GAGES-II: Geospatial Attributes of Gages for Evaluating Streamflow

Dates

Publication Date

Summary

This dataset, termed "GAGES II", an acronym for Geospatial Attributes of Gages for Evaluating Streamflow, version II, provides geospatial data and classifications for 9,322 stream gages maintained by the U.S. Geological Survey (USGS). It is an update to the original GAGES, which was published as a Data Paper on the journal Ecology's website (Falcone and others, 2010b) in 2010. The GAGES II dataset consists of gages which have had either 20+ complete years (not necessarily continuous) of discharge record since 1950, or are currently active, as of water year 2009, and whose watersheds lie within the United States, including Alaska, Hawaii, and Puerto Rico. Reference gages were identified based on indicators that they were the least-disturbed [...]

Purpose

This dataset has two purposes: (1) to provide users with a comprehensive set of geospatial characteristics for a large number of gaged watersheds, particularly for gages with long flow record, and (2) to provide a determination of which of those watersheds represent hydrologic conditions which are least disturbed by human influences ("reference gages"), compared to other watersheds within 12 major ecoregions. Identifying reference gages serves important research goals: for example identifying conditions or goals for stream restoration, climate change studies, and more.
