for 53 percent of the Nation's population and for more than 97 percent of its rural population. It is the source of about 40 percent of the Nation's public...

Effective management of ground-water resources requires knowledge of all components of the water budget for the aquifer of interest. Efforts to simulate ground-water flow prior to development and the effects of proposed pumping in several of North Dakota's shallow glacial aquifers have been hindered by the lack of reliable estimates of ground-water recharge. This study was done to (1)...

As part of the Souris River water-quality assessment, traveltime, longitudinal-dispersion, and reaeration measurements were made during September 1983 on segments of the 186-mile reach of the Sour is River from Lake Darling Dam to the J. Clark Salyer National Wildlife Refuge. The primary objective was to determine traveltime, longitudinal-dispersion, and reaeration coefficients during...

This report contains summary information on ground-water quality in one of the 50 States, Puerto Rico, the Virgin Islands, or the Trust Territories of the Pacific Islands, Saipan, Guam, and American Samoa. The material is extracted from the manuscript of the 1986 National Water Summary, and with the exception of the illustrations, which will be reproduced in multi-color in the 1986...

The relation of hydrologic setting and temporal variability in hydrology to nutrient content and geochemical characteristics of a group of prairie wetlands and adjacent ground water was studied during the period 1979-82. Although data were collected from many wetlands and wells at the study site, emphasis in this report primarily is on four wetlands two seasonal and two semipermanent and...

Data collected at four meteorologic stations located in west-central North Dakota are presented. In the West Branch Antelope Creek area, meteorologic data were collected at one weather station and two supplemental precipitation stations. The data for West Branch Antelope Creek weather station include: Accumulated precipitation, air temperature, relative humidity, soil temperature, solar...
