Electrical Resistivity Tomography (ERT) and Horizontal-to-Vertical Spectral Ratio (HVSR) Data Collected Within and Near Ellsworth Air Force Base, South Dakota, from 2014 to 2019
This data release contains geophysical data from electrical resistivity tomography (ERT) and passive seismic surveys within and near Ellsworth Air Force Base, South Dakota, collected June 2014?September 2019. The data accompanies a USGS scientific invesgations map from Medler and Anderson (2021; LINK HERE) and a USGS scientific investigations report by Bender and others (2021; LINK HERE). The U.S
Historical and Stochastically Generated Climate and Streamflow Data for the Souris River Basin, United States and Canada
The North Dakota State Water Commission and International Joint Commission partnered with USGS to characterize the climate and streamflow in the Souris River Basin and develop a set of daily streamflow traces from 10-day stochastic streamflow traces discussed in Kolars and others (2016).The Kolars and others (2016) dataset is provided and was used to determine the statistical characteristics of hi
Bathymetric Data Collection for Larimore Dam in North Dakota, August 2020
Data were collected in August, 2020 to support development of a bathymetric map for Larimore Dam in Grand Forks County, North Dakota. Global Navigation Satellite System (GNSS) surveying equipment was used in static and real-time kinematic (RTK) mode to establish a local reference mark and check-in/check-out point, to collect water surface elevations, and to collect topographic points along establi
Attributions for nonstationary peak streamflow records across the conterminous United States, 1941-2015 and 1966-2015
The U.S. Geological Survey Dakota Water Science Center, in cooperation with the Federal Highway Administration, analyzed annual peak-flow data to determine if trends are present and provide attribution of trends where possible. Work for the national trend attributions for nonstationary annual peak-flow records was broken into seven regions that are loosely based off of two-digit hydrologic unit wa
Streamflow Observation Points in the Upper Plains, 1973-2018
This produced dataset includes spatially aggregated records of measurements and observations from public and private organizations across the Upper Missouri River Basin. For this dataset the Upper Missouri River Basin is defined as Hydrologic Unit Code 1002-1013, and includes the states of Montana, Wyoming, Utah, North Dakota, and South Dakota. Streamflow measurements are an essential part of unde
Soil-Water Balance model for alluvial deposits in Summerset, South Dakota
A Soil-Water Balance (SWB) model of the alluvial aquifer in north Summerset, South Dakota, was constructed to estimate recharge and potential evapotranspiration volumes and rates for 2017-19. The model area included the northern part of the city of Summerset in west South Dakota along the east range of the Black Hills. The model area was defined as a rectangular area that included the watershed bo
Water-quality and streamflow data for United States and Canadian sites in the Red River Basin and scripts for trend analysis - Data supporting water-quality trend analysis in the Red River of the North basin, 1970-2017
A comprehensive study to evaluate water-quality trends in the international Red River of the North basin and to assess water-quality conditions for Red River of the North crossing the international boundary near Emerson, Manitoba was completed by the U.S. Geological Survey (USGS) in cooperation with the International Joint Commission, North Dakota Department of Environmental Quality (NDDEQ) and Mi
MODFLOW-6 model of the Big Sioux aquifer, Sioux Falls, South Dakota
A MODFLOW-6 groundwater flow model of the Big Sioux aquifer near Sioux Falls in southeastern South Dakota, was constructed to improve the understanding and management of the water supply resources for the City of Sioux Falls.
Supplemental Data for Water-Balance Techniques for Determining Available Soil-Water Storage for Selected Sandy and Clay Soil Study Sites in Cass County, North Dakota, 2016-17
The U.S. Geological Survey, in cooperation with the U.S. Department of Agriculture Natural Resources Conservation Service, collected field and remotely sensed data on precipitation, evapotranspiration (ET), and soil-water content to determine available soil-water storage (AWS) at six study sites on sandy and clay soils in Cass County, North Dakota. Data were collected at all the study sites from M
Lower Brule Reservation Shoreline Erosion, Additional Data Layers, South Dakota, 2018
Additional data layers have been developed to supplement recently published information collected and developed for an investigation of shoreline erosion along the Lower Brule Reservation in Central South Dakota. The additional data layers presented in this data release include georeferenced 1965 single frame aerial photos, digitized shoreline features from the georeferenced 1965 images, digitized
Water-level data and AQTESOLV Pro analysis results for slug tests in the Big Sioux Aquifer, Sioux Falls, South Dakota, 2017
Well and aquifer data were collected from field measurements and drillers' logs. Multiple slug tests were completed at each well with a transducer to record the change in water level and a U.S. Geological Survey standard mechanical slug to displace the well's water column. A Solinst Levelogger LT F30/M10 electronic transducer (unvented) was used to record water-level changes during each slug test.
MODFLOW-NWT model of the glacial aquifer system north of Aberdeen, South Dakota, through water year 2015
A previously developed three-dimensional groundwater flow model (https://doi.org/10.3133/sir20125183) of the three primary aquifers in the region north of Aberdeen, South Dakota, was revised to assist the City of Aberdeen with water-resource planning. The principal aquifers are the Elm, Middle James, and Deep James. The numerical model is intended to be used to (1) simulate hydrologic scenarios o
