Data

A comprehensive study to evaluate water-quality trends in the International Souris River Basin, Saskatchewan and Manitoba, Canada and North Dakota, United States was completed by the U.S. Geological Survey (USGS) in cooperation with the International Joint Commission. In this dataset all files necessary to run trend models and produce results published in U.S. Geological Scientific Investigations

This data release contains electrical resistivity tomography (ERT) and passive seismic data collected east of Ellsworth Air Force Base, South Dakota, from April to September 2021. The data accompanies a USGS scientific investigations map from Medler (2022). The U.S. Geological Survey, in cooperation with the U.S. Air Force Civil Engineer Center, used surface geophysical methods to delineate the t

This data release contains borehole geophysical data collected within and near Ellsworth Air Force Base, South Dakota, from September 2020 to August 2021. The data accompanies a USGS scientific investigations map from Medler and others (2022). The U.S. Geological Survey, in cooperation with the U.S. Air Force Civil Engineer Center, collected borehole geophysical data and performed simple aquifer

This page contains a zipped folder which contains all items necessary to run trend models and produce results published in U.S. Geological Scientific Investigations Report 2022-5086 [Tatge, W.S., Hoogestraat, G., and Nustad, R.A., 2022, Water-Quality Data and Trends in the Rapid Creek Basin, South Dakota, 1970–2020: U.S. Geological Survey Scientific Investigations Report 2022-5086]. To run the R-Q

A comprehensive study to evaluate salinity and nutrient conditions in the Heart River Basin, North Dakota was completed by the U.S. Geological Survey (USGS) in cooperation with the Natural Resources Conservation Service and the Grant County Soil Conservation District. In this dataset three zipped folders are provided which contain all files necessary to run trend, load, and geochemical models and

The City of Mitchell, South Dakota is exploring ways to improve water quality in Firesteel Creek, which flows into Lake Mitchell. One possible way is to construct a wetland on City-owned land in the Firesteel Creek floodplain above Lake Mitchell, allowing sediment deposition and nutrient uptake by aquatic vegetation in the constructed wetland. In order for a constructed wetland to be designed, inf

This data release is a collection of hydrologic characteristics of groundwater and surface water of selected lakes (Dry Lake #1 and #2, and Antelope Lake) within Clark County, South Dakota. The compiled data was broken into two parts, Reports and Maps, and GIS Data. The Reports and Maps dataset contains PDF reports, maps, and logs for aquifers, lake bathymetry, lithology, and observation wells nea

This data release contains borehole video and aquifer-test data for the Burnpit well (U.S. Geological Survey [USGS] National Water Information System identification 435240103265301), Mount Rushmore National Memorial, collected in June and July 2020. The data accompany a USGS Scientific Investigations Report by Eldridge and others (2021).

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

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

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

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
