The Consortium of Universities for the Advancement of Hydrologic Science, Inc (CUAHSI) Hydrologic Information System (HIS) project is developing CyberInfrastructure (CI), and services to support the advance of hydrologic science in the United States. CUAHSI HIS developed CI supports storage of water observations data in a relational database, publication via web-services on the internet, federation with water observations data published by water agencies such as the U.S. Geological survey, and search across the various data holdings in the network. These advanced data access and analysis capability are provided through the use of web services using a format known as WaterML. An Observations Data Model (ODM) has been developed to provide a standard relational database schema for storing observatory and individual investigator data and also to serve as a central water metadata catalogue. We report on the latest developments of the Hydrologic Information Science (HIS) such as HydroServer and an open-source based GIS desktop application (HydroDesktop) for accessing web-services supported water information. We provide an overview of the system, the current state, and future plans.
