This dataset consists of altitudes of 18 springs located throughout the study area which were used in construction of the potentiometric-surface map. Springs were selected from the previously published report by Kresse and Hays (2009), and site reconnaissance. Surface-water features and springs represent the intersection of the groundwater-table with land surface. Spring altitudes were calculated from 10-meter digital elevation model (DEM) data (U.S. Geological Survey, 2015; U.S. Geological Survey, 2016) . Select References: Kresse, T.M., and Hays, P.D., 2009, Geochemistry, Comparative Analysis, and Physical and Chemical Characteristics of the Thermal Waters East of Hot Springs National Park, Arkansas, 2006-09:...

groundwater and surface-water interaction,
Of the approximately 6.6 million people living in the Mississippi embayment (MISE) region in the central United States, approximately 65 percent rely on groundwater for their drinking water (Dieter, Linsey, and others, 2017). Regional assessments of water quality in principal aquifer systems provide context for the long-term availability of these water resources for drinking-water supplies. To assess the current (2018) status of water quality in MISE in relation to drinking water supplies, groundwater withdrawal zones used for domestic and public supply were modeled using available groundwater well and hydrogeologic framework data. Three dimensional surfaces were modeled to map the depth zones at which groundwater...

Leavenworth Creek, a tributary of South Clear Creek and Clear Creek near Georgetown, Colorado contains copper, lead, and zinc concentrations that are near to or exceed aquatic life standards. The creek drains the Argentine mining district where mining was active primarily in the early 1900s. In the summer of 2012, the U.S. Geological Survey (USGS) conducted a metal-loading study using tracer dilution and spatially detailed synoptic sampling to assess the location and magnitude of copper, lead, manganese, and zinc sources to Leavenworth Creek. Sodium bromide solution was injected into the stream to facilitate calculation of stream discharge at all stream sites using the principles of tracer dilution. Consequently,...

The Captain Jack Superfund site near Ward, Colorado hosts extensive interconnected underground mine workings, which drain via the Big Five Adit. Drainage from the adit has historically been acidic with elevated concentrations of metals. In 2018 the U.S. Environmental Protection Agency (EPA) utilized a subsurface remediation strategy consisting of the installation of a hydraulic bulkhead within the workings to preclude drainage out of the mine. To understand the processes occurring during water impoundment within the mine workings, the U.S. Geological Survey (USGS), in cooperation with EPA, completed water-quality sampling and analysis during 2020 as water was impounded within the mine workings. The USGS sampling...

From 2016 through 2018, the U.S. Geological Survey, in cooperation with the New York State Department of Environmental Conservation, collected horizontal-to-vertical seismic soundings at 71 locations in the major valleys in the Oneonta area, Otsego and Delaware Counties, New York to help determine thickness of the unconsolidated deposits and the bedrock surface elevation. The HVSR technique, commonly referred to as the passive-seismic method, is used to estimate the thickness of unconsolidated sediments and the depth to bedrock (Lane and others, 2008; Fairchild and others, 2013). The passive-seismic method uses a single, broad-band three-component (two horizontal and one vertical) seismometer to record ambient seismic...

Two tributary watersheds¬ Cottonwood Creek and Little Dry Creek¬ to the greater San Joaquin watershed, in California’s Central Valley were assessed for sediment and flow dynamics, between water years (Oct. 1 to Sept. 30) 2011 and 2019. The two systems deliver suspended sediment to the San Joaquin River below Friant Dam, California. Because these two creeks are directly down river of Friant Dam, they become the most upstream source of sediment to the San Joaquin River below Friant Dam. Thus, is it important to assess their contribution to the San Joaquin system. Flow from each creek watershed, along with the San Joaquin River, was compared to continuously measured water surface elevations to quantify flow direction...

Bottom altitudes of the Mississippi River Valley alluvial aquifer (MRVA) were compiled from interpretations of subsurface geophysical logs (log picks) at about 10,000 boreholes and wells located throughout the Mississippi Alluvial Plain (MAP) that were available from previous investigations. Five sources of the bottom altitude data are listed numerically in the Cross Reference section (below) and correspond with the Ref_code listed in the .shp dataset. Borehole geophysical data (log picks) were referenced (corrected) to the National Elevation Dataset (NED) 10-meter digital elevation model (DEM; https://nationalmap.gov/elevation.html). Log picks that required a DEM correction of less than 20 feet were retained for...

This data set contains two sets of measured water-level data collected on and near Offutt Air Force Base near Bellevue, Nebraska. Surface-water and groundwater-level data were collected for two synoptic water-level surveys completed in late summer of 2020 and in spring 2021. The elevations of surface-water features were surveyed with a rover receiver using a real-time network (RTN), where the rover receiver receives real-time position corrections from a central server through a mobile wireless-fidelity (Wi-Fi) hotspot linked to the rover receiver. Data collection procedures ensured that positions and elevations achieved a U.S. Geological Survey (USGS) Level-III survey accuracy and surveyed surface-water elevations...

This data release provides the results of the bathymetric survey of the Similkameen River directly above Enloe Dam which took place over three days in late September 2020. The bathymetric survey was completed to enable an instrument-based estimate of the volume of legacy sediment impounded behind Enloe Dam. A shoreline water level survey collected points at the river’s edge using Trimble R8 GNSS Receivers. Safety requirements directly upstream of the dam made a ground survey infeasible, thus shoreline points were inferred from the National Agricultural Imagery Program (NAIP) 2015 imagery corrected to Okanogan County lidar. The study area polygon was constructed from the shoreline points with a 0.5m buffer applied....
