The database includes 1.5 million monitoring stations in the United States and Puerto Rico, some with nearly 100 years of data. A web service was developed using Visual Basic .Net to better expose this national-scale data resource to client applications within the hydrologic community. One such client application is an extension to the ArcMap that was developed by the author for plotting time series and performing basic water balance analysis within a mapping environment. The plotting extension was originally created to read from local databases, requiring the user to manually download time series and format them into a certain database structure. Now that the software has been extended to consume the NWIS web service, it is possible to create 'on-the-fly' plots of hydrologic observations for any station within nation.
