The state of Idaho is supporting the creation of a IdahoWaters node through its EPSCoR program with them aim of not only providing a single access point for Idaho water information but also to make these data holdings accessible nationwide through participation in the network. Given the many individuals institutions that will participate in this effort, means of data submission are an extremely important aspect when developing an information node of this type. This paper demonstrates an architecture for the submission as well as querying and presentation of large datasets of hydrologic data via the internet. Discussed are the necessary hardware and software configurations used to create databases for staging, permanent storage, online analytical processing and distribution. In addition software and tools for decision support as well as automation for data extraction, transformation and loading are presented. Finally application of this architecture is shown for a wide-scale, distributed, hydrologic-based, collaborative information network.
