These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. These data represent the thickness, in feet, of the Upper Hell Creek hydrogeologic unit in the Powder River basin. The data are presented as ASCII text files that can be converted to continuous raster format.

These data represent the extent of the Fox Hills aquifer in the Powder River and Williston structural basins.
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This feature class represents the southern extent of glacial deposits in the Williston Structural basin.
This dataset is a continuous parameter grid (CPG) of normal (average) annual precipitation data for the years 1981 through 2010 in the Pacific Northwest. Source precipitation data was produced by the PRISM Climate Group at Oregon State University.
These datasets are continuous parameter grids (CPG) of first-of-month snow water equivalent data for March through August, years 2004 through 2016, in the Pacific Northwest. Normal (average) first-of-month values for the same months, averaged across all years, are also located here. Source snow water equivalent data was produced by the Snow Data Assimilation System (SNODAS) at the National Snow and Ice Data Center.
These datasets are continuous parameter grids (CPG) of permeability (and impermeability) of surface geology in the Pacific Northwest. Source data come from work by Chris Konrad, U.S. Geological Survey (USGS), and geologic map databases produced by USGS scientists.
This table is a crosswalk or lookup table that classifies rock type (surface geology) by its permeability, or the ability to pass substances, such as liquids or gases. The rock types that are classified are located in the Northwest U.S. -- Oregon, Washington, Idaho, Utah, Nevada, Wyoming, and Montana.
To improve understanding of streamflow permanence in the Pacific Northwest, we have developed a method for predicting the annual probability of year-round streamflow at 30-meter intervals. The approach involves collecting and processing nearly 24,000 streamflow observations into “wet” or “dry” values, and synchronizing them with 291 predictor datasets that represent physical (one-time values) and climatic (monthly or annual values) conditions associated with the upstream area for each 30-meter point along streams in the Pacific Northwest. Both of these datasets are among the first of their kind and shed light on the scientific opportunities that ‘Big Data’ techniques allow for. The predictive models developed from...
Mountain meadows in the western United States provide key habitats for many plant and wildlife species, many of which rely exclusively on these areas. Mountain meadows are also treasured by the public and provide beautiful areas to view wildflowers and wildlife on public lands such as national parks. However, mountain ecosystems are expected to be disproportionately affected by climate change. There is a limited understanding of how mountain meadows are changing, how temperature and precipitation may be driving those changes, and how this will impact sensitive species that inhabit these landscapes. Natural resource managers have an immediate need to understand these relationships to conserve or restore habitats...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. These data represent the altitude, in feet above North American Vertical Datum of 1988 (NAVD88), of the lower Fort Union aquifer in the Williston structural basin. The data are presented as ASCII text files that can be converted to continuous raster format.

This dataset is a continuous parameter grid (CPG) of normal (average) annual maximum air temperature data for the years 1981 through 2010 in the Pacific Northwest. Source temperature data was produced by the PRISM Climate Group at Oregon State University.
These datasets are continuous parameter grids (CPG) of topography data in the Pacific Northwest. Datasets include stream slope, basin slope, elevation, contributing area, and topographic wetness index. Source data come from the U.S. Geological Survey National Elevation Dataset.
The U.S. Geological Survey (USGS) has developed the PRObability of Streamflow PERmanence (PROSPER) model, a GIS raster-based empirical model that provides streamflow permanence probabilities (probabilistic predictions) of a stream channel having year-round flow for any unregulated and minimally-impaired stream channel in the Pacific Northwest region, U.S. The model provides annual predictions for 2004-2016 at a 30-m spatial resolution based on monthly or annually updated values of climatic conditions and static physiographic variables associated with the upstream basin. These values and variables, known as Continuous Parameter Grids, or CPGs, were used as the predictor variables in the model. The CPGs referenced...
