Habitat Suitability Index Models and Instream Flow Suitability Curves: Pink salmon
Robert F. Raleigh, Patrick C. Nelson
1985, FWS/OBS 82/10.109
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model and instream flow suitability curves for the pink salmon (Oncorhynchus gorbuscha). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0...

Documentation of a numerical code for the simulation of variable density ground-water flow in three dimensions
L.K. Kuiper
1985, Water-Resources Investigations Report 84-4302
A numerical code is documented for the simulation of variable density time dependent groundwater flow in three dimensions. The groundwater density, although variable with distance, is assumed to be constant in time. The Integrated Finite Difference grid elements in the code follow the geologic strata in the modeled area. If...
Hydrogeology of the Cross Bar Ranch well-field area and projected impact of pumping, Pasco County, Florida
C. B. Hutchinson
1985, Water-Resources Investigations Report 85-4001
The hydrogeology and development of a groundwater flow model are described for a 121-square-mile area in Pasco County, Florida. The hydrogeologic framework consists of the surficial aquifer--a thin blanket of sand--and the underlying carbonates of the upper Floridian aquifer. The aquifers are separated by a leaky sand and clay confining...
Water-surface elevations for the high tide of December 15, 1977, in the Puget Sound region, Washington
L. M. Nelson
1985, Water-Resources Investigations Report 84-4293
An unusually high oceanic tide on December 15, 1977, caused flooding of lowlying, nearshore parts of western Washington, including several areas in the Puget Sound region. At Seattle, the December 15 high tide of 14.8 feet above MLLW (mean lower low water datum; 8.55 feet above the National Geodetic Vertical...

Hydrogeology of the southwestern part of the Town of Hempstead, Nassau County, New York
R.K. Krulikas
1985, Water-Resources Investigations Report 85-4288
The groundwater resources of the southwestern part of the Town of Hempstead in Nassau County, NY were investigated in 1984. The area studied encompasses 85 sq mi, or 68% of the town 's 125-sq mi area. The groundwater reservoir underlying the area consists of unconsolidated gravel, sand, silt, and clay...
Evaluation of the Mission, Santee, and Tijuana hydrologic subareas for reclaimed-water use, San Diego County, California
J. A. Izbicki
1985, Water-Resources Investigations Report 85-4032
A study was made to determine the suitability of three small hydrologic subareas in San Diego County, California, for reuse of treated municipal wastewater (reclaimed water). Groundwater quality has been impacted by agricultural water use, changes in natural recharge patterns, seawater intrusion, and groundwater movement from surrounding marine sediments. Groundwater...
Comparison of two methods for estimating ground-water recharge in 1978-80, Santa Maria Valley, California
Paul Lipinski
1985, Water-Resources Investigations Report 85-4129
Infiltration from the Santa Maria River and the lower part of the Sisquoc River constitutes most of the groundwater recharge to the aquifer system of Santa Maria Valley, California. The annual recharge volumes commonly are much greater or smaller than the long-term average annual recharge. A comparison of two methods...
Geology and geochronology of granitoid and metamorphic rocks of late Archean age in northwestern Wisconsin
P.K. Sims, Z. E. Peterman, R. E. Zartman, F. C. Benedict
1985, Professional Paper 1292-C
Granitoid rocks of the Puritan Quartz Monzonite and associated biotite gneiss and amphibolite in northwestern Wisconsin compose the southwestern part of the Puritan batholith of Late Archean age. They differ from rocks in the Michigan segment of the batholith in having been deformed by brittle-ductile deformation and partly recrystallized during...
Time of travel, water quality, and bed-material quality in the Cuyahoga River within the Cuyahoga Valley National Recreation area, Ohio
C.J. Childress
1985, Water-Resources Investigations Report 85-4065
Three studies were conducted in the Cuyahoga Valley National Recreation by the U. S. Geological Survey to (1) establish the relationship between time of travel and discharge through the park reach of the Cuyahoga River, (2) characterize water quality of the Cuyahoga River within the park over a 24-hour period,...

Hydrologic reconnaissance of the Kolob, Alton, and Kaiparowits Plateau coal fields, south-central Utah
Gerald G. Plantz
1985, Hydrologic Atlas 684
The study area in south-central Utah (fig. 1) is noted for its large coal reserves in the Alton, Kolob, and Kaiparowits Plateau coal fields. The area also is noted for its scenic beauty and general scarcity of water. Although there has been very little development of the coal resources through...

Gravity survey and depth to bedrock in Carson Valley, Nevada-California
D. K. Maurer
1985, Water-Resources Investigations Report 84-4202
Gravity data were obtained from 460 stations in Carson Valley, Nevada and California. The data have been interpreted to obtain a map of approximate depth to bedrock for use in a ground-water model of the valley. This map delineates the shape of the alluvium-filled basin and shows that the maximum...
Ground-water resources and potential hydrologic effects of surface coal mining in the northern Powder River basin, southeastern Montana
Steven E. Slagle, Barney D. Lewis, Roger W. Lee
1985, Water Supply Paper 2239
The shallow ground-water system in the northern Powder River Basin consists of Upper Cretaceous to Holocene aquifers overlying the Bearpaw Shale--namely, the Fox Hills Sandstone; Hell Creek, Fort Union, and Wasatch Formations; terrace deposits; and alluvium. Ground-water flow above the Bearpaw Shale can be divided into two general flow patterns....
