Biogeochemical variability of plants at native and altered sites, San Juan Basin, New Mexico
L. P. Gough, R. C. Severson
1981, Professional Paper 1134-D
The San Juan Basin is becoming a major energy resource region. The anticipated increase in strip mining for coal can be expected to alter the geochemical and biogeochemical environment. because such activities destroy the native vegetation communities, rearrange the rock strata, and disrupt natural soil development. This study investigated the...

Volume 4 of the water resources data for the 1980 water year for California consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality in lakes and reservoirs; and water levels in wells. This report contains discharge records for 199 gaging stations; stage and...
Geophysical reconnaissance of Lemmon Valley, Washoe County, Nevada
Donald H. Schaefer, Douglas K. Maurer
1981, Open-File Report 80-1123
Rapid growth in the Lemmon Valley area, Nevada, during recent years has put increasing importance on knowledge of stored ground water for the valley. Data that would fill voids left by previous studies are depth to bedrock and depth to good-quality water beneath the two playas in the valley. Depths...

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...
