Statistical models for estimating flow characteristics of Michigan streams
D. J. Holtschlag, H.M. Croskey
1984, Water-Resources Investigations Report 84-4207
Multiple-regression equations were developed to estimate flow characteristics at ungaged sites. Several readily measureable basin characteristics and an areal adjustment factor are required in the equations. Equations have been prepared to estimate mean and mean monthly flow, flow duration, low flow, peak flow, and flood volume. The precision of the...

D. L. Kresch, Antonius Laenen
1984, Water-Resources Investigations Report 83-4197
Failure of the debris dam, blocking the outflow of Spirit Lake near Mount St. Helens, could result in a mudflow down the Toutle and Cowlitz Rivers into the Columbia River. Flood elevations at the Trojan Nuclear Power Plant on the Columbia River, 5 mi upstream from the Cowlitz River, were...
Steady-state computer model of the water-table aquifer in the Mullica River basin, the Pine Barrens, New Jersey

1984, Water-Resources Investigations Report 84-4295
A two-dimensional steady-state model of the water-table aquifer of the Mullica River basin was made to evaluate the flow system and data required to simulate it. The Mullica River basin covers 570 sq mi and is drained by numerous shallow streams. The water-table aquifer consists of sand and gravel intermixed...

Selenium concentrations in waters tributary to and in the vicinity of the Kesterson National Wildlife Refuge, Fresno and Merced counties, California
T. S. Presser, Ivan Barnes
1984, Water-Resources Investigations Report 84-4122
Analyses were made for selenium in waters and other materials of the Kesterson National Wildlife Refuge. Analyses were also made of source agricultural drainage waters from the San Luis Drain discharged into the refuge, and surrounding irrigation supply and return waters. Selenium concentrations range from 140 to 1 ,400 micrograms...
Ground-water resources of the Mattapoisett River aquifer, Plymouth County, Massachusetts: Summary for water-resource managers
Virginia De Lima, Julio C. Olimpio
1984, Water-Resources Investigations Report 84-4023
Proposed increases in municipal pumpage in the Mattapoisett River valley will triple ground-water withdrawals in the next two decades. Because of State and local concern about the long-term effects of these withdrawals on ground-water levels and streamflow, a digital ground-water-flow model was developed to assist water-resource management. Ten development scenarios...

Ground-water resources of the Mattapoisett River Valley, Plymouth County, Massachusetts
J.C. Olimpio, Virginia De Lima
1984, Water-Resources Investigations Report 84-4043
Ground-water withdrawals by municipal wells in the Mettapoisett River valley, Massachusetts, are expected to triple in the next two decades. State and local concern about the long-term impacts of these withdrawals on ground-water levels and streamflow made it necessary to assess the ground-water resources of the valley and to develop...
Water-quality data for aquifers in east-central New Jersey, 1981-82
D.A. Harriman, L. M. Voronin
1984, Open-File Report 84-821
Data are presented in tables for 238 wells representing nine aquifers underlying the New Jersey Coastal Plain. Approximately two-thirds of these wells are screened in the unconfined Kirkwood-Cohansey aquifer system, the principal source of groundwater in the study area. In addition, seven local streams were sampled in their headwaters under...

Water-level and water-quality changes in Great Salt Lake, Utah, 1847-1983
Ted Arnow
1984, Circular 913
The surface level of Great Salt Lake, Utah, fluctuates continuously, primarily in response to climatic factors. During 1847-1982 the lake surface fluctuated between a low of about 4,191 feet and a high of about 4,212 feet above sea level but showed no net change. From September 18, 1982, to June...
