Field conditions at the Maricopa Agricultural Center, Maricopa County, Arizona, June 13, 1988
Sandra J. Owen-Joyce
1988, Open-File Report 88-708
Field conditions were documented during the Landsat satellite overpass of the Maricopa Agricultural Center, Maricopa County, Arizona, on June 13, 1988. Crop types were mapped and photographed for each demonstration farm field. Field conditions described include irrigation, cultivation, and orientation of rows. Field and photographic descriptions are presented in tabular...
Waterfowl Management Handbook
1988, Fish and Wildlife Leaflet 13
The North American Waterfowl Management Plan, the Service's most recent mandate for management of migratory waterfowl, and recent legislation such as the Farm Bill all underscore the need for a single source of information about the management of waterfowl and their habitat. Much of this information exists in scientific papers,...
Preliminary evaluation of the hydrogeologic system in Owens Valley, California
W.R. Danskin
1988, Water-Resources Investigations Report 88-4003
A preliminary, two-layer, steady-state, groundwater flow model was used to evaluate present data and hydrologic concepts of Owens Valley, California. Simulations of the groundwater system indicate that areas where water levels are most affected by changes in recharge and discharge are near toes of alluvial fans and along the edge...
Relation of trihalomethane-formation potential to water-quality and physical characteristics of small water-supply lakes, eastern Kansas
L. M. Pope, J. A. Arruda, C. H. Fromm
1988, Water-Resources Investigations Report 88-4161
The formation of carcinogenic trihalomethanes during the treatment of public surface water supplies has become a potentially serious problem. The U. S. Geological Survey, in cooperation with the Kansas Department of Health and Environment , investigated the potential for trihalomethane formation in water from 15 small, public water supply lakes...
Occurrence and distribution of nitrate and herbicides in the Iowa River alluvial aquifer, Iowa: May 1984 to November 1985
M.G. Detroy, R.L. Kuzniar
1988, Water-Resources Investigations Report 88-4117
From May 1984 to November 1985, the U.S. Geological Survey, in cooperation with the University of Iowa Hygienic Laboratory and the Iowa Department of Natural Resources, Geological Survey Bureau, investigated nitrate and herbicides in the Iowa River alluvial aquifer. The occurrence and distribution of nitrate and selected herbicides were determined...
Habitat Suitability Index Models: American eider (breeding)
A. K. Blumton, Ray B. Owen Jr., William B. Krohn
1988, FWS/OBS 82/10.149
INTRODUCTION The common eider (Somateria mollissima) consists of five subspecies; four are found in North America (Palmer 1976). Six management populations of common eiders have recently been defined in eastern Canada and the United States (Reed and Erskine 1986). The American edier (S. mollissima dresseri), of which three populations are recognized...
Geochemical sampling in arid environments by the U.S. Geological Survey
Margaret Hinkle
1988, Circular 997
The U.S. Geological Survey (USGS) is responsible for the geochemical evaluations used for mineral resource assessments of large tracts of public lands in the Western United States. Many of these lands are administered by the Bureau of Land Management (BLM) and are studied to determine their suitability or nonsuitability for...
Nomenclature of regional hydrogeologic units of the Southeastern Coastal Plain aquifer system
J. A. Miller, R.A. Renken
1988, Water-Resources Investigations Report 87-4202
Clastic sediments of the Southeastern Coastal Plain aquifer system can be divided into four regional aquifers separated by three regional confining units. The four regional aquifers have been named for major rivers that cut across their outcrop areas and expose the aquifer materials. From youngest to oldest, the aquifers are...
Habitat Suitability Index Models: Black-bellied whistling-duck (breeding)
Paul M. McKenzie, Phillip J. Zwank
1988, FWS/OBS 82/10.150
A review and synthesis of existing information were used to develop a model for evaluating the quality of habitat for breeding black-bellied whistling-ducks. The model is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimal habitat). Habitat suitability index models are designed to be used with Habitat...
Water resources data for Florida, water year 1987. Volume 2B. South Florida ground water
W.J. Haire, R.S. Sonenshein, C. Lietz, E. Workman
1988, Water Data Report FL-87-2B
Water resources data for the 1987 water year in Florida consists of continuous or daily discharge for 320 streams, periodic discharge for 38 streams, miscellaneous discharge for 29 streams, continuous or daily stage for 94 streams, periodic stage for 48 streams, peak discharge for 76 streams and peak stage for...
