Hydrologic-Information Needs for Oil-Shale Development, Northwestern Colorado

Description: From purpose: The purpose of this report is to summarize existing hydrologic information in the Piceance basin, to describe types of needed information, to suggest methods of obtaining needed information, and to outline standards for collection. The report also will provide guidance for comprehensive integrated hydrologic studies that will be necessary for water-resource planning in oil-shale development. These studies should provide hydrologic understanding that will benefit all aspects of water-resource and oil-shale development in the region.

Digital-Transport Model Study of the Potential Effects of Coal-Resource Development on the Ground-Water System in the Yampa River Basin, Moffat and Routt Counties, Colorado

Description: From abstract: Large increases in coal mining currently (1979) taking place in the Yampa River basin are expected to continue during the 1980's and may adversely impact both the ground-water and surface-water quality in the basin. One potential source of adverse impact is the dissolution of soluble minerals contained in the overburden material disturbed during the mining. This potential impact was investigated using digital ground-water transport-modeling techniques.

Water-Quality Characteristics of Six Small, Semiarid Watersheds in the Green River Coal Region of Colorado

Description: From introduction: This report presents the data collected from six watersheds in northwestern Colorado and describes an initial step in the regionalization of water-quality characteristics and identification of transferability of data from individual, studied watersheds to unstudied watersheds in northwestern Colorado.

A Data-Management System for Areal Interpretive Data for the High Plains in Parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming

Description: 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.

Characteristics of Urban Runoff from Grange Hall Creek at Northglenn, Adams County, Colorado

Description: Purpose: The purpose of the study was to (1) determine quantity and quality of urban runoff from the upper Grange Hall Creek drainage basin in Northglenn; (2) identify constituents exceeding water-quality standards for agricultural waters; (3) compare differences in quality between dry-weather flow, snowmelt runoff and rainfall runoff; (4) determine rainfall-runoff relationships; (5) investigate relationships between constituent concentrations, specific conductance, and streamflow; and (6) suggest, where appropriate, alternatives of urban-runoff management.

National Uranium Resource Evaluation: Lamar Quadrangle, Colorado and Kansas

Description: Abstract: Uranium resources of the Lamar Quadrangle, Colorado and Kansas, were evaluated using National Uranium Resource Evaluation criteria. The environment favorable for uranium is the Lower Cretaceous Dakota Sandstone in the area east of John Martin Reservoir for south Texas roll-type sandstone deposits. Carbonaceous trash and sulfides are abundant in the Dakota Sandstone. The unit underlies a thick Upper Cretaceous section that contains bentonitic beds and uraniferous marine black shale. Water samples from the Dakota Sandstone aquifer contain as much as 122 parts per billion Uranium-3 Oxygen-8. Geologic units considered unfavorable include most of the Paleozoic rocks, except in the Brandon Fault area; the Upper Cretaceous rocks; and the Ogallala Formation. The Dockum Group, Morrison Formation, and Lytle Member of the Purgatoire Formation are unevaluated because of lack of data.

Aztec Quadrangle, New Mexico and Colorado

Description: From purpose and scope: The purpose of the National Uranium Resource Evaluation (NURE) program of the U.S. Department of Energy (DOE) is to identify and delineate areas and environments within the Aztec 10X20 Quadrangle, New Mexico and Colorado, that exhibit characteristics favorable for the occurrence of uranium deposits that have the potential to contain at least 100 metric tons U3 08 total endowment with a minimum grade of 100 ppm (0.01 percent) U3 08 . Evaluation is based on geochemical, mineralogic, hydrologic, aerial radiometric, sedimentologic, and general geologic characteristics of the formations in the quadrangle.
