Download National Datasets

Data collected and managed by Forest Service programs is available in a map service and two downloadable file formats – in a shape file and an ESRI file geodatabase. Metadata is available that describes the content, source, and currency of the data. You can filter the list by the topic categories in the menu at the left to help you find information you are interested in. You can view the feature classes in a single dataset by clicking on the name of the parent dataset at the bottom of the abstract.

EDW Information, Updates, and Alerts:

Check the EDW Information, Updates, and Alerts page for the latest Enterprise Data Warehouse notifications.

Shapefiles do not exist for all National Datasets.
This format has technical limitations which make them unsuitable for multiple datasets within this clearinghouse. These constraints include file size, attribute name length, field length, number of fields, limited data types, lack of topological representations and floating-point rounding errors leading to inevitable data loss. The EDW Team is unable to support Shapefile exports for datasets that approach those limits. Esri File Geodatabases (FGDB) will remain available. Alternative formats including GeoPackage, GeoJSON, Character Separated Values (CSV), Map Services and Geospatial Discovery Tool offerings will be used to provide open format access to these National Datasets. Once these formats are available for all National Datasets, EDW will retire the shapefile format as a supported file exchange format.

Requests for KML/KMZ output
The Enterprise Data Warehouse Team tested exporting out to KML/KMZ files as a deliverable and due to the complexity and size of the datasets this has been unsuccessful. To obtain a KML file for any EDW dataset, go to the Geospatial Data Discovery Tool and search for the dataset. An option to download to KML is available from that website.

Feature Classes Abstract

Fraction of Runoff from Forest Service Lands

ESRI geodatabase  (664MB)
shape file  (1121MB)

Date of last refresh: Apr 3, 2019

This feature class contains water runoff metrics from Forest Service lands. Note: 'Forest Service Lands' are here defined as those lands within the Forest Service administrative boundaries; these include some inholdings and other non-USFS lands enclosed within these boundaries. This feature class was generated from the original study "Modeled historical streamflow metrics for the contiguous United States and National Forest Lands" (Luce, et. al., 2017) and the 2012 snapshot of the stream layer from the National Hydrography Dataset (NHD). More information pertaining to the original streamflow dataset is available on the Research Data Archive: https://www.fs.usda.gov/rds/archive/Product/RDS-2017-0046.

Purpose:
Available water supply varies greatly across the United States depending on topography, climate, elevation and geology. Forested and mountainous locations, such as national forests, tend to receive more precipitation than adjacent non-forested or low-lying areas. However, contributions of national forest lands to regional streamflow volumes is largely unknown. This streamflow metrics feature class provides a high resolution, spatially explicit estimate of annual and summer flow volumes that can be used in more extensive studies of water quantity and water quality. In addition, the dataset highlights the relative importance of national forest lands to overall water quantity.

Great Basin Montane Watersheds - Furthest Head

Multiple research and management partners collaboratively developed a multiscale approach for assessing the geomorphic sensitivity of streams and ecological resilience of riparian and meadow ecosystems in upland watersheds of the Great Basin to disturbances and management actions. The approach builds on long-term work by the partners on the responses of these systems to disturbances and management actions. At the core of the assessments is information on past and present watershed and stream channel characteristics, geomorphic and hydrologic processes, and riparian and meadow vegetation. In this report, we describe the approach used to delineate Great Basin mountain ranges and the watersheds within them, and the data that are available for the individual watersheds. We also describe the resulting database and the data sources. Furthermore, we summarize information on the characteristics of the regions and watersheds within the regions and the implications of the assessments for geomorphic sensitivity and ecological resilience. The target audience for this multiscale approach is managers and stakeholders interested in assessing and adaptively managing Great Basin stream systems and riparian and meadow ecosystems. Anyone interested in delineating the mountain ranges and watersheds within the Great Basin or quantifying the characteristics of the watersheds will be interested in this report. For more information, visit: https://www.fs.usda.gov/research/treesearch/61573

Purpose:
The Great Basin Montane Watersheds dataset is the result of research assessing the geomorphic sensitivity of streams and ecological resilience of riparian and meadow ecosystems in upland watersheds of the Great Basin to disturbances and management actions. The study area, the Great Basin of North America, includes portions of Nevada, Utah, California, Oregon, and Idaho. Nine feature classes are included, which provide the seven regions (1) and the mountain ranges (2) identified in the study area, streams within each watershed (3) along with the stream heads (4), longest stream (5), lowest drainage points (6), and the stream head that has the farthest stream distance from the pour point (7), and the valley bottom which is considered the area surrounding the stream that is less than 15 meters above the stream's elevation (8) for each watershed. Also included are the watershed boundaries (9) and additional watershed information related to climate, topography, and wildlife.

This layer indicates the location of the observed stream temperature records used for the NorWeST database summaries. NorWeST summer stream temperature scenarios were developed for all rivers and streams in the western U.S. from the > 20,000 stream sites in the NorWeST database where mean August stream temperatures were recorded. The resulting dataset includes stream lines (NorWeST_PredictedStreams) and associated mid-points NorWest_TemperaturePoints) representing 1 kilometer intervals along the stream network. Stream lines were derived from the 1:100,000 scale NHDPlus dataset (USEPA and USGS 2010; McKay et al. 2012). Shapefile extents correspond to NorWeST processing units, which generally relate to 6 digit (3rd code) hydrologic unit codes (HUCs) or in some instances closely correspond to state borders. The line and point shapefiles contain identical modeled stream temperature results. The two feature classes are meant to complement one another for use in different applications. In addition, spatial and temporal covariates used to generate the modeled temperatures are included in the attribute tables at https://www.fs.fed.us/rm/boise/AWAE/projects/NorWeST/ModeledStreamTemperatureScenarioMaps.shtml. The NorWeST NHDPlusV1 processing units include: Salmon, Clearwater, Spokoot, Missouri Headwaters, Snake-Bear, MidSnake, MidColumbia, Oregon Coast, South-Central Oregon, Upper Columbia-Yakima, Washington Coast, Upper Yellowstone-Bighorn, Upper Missouri-Marias, and Upper Green-North Platte.
