Chemical, geologic, and hydrologic data from the study of acidic contamination in the Miami Wash-Pinal Creek area, Arizona, water years 1984-87
J.H. Eychaner, M.R. Rehmann, J. G. Brown
1989, Open-File Report 89-410
Occurrence and movement of acidic contamination in the aquifer and streams of the Pinal Creek basin near Globe, Arizona, is the focus of an ongoing study by the U.S. Geological Survey. Groundwater data from that study for water years 1984 to 1987 include location, construction information, and site plans for...
Test wells SF-1A, 1B, 1C, and SF-2A, 2B, 2C, Santa Fe County, New Mexico
D.L. Hart
1989, Open-File Report 89-37
Two well nests, SF-1 and SF-2, were drilled in Santa Fe County, New Mexico, to monitor the hydraulic head within selected zones of the aquifer. Each well nest consists of three piezometers of shallow, middle, and deep completion within the aquifer. Each set of wells was drilled to a depth...
Functional requirements of computer systems for the U.S. Geological Survey, Water Resources Division, 1988-97
R.M. Hathaway, J.M. McNellis
1989, Open-File Report 89-274
Investigating the occurrence, quantity, quality, distribution, and movement of the Nation 's water resources is the principal mission of the U.S. Geological Survey 's Water Resources Division. Reports of these investigations are published and available to the public. To accomplish this mission, the Division requires substantial computer technology to process,...
Field conditions at the Maricopa Agricultural Center, Pinal County, Arizona, June 16, 1989
Sandra J. Owen-Joyce
1989, Open-File Report 89-392
Field conditions were documented during the SPOT satellite overpass of the Maricopa Agricultural Center, Pinal County, Arizona, on June 16, 1989. Crop types were mapped and photographed for each demonstration farm field, and irrigation, cultivation, and orientation of rows are described. Field and photographic descriptions are presented in tabular and...
Water resources data, Michigan, water year 1988
S. P. Blumer, J.C. Failing, W.W. Larson, C.R. Whited, R.L. LeuVoy
1989, Water Data Report MI-88-1
Water resources data for the 1988 water year for Michigan consists of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water temperature of ground water. This report contains discharge records for 138 streamflow-gaging stations; stage only records for...
Hydraulic data for shallow open-channel flow in a high-gradient flume with large bed material
Fred J. Watts
1989, Water-Resources Investigations Report 89-4001
Hydraulic data for shallow open-channel flow in a high-gradient flume with large bed material are reported. The bed surface consists of natural rock having particle-size range of 0.15 to 0.75 ft. Two different bed-surface configuration (roughness) were tested. The bed material was stable for all discharges. The flume wall was...
Cost-effectiveness of the streamflow-gaging program in Minnesota
T. A. Winterstein, A.D. Arntson
1989, Water-Resources Investigations Report 88-4129
A three-step analysis of the cost-effectiveness of the streamflow-gaging program in Minnesota is documented in this report. In the first step of the analysis, the data uses and funding sources were identified for the 96 continuous-record streamflow-gaging stations operated in 1985. Nineteen sources of funding and 42 uses were identified for...
Applicability of ambient toxicity testing to national or regional water-quality assessment
J. F. Elder
1989, Open-File Report 89-55
Comprehensive assessment of the quality of natural waters requires a multifaceted approach. Based on experimentation designed to monitor responses of organisms to environmental stresses, toxicity testing may have diverse purposes in water quality assessments. These purposes may include identification that warrant further study because of poor water quality or unusual...
Potamocorbula amurensis discovered in San Francisco Bay
Laurence E. Schemel
1989, Interagency Ecological Program Newsletter (1) 3-3
The small Asian clam, Potamocorbula amurensis, is now a major component of benthic communities in most areas of northern San Francisco Bay and some areas of South Bay. Because of its wide tolerance of salinity and other environmental variables and its high abundance in many areas, benthic ecologists believe this...
