Learn more about deprecated software and tools: 

For many years the Hydrologic Information System (HIS) was a core part of CUAHSI's data services. Many tools and software packages have no been deprecated and are not supported anymore and the archive for the entire suite of HIS related tools is available here

CUAHSI no longer supports a standalone, local implementation of these tools and recommends using a CUAHSI hosted solution instead. Users can request an account to host their data in cloud at hydroserver.cuahsi.org

If you are still looking for key elements of the HIS system, please refer to the links below: 

  • HydroDesktop. HydroDesktop is a free and open source GIS enabled desktop application for finding and analyzing hydrologic data from the CUAHSI Hydrologic Information System. HydroDesktop is part of the legacy CUAHSI toolkit and is not under active development. 
  • WaterOneFlow (WOF). The CUAHSI-HIS uses a family of web services, called WaterOneFlow, that have been developed as a standard mechanism for the transfer of hydrologic data between hydrologic data servers (databases) and users computers. We no longer support local installations of WOF. 
  • Observations Data Model Tools. The ODM Tools application was created to allow administrators and users of ODM to visualize, manage, manipulate, edit and export data that have been imported to their local instance of the ODM facilitate data management. 
  • Observations Data Model Data Loaders. The ODM Data Loader provides a set of tools for loading metadata into an ODM database.
