Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2017 Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2017
Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring (RIM) stations for the period 1985 through 2017. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called...
Monthly Streamflows, Drought Indices, and Supporting Statistics for USGS Gage Stations Used to Identify Variability of Hydrological Droughts in the Conterminous United States, 1951 through 2014 Monthly Streamflows, Drought Indices, and Supporting Statistics for USGS Gage Stations Used to Identify Variability of Hydrological Droughts in the Conterminous United States, 1951 through 2014
A table is presented listing: (1) monthly streamflows, (2) drought duration dates, (3) drought severity indices, (4) supporting statistics, and (5) identification tags, for analysis of hydrological droughts in the Conterminous United States (CONUS). Data were summarized from USGS streamflow daily values (DV), readily available from the U.S. Geological Survey National Water Information...
Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay Nontidal Network stations: Water years 1985-2016 Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay Nontidal Network stations: Water years 1985-2016
Degassing thermal features at Yellowstone National Park include spectacular geysers, roiling hot springs, bubbling mud pots, fumaroles, frying pans, and areas of passive degassing characterized by steaming ground. Most of these features are readily identified by visible clouds of steam that are occasionally accompanied by a strong rotten egg odor from emissions of hydrogen sulfide gas...
Flood Inundation, Flood Depth, and High-Water Marks Associated with the Flood of July 2016 in Northern Wisconsin and the Bad River Reservation Flood Inundation, Flood Depth, and High-Water Marks Associated with the Flood of July 2016 in Northern Wisconsin and the Bad River Reservation
This data set contains shapefiles and metadata associated with flood inundation maps for three areas of the Bad River, associated with the flood of July 2016 in northern Wisconsin and the Bad River Reservation. The shapefiles are grouped by subarea and include the Bad River (Bad_layers), Beartrap Creek (Beartrap_layers), and Denomie Creek (Denomie_layers). Shapefiles were created for the...
Flood Inundation, Flood Depth, and High-Water Marks for Selected Areas in West Virginia from the June 2016 Flood Flood Inundation, Flood Depth, and High-Water Marks for Selected Areas in West Virginia from the June 2016 Flood
The U.S. Geological Survey (USGS) worked in cooperation with the Federal Emergency Management Agency (FEMA) to document the June, 2016 storm event in West Virginia. Heavy rainfall occurred across central and southern West Virginia in June 2016 as a result of repeated rounds of torrential thunderstorms. The storm caused major flooding and flash flooding, with Kanawha, Fayette, Nicholas...
Site and Groundwater-Quality Sample Data for Abandoned Underground Coal Mine Aquifers in West Virginia, July 13, 1973 through September 7, 2016 Site and Groundwater-Quality Sample Data for Abandoned Underground Coal Mine Aquifers in West Virginia, July 13, 1973 through September 7, 2016
This Data Release is a compilation of existing water-quality data associated with groundwater resources originating from abandoned underground coal mines in West Virginia. Data were compiled from multiple sources for the purpose of understanding the suitability of groundwater from abandoned underground coal mines for public supply, industrial, agricultural, and other uses. This...
Nitrogen, Phosphorus, and Suspended-Sediment Loads and Trends measured at the Chesapeake Bay Nontidal Network Stations: Water Years 1985-2014 Nitrogen, Phosphorus, and Suspended-Sediment Loads and Trends measured at the Chesapeake Bay Nontidal Network Stations: Water Years 1985-2014
Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay Nontidal Network (NTN) stations for the period 1985 through 2014. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS...
Borehole geologic-unit top-surface altitude and aquifer-component test data for the Piney Point aquifer, Virginia from 2009 through 2015 Borehole geologic-unit top-surface altitude and aquifer-component test data for the Piney Point aquifer, Virginia from 2009 through 2015
This USGS data release contains (1) geologic-unit top-surface altitudes in boreholes and (2) aquifer-test time-series water-level drawdowns, recoveries, and supporting data from the Piney Point aquifer in Virginia from 2009 through 2015. Extents, compositions, configurations, and geologic relations of six geologic units that compose the Piney Point aquifer were determined from geologists...

Fish and Benthic Macroinvertebrate Flow-Ecology Regression Summary Statistics for Virginia Fish and Benthic Macroinvertebrate Flow-Ecology Regression Summary Statistics for Virginia
Data provided from the Virginia Department of Environmental Quality (DEQ) including simulated values of 72 hydrologic metrics, or indicators of hydrologic alteration (IHA), 37 fish metrics, and 64 benthic invertebrate metrics were reviewed to assess significant flow-ecology relations that may be developed. Hydrologic alteration was represented by simulation of streamflow record for a pre...
