Characterizing Ecoregions and Montane Perennial Watersheds of the Great Basin - Stream Heads
vector digital data
http://data.fs.usda.gov/geodata/edw/datasets.php
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.

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.

Stream heads were determined by identifying dangling nodes within the watershed that were not the pour point. A dangling node is a line start/end point that does not connect to any other line.
All channel heads were mapped in a consistent manner. They are all defined using the 4000 cell flw accumulation threshold.
This dataset is derived from 1/3 arc-second Digital Elevation Models obtained from the U.S. Geological Survey National Elevation Dataset, which has (approximately 10 m) resolution, equating to roughly to a 1:24,000 horizontal resolution.
