A sequence of nine groundwater models was created to study whether underpressures (subhydrostatic heads) in the Paleozoic units underlying the Great Plains of North America are a consequence of Cenozoic uplift of the area. Based on tectonostratigraphic data, we have incorporated into these nine models a cumulative uplift history with superimposed periods of deposition and erosion for the...

The U.S. Geological Survey has operated the Precipitation Chemistry Quality Assurance (PCQA) Project to evaluate and document the data quality for the National Atmospheric Deposition Program (NADP) for 40 years. The PCQA is primarily focused on data quality for the NADP National Trends Network (NTN) and Mercury Deposition Network (MDN). The PCQA implements programs to evaluate the...

ModelMuse is a graphical user interface (GUI) for the U.S. Geological Survey (USGS) models MODFLOW 6, MODFLOW 2005, MODFLOW LGR, MODFLOW LGR2, MODFLOW NWT, MODFLOW CFP, MODFLOW OWHM, MODPATH, ZONEBUDGET, PHAST, SUTRA 2.2, SUTRA 3.0, MT3D USGS, and WellFootprint and the non USGS model MT3DMS. This software package provides a GUI for creating the flow and transport input file for PHAST and...

The Ohio-Kentucky-Indiana WSC/Kentucky Agricultural Development Board choose four parameters to monitor drought: precipitation, streamflow, groundwater level, and crop moisture index. These parameters are frequently used by the Kentucky Drought Mitigation and Response Plan (2008) as indicators of the four stages of drought: drought advisory, moderate drought, severe drought, and extreme...

Sediment composition data to support the manuscript "Multivariate analysis of shale gas development on the chemical and biological health of headwater streams".

Estuaries provide critical habitat for a vast array of fish and wildlife but are also a nexus for core economic activities that mobilize and concentrate contaminants that can threaten aquatic species. Selenium (Se), an essential element and potent reproductive toxin, is enriched in parts of the San Francisco Estuary (SFE) to levels known to cause toxicity, yet the risk of Se to species...

This data release presents results from a laboratory study designed to measure the effect of temperature on rates of oxygen consumption within lake-bottom surface sediments at 0- to 5-cm depth. Sediment and lake water samples were collected June 8, 2016 from the South site in Ashumet Pond, Cape Cod, MA, where lake water recharges to the aquifer. Samples were shipped to Boulder, CO for...

The U.S. Geological Survey is testing deployments of continuous Large-Scale particle Image Velocimetry (LSPIV) streamgaging stations in areas with flashy flow regimes to measure streamflow during flood events. Videos were collected for the purpose of LSPIV streamflow analysis at a stage-discharge streamgaging station in a small, flashy urban stream in Urbana, Illinois, USA (Boneyard...

Clear Lake is a 180 km2 freshwater lake located in the California Coast Range, approximately 120 km northwest of Sacramento. The lake supports a wide variety of fish and bird species and is a very popular sport-fishing destination. However, fish consumption advisories associated with mercury (Hg) contamination exist for several popular recreational species. The lake is comprised of three...

FLASH-R (Flow-Log Analysis of Single Holes) is an R app for the analysis of borehole vertical flow logs to estimate fracture (or layer) transmissivities and far-field hydraulic heads. This app is a new version of the FLASH spreadsheet tool by Day-Lewis et al. (2011) . The program is written in R, an open-source environment. All previous features have been retained and new features...

Areas of groundwater discharge are hydrologically and ecologically important, and yet are difficult to predict at the river network scale. Thermal infrared imagery can be used to identify areas of groundwater discharge based on an observed temperature anomaly (colder during the late summer or warmer during the late winter). The thermal images, direct temperature measurements (11 cm depth...

The U.S. Geological Survey (USGS) National Water Quality Network - Rivers and Streams (NWQN) is comprised of 110 surface-water monitoring sites designed to track ambient water-quality conditions across the nation. Although numerous constituents, including pesticides, have been collected at many of these sites since 1991, glyphosate and its metabolite aminomethylphosphonic acid (AMPA)...
