Website Pointer to the National Stream Internet

The National Stream Internet (NSI) is a network of people, data, and analytical techniques that interact synergistically to create information about streams. Elements and tools composing the NSI, including STARS, NHDPlusV2, and SSNs, enable integration of existing databases (e.g., water quality parameters, biological surveys, habitat condition) and development of new information using sophisticated spatial-statistical network models (SSNMs). The NSI provides a nationally consistent framework for analysis of stream data that can greatly improve the accuracy of status and trend assessments. The NSI project is described, together with an analytical infrastructure for using the spatial statistical network models with many types of stream datasets.
