Data

These data were compiled for modeling efforts of Bureau of Reclamation National Environmental Policy Act (NEPA) analyses for the Colorado River in Grand Canyon, Arizona. Objective(s) of our study were to forecast water temperature, smallmouth bass population growth rate, and smallmouth bass entrainment rates under different water management scenarios. These data represent forecasted...

Forest canopy gap metrics for select floodplain forest canopy gaps in the Upper Mississippi River System (UMRS).

This data release provides forest structure information including basal area and stem density by genus and mortality status for overstory and sapling trees in 149 plots in Whiskeytown National Recreation area in California, USA. The data includes forest structure measurements taken before and after the 2018 Carr Fire, a nearly 93,000 hectare wildfire.

This data release provides documentation on the input and output files used in a seismotectonic study of northern California (see reference below). Files contained in the data release include the station, location and arrivaltime input files to the tomography code and the output relocations and resulting P- and S-wave images. Note that we did not use the S-wave imaging results in the...

This data release contains vector and raster geospatial data for delineating drainage basins in the Nevada StreamStats study area. Included are vector streamline, waterbody, and inner wall data used to hydrologically condition the digital elevation model. The hydrologically-conditioned digital elevation model, flow direction, flow accumulation, and stream delineation raster data are also...

In cooperation with the South Carolina Department of Transportation, the U.S. Geological Survey updated the foundational geospatial layers for the South Carolina StreamStats web application (https://water.usgs.gov/osw/streamstats/), which provides analytical tools useful for water-resources planning and management (Kolb and others, 2018). This dataset presents the digital elevation model...

In May 2021, the Grand Canyon Monitoring and Research Center (GCMRC) of the U.S. Geological Survey’s (USGS), Southwest Biological Science Center (SBSC) acquired airborne multispectral high resolution data for the Colorado River in Grand Canyon in Arizona, USA. The imagery data consist of four bands (Band 1 – red, Band 2 – green, Band 3 – blue, and Band 4 – near infrared) with a ground...

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...

These shapefiles represent the frequency characteristics of soil moisture, evapotranspiration, and climatic water deficit for Kauaʻi, Oʻahu, Molokaʻi, Maui, and the Island of Hawaiʻi for a set of water-budget scenarios that characterize unique combinations of rainfall and land-cover conditions. Four water-budget scenarios were developed to quantify the effects of drought on soil moisture...

To better inform fuel break planning and assessment, we developed a comprehensive spatial database of known existing fuel breaks from 1953 to 2018 throughout the western United States. Each fuel break is represented as a polygon in the database and is attributed with the date of installation, the treatment type employed, and the data source. The availability of these data promotes the...

This data release contains monthly 270-meter resolution Basin Characterization Model (BCMv8) climate and hydrologic variables for Localized Constructed Analog (LOCA; Pierce et al., 2014)-downscaled Global Climate Models (GCMs) for Representative Concentration Pathway (RCP) 4.5 (medium-low emissions) and 8.5 (high emissions) for hydrologic California. The 20 future climate scenarios...

This data release contains model results for groundwater response to sea-level rise (SLR) in coastal areas around Puget Sound, Washington. The high resolution (50m) models predict steady-state unconfined groundwater heads under long-term (17y) average recharge conditions, with spatially variable hydraulic conductivities (Ks) from published models, and include model runs with Ks increased...
