Water-quality assessment of Cache Creek, Yolo, Lake, and Colusa counties, California
Stephen K. Sorenson, Ann L. Elliott
1981, Open-File Report 81-677
Cache Creek and its tributaries from Clear Lake to Yolo Bypass have been the subject of quality and quantity of water studies by several governmental agencies since the early 1900's. Water-quality data from these studies showed that water in the basin is of good quality for most of the beneficial...
Changes in the discharge characteristics of thermal springs and fumaroles in the Long Valley Caldera, California, resulting from earthquakes on May 25-27, 1980

1981, Open-File Report 81-203
Changes in flow rate and turbidity have been observed and measured in hot springs in the Long Valley caldera, California, following earthquakes with magnitudes up to 6.3 in May 1980. Increases in flow rate of some hot springs occurred within minutes of the earthquakes, followed by more gradual decreases in...

1981, Open-File Report 81-1014
Southwestern Oregon has several hundred million tons of good-quality minable coal. Because of the dip of the coal beds, the only economical method of mining would be by underground methods. In addition, minor occurrences of low-quality coal have been noted at more than 20 sites in both western and northeastern...

The U.S. Geological Survey is studying the water quality of streams within the Eastern Coal Province. This report contains streamflow, water-quality, and biologic data collected in the North Branch Potomac River basin and in the Maryland portion of the Youghiogheny and Casselman River basins. Data collected from 64 streams from...
Flow characteristics and water-quality conditions in the Spokane River, Coeur D'Alene Lake to Post Falls Dam, northern Idaho
H.R. Seitz, M.L. Jones
1981, Open-File Report 82-102
The Spokane River leaves the northern end of Coeur d'Alene Lake, flows westward past the cities of Coeur d'Alene and Post Falls, Idaho, through the Spokane Valley, and joins the Columbia River west of Spokane, Wash. Cross-sectional properties and water-quality characteristics were determined for flows of 6,100 to 8,440 cubic...
