USGS StreamStats: Hydrologic and Geospatial Data

USGS StreamStats: Hydrologic and Geospatial Data Integrated to Support Water Science and Management

StreamStats (http://streamstats.usgs.gov) is a U.S. Geological Survey web-service-based geographic information services application that provides information used by engineers, hydrologists, managers, planners, and others to make informed decisions on water-related activities. It integrates multiple datasets, such as the National Hydrography Dataset (NHD), the Watershed Boundary Dataset, and the 3D Elevation Program, to allow users to delineate a watershed for a stream point of interest. The principal benefit of StreamStats is that the delineation process that used to take hours now can be accomplished in a matter of minutes, and is replicable between users. StreamStats users can also calculate flow statistics for the watershed of interest and compute basin characteristics such as National Land Cover Dataset land use/land cover values and average precipitation. Future enhancements will include network navigation tools to trace up and downstream on the NHD flowlines, as well as time of travel.
