From introduction: This report relates to the first of the above objectives by describing stream quality in the Yampa River basin through 1976, with particular emphasis on conditions from August 1975 through September 1976. The content of this report is, at times, relatively technical. This is intentional. The report is aimed not at planners and decision makers but rather at those persons assigned the task of having to design, implement, and interpret a river basin assessment. The techniques and procedures used to determine ambient stream quality in the Yampa River basin have been presented in detail so that their applicability to other river basins can be determined. For the planner and decision maker, the results presented in this report are summarized in less technical terms in phase-l (Steele and others, 1979) and phase-ll summary reports.

From abstract: During fiscal years 1978 through 1981, the U.S. Geological Survey contracted for the acquisition and analysis of hydrologic data from 104 surface water stations, 26 ground water stations, and 15 precipitation gages as well as for several hundred miscellaneous surface water measurements of flow and water quality. The work was performed in Montana, North Dakota, Wyoming, Utah, New Mexico, and Oklahoma, terminating at the end of the fiscal year 1981. This report is an assessment of this contracting effort from the standpoint of cost and of quality control measures employed to ensure an acceptable product.

Thirty-six color photomicrographs of thin sections of selected rock samples collected for analysis from the Copper Mountain District of central Wyoming.

Abstract: This report is a supplement to the report, "Effect of pumpage on ground-water levels as modeled in Laramie County, Wyoming," published as U.S. Geological Survey Water-Resources Investigations Open-File Report 80-1104 which describes ground-water conditions in post-Cretaceous rocks in Laramie County. The computer program and the data used to model ground-water conditions in post-Cretaceous rocks in Laramie County are listed in this report.

From abstract: The High Plains Regional Aquifer System Analysis study has developed a regional water-resources (and related) data storage and retrieval system to organize and preserve areal interpretive data. The system is general and can easily be adapted for other studies. This report documents the High Plains data base as well as the general system that is independent of the High Plains area.

From abstract: "A digital model was used to simulate ground-water flow within the Bates Creek alluvial aquifer, southwest of Casper, Wyoming. Hydrologic data was collected during 1977 and 1978 were used to develop the flow model under steady-state and transient. Three scenarios for operating the stream-aquifer system were evaluated with the digital model." It contains maps, graphs, and tables.
