Maps showing ground-water conditions in the Monument Valley and northern part of the Black Mesa areas, Navajo, Apache, and Coconino counties, Arizona, 1976
G. W. Levings, C. D. Farrar
1977, Water-Resources Investigations Report 77-44
The Monument Valley and the northern part of the Black Mesa areas include about 2,700 sq mi in northeastern Arizona and are entirely in the Navajo and Hopi Indian Reservations. The main source of water is from the several aquifers that are made up of one or more formations. The...
Heavy metal discharges into Shasta Lake and Keswick reservoirs on the upper Sacramento River, California; a reconnaissance during low flow
D. Kirk Nordstrom, Everett A. Jenne, Robert C. Averett
1977, Water-Resources Investigations Report 76-49
Four out of seventeen streams entering the Shasta-Keswick Reservoir system in California contribute up to 94 percent of the heavy metal load into the upper Sacramento River under the low flow conditions which existed in the fall of 1974. Of these four streams, three contain acid mine drainage, with Spring...

1977, Water-Resources Investigations Report 77-48
Low-flow frequency data for 161 continuous-record gaging stations having eight or more complete years of record are presented for 1-, 7-, 14-, 30-, 60-, 90-, 120-, 183-, and 365-day low flows for frequencies ranging from once in 2 years to once in 100 years. In addition, 8,146 low-flow measurements at...
Water quality of selected streams in the coal area of southeastern Montana
J. R. Knapton, P. W. McKinley
1977, Water-Resources Investigations Report 77-80
This report summarizes and evaluates water-quality data collected at 35 stream sites the the coal region of southeastern Montana. Sarpy Creek, Armells Creek, and Rosebud Creek sometimes have dissolved-solids concentrations that cause water to be marginal for agricultural purposes. At times of rainfall and snowmelt, the runoff water mixes with...

Computer simulation of two-dimensional unsteady flows in estuaries and embayments by the method of characteristics : Basic theory and the formulation of the numerical method
Chintu Lai
1977, Water-Resources Investigations Report 77-85
Two-dimensional unsteady flows of homogeneous density in estuaries and embayments can be described by hyperbolic, quasi-linear partial differential equations involving three dependent and three independent variables. A linear combination of these equations leads to a parametric equation of characteristic form, which consists of two parts: total differentiation along the bicharacteristics...
Ground-water resources of the alluvial aquifers in northeastern Larimer County, Colorado
R. T. Hurr, P.A. Schneider
1977, Water-Resources Investigations Report 77-7
Ground water is a source of municipal, domestic, stock, and irrigation supply for most of northeastern Larimer County, Colo. A study of the alluvial aquifers in the northeastern part of the county was conducted to determine volume of water in storage, rate and location of ground-water withdrawals, and chemical quality...

Hydrologic considerations associated with dredging spring ponds in Wisconsin
William J. Rose
1977, Water-Resources Investigations Report 77-18
Spring ponds (small spring-fed bodies of water) are natural features of some glaciated areas and have a continuous flow of ground water entering through their bottoms and exiting through surface outlets. Dredging has been used to restore ponds that have been filled in part or totally by sediment. The purpose of...
