MODFLOW-NWT model data sets for simulating effects of groundwater withdrawals on streamflows in Northwestern Chippewa County, Wisconsin

Paul F Juckem, Michael N Fienen & Megan J Haserodt
A new groundwater flow model for western Chippewa County, Wisconsin has been developed by the Wisconsin Geological and Natural History Survey (WGNHS) and the U.S. Geological Survey (USGS). An analytic element GFLOW model was constructed and calibrated to generate hydraulic boundary conditions for the perimeter of the more detailed three-dimensional MODFLOW-NWT model. This three-dimensional model uses the USGS MODFLOW-NWT finite difference code, a standalone version of MODFLOW-2005 that incorporates the Newton (NWT) solver. The model...

U.S. Geological Survey - Gap Analysis Project Species Habitat Richness

Kevin Gergely, Kenneth Boykin, Alexa McKerrow, Matt Rubino, Nathan Tarr & Steven Williams
The Species Richness Maps included here are based on the Gap Analysis Project (GAP) habitat maps, which are predictions of the spatial distribution of suitable environmental and land cover conditions within the United States for individual species. Individual species habitat distribution models were summed to create the total richness for each vertebrate taxa. The summing process was coded in Python 2.7 and employed the arcpy module for geoprocessing steps. The code is documented in the...

Percent of Agriculture Land Subject to Select National Resource Inventory Conservation Practices, 2000-2012

Michael E. Wieczorek
This metadata record describes 26 30-meter raster data sets that estimate the percent of agricultural land that may be subject to select conservation practices for each year during the period 2000-2012. The data were derived from U.S. Department of Agriculture (USDA) National Resources Conservation Service (NRCS) National Resource Inventory (NRI). One set of rasters (denoted by the ICP prefix) represents an estimate of the percent of agricultural land potentially subject to Alley Cropping, Contour Buffer...

Data Release for Lake Shadow Seepage Calculations from Ashumet Pond, Cape Cod, MA, 2016 - 2018

R.B. Hull, Martin Briggs, Denis R LeBlanc, David S Armstrong & Timothy D McCobb
Hydrologic data were collected in the nearshore lake-bottom sediments of five lakes on western Cape Cod, Massachusetts: Ashumet (Falmouth), Long (Centerville), Santuit (Mashpee), Shubael (Barnstable), and Snake (Sandwich) Ponds. Water budgets of flow-through glacial kettle lakes are commonly dominated by groundwater flow into and surface-water seepage out of the lake, and inputs and losses from precipitation and evaporation are typically smaller. This data release presents water flux data collected from sites at the five lakes...

Data for Assessing the Status of Macroinvertebrate Communities and Sediment Toxicity in the Buffalo River Area of Concern, New York

Brian T. Duffy, Barry P. Baldigo & Scott D. George
Data from 10-day sediment toxicity tests of bed sediments from the Buffalo River Area of Concern (AOC) and reference reaches on the Buffalo River upstream of the AOC, Erie County, New York, respectively. Specifically, the data was used to compare the survival and growth of two macroinvertebrate species in sediments from study sites and laboratory controls. Results are from 10-day sediment exposures of two test species, Chironomus dilutus and Hyalella azteca. Sediment samples were collected...

Genetics rayed creekshell

Nathan A. Johnson
This dataset supports the inclusion of Anodontoides radiatus in the genus Strophitus, introducing the binomial Strophitus radiatus. These data also provide strong support for paraphyly in Strophitus and advocate the resurrection of the genus Pseudodontoides to represent the binomials Pseudodontoides connasaugaensis and Pseudodontoides subvexus.

Stephen T. Bosse, James G. Flocks & Arnell S. Forde
This data release serves as an archive of HRSP profiles annotated with header information, converted SEG-Y files, navigation data, and cruise trackline shapefiles. The HRSP data were collected using a Huntec boomer seismic system onboard the Research Vessels (R/V) R.J. Russell and Carancahua. While on the R/V R.J. Russell, geophysical surveys were conducted at various times between December 1982 and July 1984 with the data being acquired from waterbodies surrounding Isles Dernieres (Lacoss 82-2, 83-3...

Data Release of OSL, 14C, and U-series age data supporting geologic mapping along the South Platte River corridor in northeastern Colorado

Margaret E. Berry, James B. Paces, Paul R. Hanson, Emily M. Taylor & Janet L. Slate
In conjunction with geologic mapping of four 7.5′ quadrangles along the South Platte River corridor in northeastern Colorado (Masters, Orchard, Weldona, and Fort Morgan), geochronology samples were collected and analyzed using optically stimulated luminescence (OSL), radiocarbon (14C), or U-series methods to provide age control for mapping units. This section of river corridor is largely covered by surficial deposits that formed from alluvial, eolian, and hillslope processes operating in concert with environmental changes from the Pleistocene...
