Approximate ground-water-level contours, April 1981, for the Soquel-Aptos area, Santa Cruz County, California
Richard M. Bloyd
1981, Open-File Report 81-680
Ground-water levels in selected wells were measured in the Soquel-Aptos, Calif., area in April 1981. On the basis of these measurements approximate ground-water-level contours were constructed. The general direction of ground-water movement in the Soquell-Aptos area is from the ridges in the northern part of the area, toward the adjacent...
Apparent water resistivity, porosity, and ground-water temperature of the Madison limestone and underlying rocks in parts of Montana, Nebraska, North Dakota, South Dakota, and Wyoming
L.M. MacCary
1981, Open-File Report 81-629
The need for large quantities of energy has increased interest in the Fort Union coal region of the Northern Great Plains. Extensive coal development would place a heavy demand on the region's limited streamflow. Some Paleozoic rocks that underlie the Fort Union coal region might supply, at least on a...
Altitude of the water table in the alluvial and other shallow aquifers along the Colorado River near La Grange, Texas, December 1980
Paul Rettman
1981, Open-File Report 81-1063
The water-table contours on this map were constructed from water-level control derived from an inventory of springs and wells in the area, U.S. Geological Survey topographic maps, and from data presented by Rogers (1967). Because of the available water-level control and the rough terrain throughout the area, the delineation of...
Water-resources investigations of the U.S. Geological Survey in Colorado: fiscal year 1981
W.E. Price
1981, Open-File Report 81-150
The report provides an overview of water-resources data collection and hydrologic investigations in Colorado from October 1, 1980, to September 30, 1981. Most of the work is carried out in cooperation with 51 Federal, State, and local agencies. Data are being collected at 503 surface-water gaging stations, 161 surface-water quality...
Water-resources investigations of the U.S. Geological Survey in Arkansas, fiscal year 1981
1981, Open-File Report 81-1003
During fiscal year 1981 there were 20 water-resources investigations in progress by the Arkansas District of the U. S. Geological Survey 's Water Resources Division. Investigations that mainly involved data collection included surface-water gaging, water-level measuring, water-quality sampling, sediment sampling, and water-use inventorying. Interpretive studies included three that were principally...
