Habitat Suitability Index Models: Canvasback (breeding habitat)
Richard L. Schroeder
1984, FWS/OBS 82/10.82
Canvasbacks (Aythya valisineria) breed from Alaska south to Montana and the Dakotas, with the highest breeding densities found in the parklands of Southcentral Canada (Bellrose 1976). Canvasbacks nest over water in a variety of wetland habitats, including large marshes, ponds, sloughs, and potholes. Their preferred breeding habitat is shallow prairie...
Computation and use of volume-weighted-average concentrations to determine long-term variations of selected water-quality constituents in lakes and reservoirs
Frank C. Wells, Terry L. Schertz
1984, Water-Resources Investigations Report 83-4287
A computer program using the Statistical Analysis System has been developed to perform the arithmetic calculations and regression analyses to determine volume-weighted-average concentrations of selected water-quality constituents in lakes and reservoirs. The program has been used in Texas to show decreasing trends in dissolved-solids and total-phosphorus concentrations in Lake Arlington...
Application of a parameter-estimation technique to modeling the regional aquifer underlying the eastern Snake River Plain, Idaho
S. P. Garabedian
1984, Open-File Report 84-461
A nonlinear, least-squares regression technique for the estimation of ground-water flow model parameters was applied to the regional aquifer underlying the eastern Snake River Plain, Idaho. The computer program simulates two-dimensional, steady-state ground-water flow. Hydrologic data for the 1980 water year were used to calculate recharge rates, boundary fluxes, and...
Generalized thickness and configuration of the top of the intermediate aquifer, west-central Florida
Miguel A. Corral Jr., Richard M. Wolansky
1984, Water-Resources Investigations Report 84-4018
Generalized map show the thickness and top of the intermediate aquifer in west-central Florida within the boundaries of the Southwest Florida Water Management District. The intermediate aquifer consists of a series of water-bearing units and confining beds between the surficial aquifer (water table) and the Floridan aquifer. This aquifer contains...
The Nisqually Glacier, Mount Rainier, Washington, 1857-1979: A summary of the long-term observations and a comprehensive bibliography
C. C. Heliker, Aaron H. Johnson, S. M. Hodge
1984, Open-File Report 83-541
Nisqually Glacier on Mount Ranier, Washington has a long record of terminus position observations and ice-surface altitude measurements along specific profiles, and has been the topic of numerous scientific studies. From the earliest observations in 1857 to the present many individuals and several different organizations have been involved in data...
Maps showing selected geology and phosphate resources of the Stewart Flat quadrangle, Caribou County, Idaho
Pamela Dunlap Derkey, Ken Paul, Pamela Palmer, Mahasti Fakourbayat, Nancy J. Wotruba, R. David Hovland
1984, Mineral Investigations Resource Map 72
This report summarizes information on the thickness, grade, lateral continuity, phosphate resources, and ownership of phosplate-bearing units in the Meade Peak Phosphatic Shale Member of the Phosphoria Formation in the Stewart Flat quadrangle. This report is one of a series of quadrangle reports prepared by the Idaho Bureau of Mines...
Water-use computer programs for Florida
L.H. Geiger
1984, Open-File Report 84-442
Using U.S. Geological Survey computer programs L149-L153, this report shows how to process water-use data for the functional water-use categories: public supply, rural supply, industrial self-supplied, irrigation, and thermo-electric power generation. The programs are used to selectively retrieve entries and list them in a format suitable for publication. Instructions are...
