Abstract:
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.

The latitude and longitude coordinates of 2,195 gages were spatially referenced to the NHDPlusV1 flowlines. These locations were combined with DS-195
Process_Step:
Process_Description:
DS-195 gage locations and the additional/updated 2195 gage locations were indexed NHDPlusV1. This produced the Reachcode and Measure attributes from the NHDPlusV1 flowlines.
Process_Date: 2011
Process_Step:
Process_Description:
The gage locations with NHDPlusV1 Reachcodes and Measures were migrated to NHDPlusV2 stream network locations. The migration was performed as a three step process: (1) Gages which were located on Reachcodes that existed in both NHDPlusV1 and V2 were snapped to the same Reachcode in NHDPlusV2. (2) Of the remaining gages, Gages which were located on a stream name that existed in both NHDPlusV1 and V2 were snapped to the same named stream in NHDPlusV2. (3) The remaining gages were snapped to the nearest location in NHDPlusV2
