US Environmental Protection Agency, and US Geological Survey, 20150101, Gage Locations (GageLoc.shp) indexed to the NHDPlus Version 2.1 stream network: .

Summary

The locations of approximately 26,000 current and historical U.S. Geological Survey (USGS) surface-water monitoring gaging stations have been indexed to the NHDPlus Version 2.1 stream network. Part of the USGS National Water Information System (NWIS), these gaging stations measure water flow and water levels in streams and lakes. The NHDPlus V2 stream network locations for these gaging stations differ from stations' latitude/longitude provided in NWIS. The NWIS coordinates are frequently not coincidenet with the NHDPlus stream network.

Purpose

The purpose of this dataset is to provide the locations of USGS gaging stations indexed to the NHDPlus Version 2.1 linear stream network. Considerable review and revision has gone into the NHDPlus locations provided in this dataset. For each USGS gaging station, the station ID, and the NHDPlus Reachcode and Measure are provided. The ComID (common identifier) of the NHDFlowline feature of the gage location is also given. These linkages to the NHDPlus linear stream network enable the use of these gaging stations for a variety of hydrologic analysis applications. Examples include the development of regional or national statistical models of streamflow and water-quality.
