Specific Conductance Data for Selected Rivers and Creeks in Yellowstone National Park, beginning in 2010

Monitoring the chloride (Cl) flux in the major rivers draining Yellowstone National Park (YNP) provides a holistic view of the thermal output from the underlying magma chamber, and abrupt fluctuations in the Cl flux may signify changes in thermal activity. The U.S. Geological Survey (USGS) and the National Park Service (NPS) have collaborated on Cl flux monitoring of the major r

MODFLOW-2005 and MODPATH6 models used to simulate groundwater flow and nitrate transport in two tributaries to the Upper Chester River, Maryland

A previously developed steady state three-dimensional groundwater flow
(MODFLOW-2005) and advective transport (MODPATH6) model was
used to examine subsurface nitrate transport to wells and receiving
streams in two subcatchments contributing to the Upper Chester River,
Maryland. Multiple scenarios of flow and transport parameter fields
(recharge, hydraulic...

Application of hierarchical Bayesian methods to a spatially explicit model of long-term mean annual streamflow for the conterminous United States

The data release documents the application of hierarchical Bayesian
methods to a previously developed hybrid (statistical-mechanistic)
SPARROW (SPAtially Referenced Regression On Watershed attributes)
model of long-term mean annual streamflow for streams and rivers of
conterminous United States. The performance and interpretability of
three models were evaluated....

Field measurements of water column optical properties from the upper Sacramento River in northern California, September 13, 2017, and similar data from several other rivers

Field measurements of various optical properties of the water column were acquired from a reach of the upper Sacramento River in northern California, September 13, 2017, to support research on remote sensing of rivers, particularly estimation of water depth from passive optical image data. The field measurements included in this data release include several parameters measured with three

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, South Dakota,
was constructed to improve the understanding and management of the water supply resources for
the City of Sioux Falls. The model area included the Big Sioux River drainage basin between Del
Rapids and Sioux Falls, South Dakota, and simulated groundwater flow in the Big Sioux aquifer...

Hydrographic surveys collected to support fish spawning reef placement, Detroit River, Michigan, June 23-24, 2015

The U.S. Geological Survey conducted hydrographic surveys from June 23-24, 2015 to monitor fish spawning substrate placements (reefs) in the Detroit River, MI. An interferrometric multibeam echosounder was used from the Great Lakes Science Center research vessel Mayfly to collect maps of river bottom topography in locations where spawning substrates have been placed. In addition, baseli

Langelier Saturation Indices Computed for U.S. Groundwater, 1991-2015; Water Well Data and Characteristic Values for States

The occurrence of metals, such as lead and copper, in household drinking supplies can often be a result of the corrosion of pipes and joints in water distribution systems. One measure of the potential for water to cause corrosion is the Langelier Saturation Index (LSI).

Corrosivity index and streamflow datasets used to evaluate trends in potentially corrosive source waters in the Nation's streams and rivers

Changes in water corrosivity from 84 river sites were investigated using long-term data sets.   As part of the National Water-Quality Assessment (NAWQA) project of the National Water-Quality Program, long-term water-quality data from multiple sites across the Conterminous United States have been used to analyze seasonal- and flow-related variability and trends in the CSMR and LR indices.
