Pesticides in Weekly Water Samples from the NAWQA Midwest Stream Quality Assessment (2013)

Dissolved pesticides were measured in weekly water samples from 100 wadeable streams across eleven states in the Midwestern U.S. during May-August, 2013, as part of the Midwest Stream Quality Assessment study conducted by the U.S. Geological Survey's (USGS) National Water Quality Assessment (NAWQA) Project. Of the 100 stream sites, 12 were urban indicator sites and the remaining 8

Madison River near West Yellowstone, MT (YMAD)

Madison River near West Yellowstone, MT (YMAD), Yellowstone National Park Sample Collection: Samples were collected near the USGS stream gage 06037500 (Latitude 44°39'25.46", Longitude 111°04'04.67" NAD83). At the time of collection, all waters samples were filtered through a syringe filter (0.45-micrometer). Two splits of the filtered water were reta

MODFLOW-NWT, MODPATH, and MT3DMS models used to study of hypothetical horizontal water-supply well design for New Hampshire and surrounding regions: U.S. Geological Survey data release

A series of three-dimensional, hypothetical, groundwater models (MODFLOW-NWT) were developed to
investigate the effects of a variety of factors on the flow of arsenic-containing water into a well. The well
is of novel design with a constructed aquifer providing storage. The models simulate a hillslope with till
overlying a fractured bedrock aquifer as is common in New England...

Supporting Data QC Field Spikes SW NAWQA 2012-2015

Field spikes were prepared at 207 stream and river sites as part of the U.S. Geological Survey (USGS) National Water Quality Assessment (NAWQA) project between December, 2012, and September, 2015. At the field site, a depth-and width-integrated environmental sample was collected, and one subsample of the environmental sample was spiked with a known amount of a spike mixture. Bot

Modeled temperature data developed for study of shallow mountain bedrock limits seepage-based headwater climate refugia, Shenandoah National Park, Virginia: U.S. Geological Survey data release

1D transient numerical simulations with a modified version of the SUTRA model
(preliminary code) that accounts for variably-saturated freeze-thaw dynamics
(e.g. McKenzie and Voss, 2013) to predict annual alluvial aquifer temperature
dynamics using coupled fluid and heat transport physics. The model simulations
were run with a modified version of SUTRA_ICE (unreleased)...

Ecological community datasets used to evaluate the presence of trends in ecological communities in selected rivers and streams across the United States, 1992-2012 (output)

In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project of the National Water-Quality Program. One of the major goals of the NAWQA project is to determine how water-quality and ecological conditions change over time. To support that goal, long-term consistent and com

Source and model output layers used for the prediction and display of the probability of elevated concentrations of redox-sensitive constituents in groundwater in the Fox-Wolf-Peshtigo watershed in Wisconsin and Michigan

This USGS data release contains 1-kilometer resolution source-layer rasters used to predict redox conditions and contaminant concentrations in groundwater in the Fox-Wolf-Peshtigo watershed in Wisconsin and Michigan using random forest classification. The model output layers are 1-kilometer resolution rasters of the predicted probability of elevated concentrations of nitrate, iron, and arseni...

MODFLOW-NWT model used in simulation of groundwater flow and availability in the North Fork Red River aquifer, southwest Oklahoma, 1980-2013

In 2017 the U.S. Geological Survey, in cooperation with the Oklahoma Water Resources Board, published a
calibrated numerical groundwater-flow model and associated model documentation report that evaluated the effects
of potential groundwater withdrawals on groundwater flow and availability in the North Fork Red River aquifer in
southwest Oklahoma. The results of groundwater-...

Phytoplankton Species Composition, Abundance and Cell Size in San Francisco Bay: Microscopic Analyses of USGS Samples Collected 1992-2014

This Data Release makes available measurements of phytoplankton species composition, abundance and cell size made on samples collected in San Francisco Bay (CA) from April 1992 through March 2014. Phytoplankton samples were collected at 31 stations along a 145-km transect where the variability of salinity, temperature, turbidity and nutrient concentrations reflected a broad range of env
