Reconnaissance investigation of water quality, bottom sediment, and biota associated with irrigation drainage in and near Stillwater Wildlife Management Area, Churchill County, Nevada, 1986-87
R.J. Hoffman, R.J. Hallock, T.G. Rowe, M.S. Lico, H.L. Burge, S.P. Thompson
1990, Water-Resources Investigations Report 89-4105
A reconnaissance was initiated in 1986 to determine whether the quality of irrigation-drainage water in and near the Stillwater Wildlife Management Area, Nevada, has caused or has potential to cause harmful effects on human health, fish, wildlife, or other beneficial uses of water. Samples of surface and groundwater, bottom sediment,...
Delineation of flooding within the Ozark National Scenic Riverways in southeastern Missouri - Round Spring and Powder Mill
Terry W. Alexander
1990, Hydrologic Atlas 712-B
This is the second report in a series of U.S. Geological Survey Hydrologic Investigations Atlases to further supplement the National Park Service general management and development concept plan for the Ozark National Scenic Riverways (National Park Service, 1981) in southeastern Missouri (fig. 1). The technical basis on which the National...
Hydrology, aquatic macrophytes, and water quality of Black Earth Creek and its tributaries, Dane County, Wisconsin, 1985-86
S. J. Field, D.J. Graczyk
1990, Water-Resources Investigations Report 89-4089
An intensive data-collection program for the Black Earth Creek basin in southern Wisconsin was conducted from October 1984 through September 1986 to assess the hydrology, aquatic macrophytes, and water quality in Black Earth Creek by the U.S. Geological Survey, in cooperation with the Wisconsin Department of Natural Resources. Three sites...
Flood frequency of the Savannah River at Augusta, Georgia
C.L. Sanders Jr., H.E. Kubik, J.T. Hoke Jr., W.H. Kirby
1990, Water-Resources Investigations Report 90-4024
To fill an increasing need for reliable information on floods of various recurrence intervals on the Savannah River a flood-frequency relation was developed for the long-term gaging station at Augusta, Georgia. The flood-frequency analysis was complicated by the fact that the Savannah River upstream of Augusta has experienced increasing regulation...
Quaternary geologic map of the Vicksburg 4° x 6° quadrangle, United States
W. A. Gilliland, K. V. Luza, D. E. Pope, E. G. Wermund, R. A. Miller, W. V. Bush, K. N. Jensen, W. D. Fishman, David S. Fullerton, David L. Weide, Charles A. Bush
Gerald Martin Richmond, editor(s)
1990, IMAP 1420(NI-15)
This map is part of the Quaternary Geologic Atlas of the United States (I-1420). It was first published as a printed edition in 1990. The geologic data have now been captured digitally and are presented here along with images of the printed map sheet and component parts as PDF files....
Solid-precipitation (snowfall) measurement intercomparison, Bismarck, North Dakota
Douglas G. Emerson, Kathleen M. Macek-Rowland
1990, Open-File Report 90-124
Difficulties involved in obtaining accurate measurements of solid precipitation (snowfall) have been recognized for many years. Many studies have been conducted to evaluate the accuracy and performance of precipitation gages. These studies show that the type of collection method used can significantly affect the quantity of precipitation measured. Although the...
Water resources data, Florida, water year 1990: Volume 4: Northwest Florida
P.E. Meadows, J.B. Martin, P.R. Mixson
1990, Water Data Report FL-90-4
Water resources data for the 1990 water year in Florida consists of continuous or daily discharge for 349 streams, periodic discharge for 40 streams, miscellaneous discharge for 75 streams, continuous or daily stage for 105 streams, periodic stage for 25 streams, peak discharge for 41 streams, continuous daily tide stage...
A Mass-balance nitrate model for predicting the effects of land use on ground-water quality in municipal wellhead-protection areas
M. H. Frimpter, J.J. Donohue, M.V. Rapacz, H.G. Beye
1990, Open-File Report 88-493
A mass-balance accounting model can be used to guide the management of septic systems and fertilizers to control the degradation of groundwater quality in zones of an aquifer that contributes water to public supply wells. The nitrate nitrogen concentration of the mixture in the well can be predicted for steady-state...
Geohydrology and ground-water quality at the Pueblo Depot activity landfill near Pueblo, Colorado
Kenneth R. Watts, Roderick F. Ortiz
1990, Water-Resources Investigations Report 89-4143
Groundwater samples were collected from the shallow unconfined aquifer at the Pueblo Depot Activity (Colorado) landfill and downstream from the landfill. The Pueblo Depot Activity is a U.S. Department of the Army facility in southeastern Colorado about 15 miles east of Pueblo, Colorado. The land-fill is underlain by upland alluvial...
