Spatial data: Projected shifts in fish species dominance in Wisconsin lakes under climate change

Temperate lakes may contain both coolwater fish species such as walleye (Sander vitreus) and warmwater species such as largemouth bass (Micropterus salmoides). Recent declines in walleye and increases in largemouth bass populations have raised questions regarding the future trajectories and appropriate management actions for these important species. We developed a thermodynamic model of

Groundwater discharge area for Diamond Valley, Central Nevada, 1968

This dataset represents "phreatophyte areas" mapped as part of an analysis of irrigation pumping
in Diamond Valley, Nevada published in 1968. The data were digitized for comparison with mapping
of groundwater discharge areas done in 2011 as part of a groundwater study in these valleys published
in 2016.

Groundwater discharge areas for Antelope, Kobeh, and Monitor Valleys, Central Nevada, 1964

This dataset represents "phreatophyte areas" mapped as part of a groundwater reconnaissance
effort in four valleys in central Nevada and published in 1964. The data were digitized for comparison
with mapping of groundwater discharge areas done in 2011 as part of a groundwater study in these
valleys published in 2016.

Lower Rio Puerco 2005 georeferenced aerial photographs

High-resolution (0.20 m) digital images collected during an aerial LiDAR survey of the Lower Rio Puerco during April and July 2005. Details on data collection and processing methods are provided in an unpublished report by Spectrum Mapping, LLC (August 2005; see Supplemental Information). The images are Spectral Imagery LiDAR Composite (SILC) in which individual image pixels have

HEC-HMS and HEC-RAS models used to analyze dam failure for the Lago El Guineo Dam, Orocovis, Puerto Rico

The Hydrologic Engineering Center’s Hydrologic Modeling System (HEC-HMS) and Hydrologic Engineering
Center’s River Analysis System (HEC-RAS) computer programs, developed by the U.S. Army Corps of
Engineers, were used for the hydrologic and hydraulic modeling, respectively, to analyze the potential for
dam failure under different hydrologic conditions. The

Aquatic insect community data and taxa list for larvae collected from mesocosms exposed to bifenthrin

Direct and indirect ecological effects of the widely used insecticide bifenthrin on stream ecosystems are largely unknown. To investigate such effects, a manipulative experiment was conducted in stream mesocosms that were colonized by aquatic insect communities and exposed to bifenthrin-contaminated sediment; implications for natural streams were interpreted through comparison of mesocosm res...

SEAWAT model used to evaluate the potential effects of alterations to the hydrologic system on the distribution of salinity in the Biscayne aquifer in Broward County, Florida: U.S. Geological Survey Data Release

A three-dimensional, variable-density solute-transport model (SEAWAT) was developed to examine
causes of saltwater intrusion and predict the effects of future alterations to the hydrologic system
on salinity distribution in eastern Broward County, Florida. The model was calibrated to conditions
from 1970 to 2012, the period for which data are most complete and reliable, and w...

Depth to 50 percent probability of oxic conditions, Chesapeake Bay Watershed

This dataset is a 900 meter resolution raster representing the depth in meters at which the probability of oxic groundwater occurring is at least 50%, for the Chesapeake Bay watershed. Oxic groundwater was defined as containing O2 values >= 2 mg/L. The values range from 0-100 meters, with 100 representing all depths greater than 100. It was created in support of models which define th

Geochemical Characteristics of the Conterminous United States: % MgO

This raster depicts the percentage of lithological magnesium oxide (MgO) content in surface or near surface geology. We derived these rasters by calculating the average percent MgO content for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355, 2005-1305%
