The National Stream Internet (NSI) project was funded by the LCC program and led by researchers from USFS, CSIRO, NOAA, and USGS. The project developed a national analytical infrastructure for stream data that can be applied consistently anywhere in the country to develop new information at low cost. To create that infrastructure, the NSI project developed compatibility among key digital stream geospatial data and analysis tools. Those included the EPA/USGS NHD-Plus v.2 stream hydrography layer, sets of stream reach descriptors, and tools for implementing spatial statistical network models. The NSI enables consistent application of sophisticated analysis tools to many types of stream data throughout the U.S. Moreover, the spatial-statistical network models can be applied to databases characterized by non-random, clustered locations, which provides a strong incentive to develop comprehensive, inter-agency databases. The spatial models outperform traditional techniques applied to stream data and enable predictions at ungauged/unmonitored sites, which facilitates development of high-resolution status maps throughout full river networks. Like the real Internet, a Stream Internet requires a user-base, so free statistical software have been developed and annual training workshops are conducted in Boise, Idaho. A workshop for leaders of national aquatics programs was also held in 2015 to discuss potential future NSI applications. It is hoped that as better information is developed about stream resources and ecosystems, it empowers resource agencies and managers to make more efficient use of conservation resources and be more effective resource stewards.
