Gage Locations (GageLoc.shp) indexed to the NHDPlus Version 2.1 stream network 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.

The position and extent of landforms are geospatially indexed as line-events where these coastal zone features are intersected by the linear-referenced 2013 - 2014 U.S. Geological Survey National Hydrography Dataset Coastline, which corresponds to the National Oceanic and Atmospheric Administration (NOAA) 2013 - 2014 mean high water level datum delineated in intertidal zones open to oceans, behind barrier coasts in bays, lagoons, and estuaries, and sometimes where tidal currents reach...

This dataset contains information about waterfall location and characteristics. It also provides a linear reference to two National Hydrography Datasets. This dataset is based off the World Waterfall Database (WWD) and other source datasets. The coordinates and spatial attributes from the WWD were used to help verify locations in Google Earth. From there, the USGS HydroLink Tool was used to link data to both the NHDPlusV2.1 (1:100,000 scale) and NHD High Resolution Dataset (1:24,000 scale). This dataset currently includes waterfalls from the states of Indiana, Wisconsin, Michigan, Nebraska, Illinois and Missouri....
