Stream and Lake Average Water-Level Altitudes, April-May 2013

Continuous records of water level altitude at 16 U.S. Geological Survey (USGS) streamgaging stations (15 streams and 1 lake) were retrieved from the National Water Information System (NWIS) and averaged for the months of April and May, 2013. This shapefile consists of the locations of those sites and includes water level altitude data stored in the attribute table. The shapefile was created and intended for use with geographic information system (GIS) software. The site locations and water level data are also presented in Sheet 1 of Scientific Investigations Map 3326.
