Mineral resource areas of the Yellowstone River Basin, Montana and Wyoming These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Mineral resource areas are defined as those areas with a high likelihood of containing occurrences of valuable mineral deposits. A variety of sources of minerals information were consulted in compiling a digital map of mineral resource areas for metallic minerals in the Yellowstone River Basin. Source scales varied, but were no smaller than 1:500,000. The data are intended for river-basin level assessment and general analysis and...

Selected Discharge Measurements at Stream-Gaging Stations on Lower Platte River near Ashland, Duncan, Leshara, Louisville, and North Bend, Nebraska, 1934-2006 These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. The accompanying "Lower_Platte_GAGES5" data release consists of two parts, a spatial data layer composed of a vector point data set representing five USGS streamflow gaging stations, and a relational tabular database. The relational database is populated with an inventory and summary of selected river discharge measurements along with a table of measurement details for each selected discharge measurement. The spatial data layer was... Tags: Ashland, Discharge measurement, Duncan, Leshara, Louisville, All tags...
Drainage-area boundaries for selected sampling stations, scale 1:100,000, Yellowstone River Basin, Montana, North Dakota, and Wyoming These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. As part of the U.S. Geological Survey's National Water-Quality Assessment Program, an investigation of the Yellowstone River Basin study unit is being conducted to document status and trends in surface- and ground-water quality. Surface-water samples are collected from streams (or lakes) at specific sampling stations. Water-quality characteristics at each station are influenced by the natural and cultural characteristics of the drainage...

Digital Hydrologic Cataloging-Unit Boundaries for the Powder River, Wyoming, at 1:24,000 Scale These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This data set contains hydrologic cataloging-unit boundaries for selected units within the Powder River drainage basin of Wyoming. The hydrologic unit boundaries were delineated by using a hydrologically-conditioned digital elevation model covering the Powder River drainage basin to produce preliminary boundaries of smaller hydrologic units. Interactive editing followed in which the cataloging-unit boundaries were digitized on computer...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
