Recommended methods for range-wide monitoring of prairie dogs in the United States [ More info] One of the greatest challenges for conserving grassland, prairie scrub, and shrub-steppe ecosystems is maintaining prairie dog populations across the landscape. Of the four species of prairie dogs found in the United States, the Utah prairie dog (Cynomys
Changes in water levels and storage in the High Plains Aquifer, predevelopment to 2009 [ More info] Summarizes graphically the areas where water levels have dropped, and by how much, in this extensive underground water reservoir that covers several states in the mid-continent.
Annual peak streamflow and ancillary data for small watersheds in central and western Texas [ More info] Estimates of annual peak-streamflow frequency are needed for flood-plain management, assessment of flood risk, and design of structures, such as roads, bridges, culverts, dams, and levees.
Land-cover change research at the U.S. Geological Survey-assessing our nation's dynamic land surface [ More info] Estimates of change in major types of land use and land cover from 1973 to 2000 should help model potential future change as climate, population, public policy, and technology change.
Regional assessments of the Nation's water quality--Improved understanding of stream nutrient sources through enhanced modeling capabilities [ More info] Studies of the sources, transport, and fate of nutrients in the streams of six major regions of the conterminous United States.
USGS Hydro-Climatic Data Network 2009 (HCDN?2009) [ More info] This updated subset of USGS streamgages for which the streamflow primarily reflects prevailing meteorological conditions for specified years, screened to exclude sites where human activity affects the natural flow of the watercourse.
Assessment of remaining recoverable oil in selected major oil fields of the Permian Basin, Texas and New Mexico [ More info] The mean total volume of potential additional oil resources that might be added using improved oil-recovery technologies was estimated to be about 2.7 billion barrels of oil.
Streamflow of 2010--Water year summary [ More info] A broad survey of regional patterns in stream flow nationwide. Maps and graphs summarizing streamflow conditions for water-year 2010 (October 1, 2009 to September 30, 2010) in the context of the 81-year period 1930-2010.
Sound data management as a foundation for natural resources management and science [ More info] Arguments in favor of using formal database technology, expecially geodatabases, to manage scientific information, with examples from Texas.
Water quality studied in areas of unconventional oil and gas development, including areas where hydraulic fracturing techniques are used, in the United States [ More info] Maps showing number of water quality samples in areas underlain by unconventional oil and gas resources, broken out by surface water and groundwater.
